Knobs

Matrix encoder

This is the single control you use to build and adjust every connection on the wiring board. Spin it to move to the crossing point you want, click to 'open' that connection, then spin again to set how much effect it has — including negative amounts that push the opposite direction. Hold it down for a couple of seconds to erase a connection.

tip: To create an assignable destination, click into an Assign column point, then hold the matching Assign button (1, 2 or 3) and turn the knob you want to control — the display confirms the target. Subtlety usually wins: small amounts add expression, while full-force modulation often sounds crude.

A push-and-turn knob dedicated to the Matrix. Turning it scrolls the selection LED through all 35 patch points (wrapping around at the end); pressing it enters edit mode for the selected point, where turning sets a bipolar modulation amount and the display inverts to black-on-white. Holding it pressed for two seconds clears the selected point and resets its amount to zero.

Preset encoder

This is how you flip through sounds. Spin it to move through the library. Be careful: normally, moving to a new preset throws away any tweaks you made to the one you were on, without warning. It's also a fast eraser — click it three times in a row to wipe the current sound back to blank so you can start fresh.

tip: Turn on Utility > Browsing > Click to Load so you can audition presets while keeping your unsaved edits until you deliberately click. When naming a preset, push-and-turn edits a character in place, and holding Shift while turning jumps quickly through character ranges.

show text from manual

A push-and-turn knob next to the display used to browse and load the 256 preset slots (128 factory, 128 initially empty 'Init' presets, all overwritable). Turning scrolls presets; by default a new preset loads immediately, discarding unsaved edits, unless 'Click to Load' is enabled in Utility, in which case you scroll freely and click to load. Pressing it three times quickly resets the current preset to its empty Init state.

Master Volume knob

This is the overall loudness for the whole synth — it turns everything up or down at once, whether you're listening through headphones or a speaker. It's a straightforward volume knob and nothing more.

tip: Because this is a global control, use it to set a comfortable playing level, but adjust per-sound loudness elsewhere: Utility > Preset > Preset Volume lets you make one patch relatively louder or quieter (-12 to +12) so presets match in a set.

show text from manual

Sets the global output level of the MicroFreak, affecting both the line output and the headphone output simultaneously. It is one of only two controls that cannot be used as a Matrix modulation destination (the other being the Preset encoder).

Glide knob

This makes notes swoop into each other instead of jumping cleanly. Turned up, moving from one key to another glides the pitch like a slide guitar or a singer bending between notes. Fully left, pitches change instantly. It's great for expressive leads and basslines.

tip: For extra expression, make Glide a Matrix destination and modulate it with keyboard Pressure — press harder to add more slide. In Sync mode with the LFO controlling Glide, you can make glide switch on and off every other sequencer step for rhythmic slides.

show text from manual

Sets the portamento amount — the time or rate for pitch to slide smoothly from one note to the next. Fully counter-clockwise means no glide (instant pitch changes); clockwise increases it, up to roughly 4 seconds to travel the keyboard's two-octave span (the range extends to about 10 seconds). The behavior is set in Utility > Preset > Glide Mode: Time (fixed duration), Sync (locked to tempo divisions like 1/16, 1/8, 1/4 up to 1/1), or Rate (relative to Arp/Seq rate).

Type knob (Digital Oscillator)

This is the big choice: it swaps out the entire sound-generating personality of the synth. One setting gives you classic analog-style waves, another gives you spoken words, another plucked strings, another chords, another metallic bell tones. Turning it while playing walks you through completely different flavors of sound. The display shows a picture of whichever engine you land on.

tip: Because Type only changes when a fresh note starts, modulating it with the LFO or Arpeggiator creates abrupt, glitchy engine-hopping timbre changes between notes rather than smooth morphing. Try that for chaotic, unpredictable textures.

show text from manual

Selects the oscillator's synthesis model. The MicroFreak offers many engines including Basic Waves, Superwave, Wavetable, Harmonic, KarplusStrong, and the Mutable Instruments-derived Plaits models: PI.VA (classic waveforms), PI.Waveshapr (waveshaping/fold), PI.FM (two-operator FM), PI.Grain (granular formant), PI.Chords, PI.Speech (vowel/speech), and PI.Modal (modal resonator). Type can also be modulated in the Matrix, though it only updates the model when a new note is triggered, not while a note is held.

Wave knob (Digital Oscillator)

Think of this as the main tone-tweaker for whatever engine you picked. What it does changes depending on the engine, but it's always the biggest character control after Type. The display tells you exactly what it's changing as you turn it, so watch the screen. On the chord engine it picks the chord; on the speech engine it picks the word.

tip: Modulating Wave with the LFO or Cycling Envelope is one of the most rewarding tricks on the MicroFreak. On the Wavetable engine this is called wavesequencing; on PI.Chords, modulating Wave with the LFO random wave (set strength 50–100) gives instant evolving chord changes.

show text from manual

Adjusts the first of three sound-shaping parameters for the currently selected oscillator model; its exact function depends on the Type. Examples: in Basic Waves it morphs square to sawtooth; in Superwave it picks which waveform gets multiplied; in Wavetable it selects one of 16 waves; in PI.Chords it selects the chord (Octave, 5th, sus4, minor variants, major variants, etc.); in PI.Speech it scans formants then libraries of colors, numbers, letters and words. In the Plaits models it corresponds to the parameter Mutable calls 'Harmonics'. Wave is available as a modulation destination in the Matrix.

Timbre knob (Digital Oscillator)

This is the second tone control for your chosen engine, and like Wave it does something different for each one. Often it adds thickness, movement or brightness. On FM it controls how clangy and metallic the sound gets; on the chord engine it flips the chord notes around into different voicings; on the speech engine it shifts the voice up or down.

tip: On engines that detune (like Superwave, Timbre = detune amount), small amounts give a lush, fat chorus-like richness while large amounts get wild and dissonant.

show text from manual

Adjusts the second sound-shaping parameter of the selected oscillator model; behavior varies by Type. Examples: pulse-width or sawtooth phasing in Basic Waves, detune amount in Superwave, browsing the 32 cycles in Wavetable, chord inversion/frequency range in PI.Chords, formant shift in PI.Speech, modulation index in PI.FM. In Plaits-derived models it maps to the parameter Mutable calls 'Timbre'. Available as a Matrix modulation destination.

Shape knob (Digital Oscillator)

The third and final tuning knob for your chosen engine, usually adding the finishing touch—extra width, a chorus shimmer, more sustain, or extra harmonics. As always, the display shows what it's actually doing for the current engine.

tip: On the Modal engine, Shape controls how long the sound rings out (damping/decay). In paraphonic mode, modulating it lets you selectively mute or sustain individual notes of an arpeggio or sequence.

show text from manual

Adjusts the third sound-shaping parameter of the selected oscillator model; behavior varies by Type. Examples: adds a sine sub-oscillator in Basic Waves, sets detuned-wave amplitude in Superwave, adds a chorus effect in Wavetable and Harmonic, sets resonance/decay in KarplusStrong, sets FM feedback in PI.FM, sets damping/decay in PI.Modal, and selects the waveform in PI.Chords. In Plaits-derived models it maps to the parameter Mutable calls 'Morph'. Available as a Matrix modulation destination.

Cutoff knob (Analog Filter)

This is the tone-brightness dial and probably the knob you'll grab most. In Low Pass mode, turning it down makes the sound progressively darker and muffled until it disappears; turning up opens it bright and full. In High Pass mode it works the opposite way. It's the classic 'wah' and 'sweep' control of any synth.

tip: Cutoff comes alive when moved automatically rather than by hand—let the Envelope (via Filter Amt), the LFO, or a sequencer modulation track sweep it. For a manual filter-sweep test, set Cutoff low, Resonance high, Amp Mod on, and dial in a slow attack/long decay on the envelope.

show text from manual

Sets the cutoff frequency—the point where the filter starts acting. Range runs from roughly 30Hz fully counter-clockwise to over 15kHz fully clockwise. Its meaning depends on the filter Type set by the Type button. The main Envelope is hardwired to modulate cutoff via the Filter Amt knob, and cutoff also appears as a fixed Matrix destination.

Resonance knob (Analog Filter)

This adds a whistling, ringing emphasis right at the point where the filter is cutting. A little gives the sweep a vocal, singing quality; a lot makes it scream and ring. Pushed to the maximum the filter starts making its own pure tone even with no oscillator.

tip: Max the resonance and the self-oscillating filter becomes a clean sine-wave source—handy since the Basic Waves engine has no dedicated sine. Also great for accenting individual beats in an arpeggio when you modulate it from a sequencer track.

show text from manual

Also called Emphasis or Q. Boosts the frequencies right around the cutoff point by feeding the filter's output back into itself, creating a resonant peak. Turned fully clockwise the filter self-oscillates, producing a pure sine tone; in Band Pass mode maximum resonance narrows the passband and can block the oscillator entirely while ringing as a sine oscillator. Resonance is available as an assignable Matrix modulation destination.

Rise knob (Cycling Envelope)

This controls how quickly the Cycling Envelope's swell builds up. Short means an instant jump; long means a slow fade-in. Since the Cycling Envelope can loop, at very short settings it becomes a shape you can use like a second LFO. Hold Shift and turn it to change the curve from gentle-then-fast to fast-then-gentle.

tip: Set Rise, Fall and Hold all very low and switch to Loop or Run mode to turn the Cycling Envelope into a fast, custom-shaped extra LFO—then modulate its Rise time with the real LFO for constantly shifting waveforms.

show text from manual

Sets the rise (attack) time of the Cycling Envelope—the time the envelope takes to climb to maximum after being triggered. In Env mode it acts like a normal attack stage; in Run and Loop modes it shapes the up-slope of the repeating cycle. Holding Shift while turning Rise sets the shape of the rise stage: turn left for logarithmic, right for exponential, with a linear dead zone in the middle (the screen shows 'LINEAR'). Rise is available as a Matrix modulation destination.

Fall knob (Cycling Envelope)

This controls how quickly the Cycling Envelope's swell dies away. Short gives a snappy, percussive drop; long gives a slow, gradual fade. Combined with Rise it defines the whole up-and-down shape of the cycle. Hold Shift and turn it to bend the curve for a more aggressive or more relaxed tail.

tip: Feeding the LFO's rising sawtooth into the Fall time adds realistic variation to drum- and bell-like decays. Remember a logarithmic rise plus exponential fall feels sluggish, while the reverse feels punchy and eager.

show text from manual

Sets the fall time of the Cycling Envelope—how long it takes to drop back to zero. In standard Env mode this is the release after you let go of a key; in Run and Loop modes it sets the down-slope of the repeating cycle before it retriggers. Holding Shift while turning Fall sets the shape of the fall stage: left for logarithmic, right for exponential, linear in the middle. Fall is available as a Matrix modulation destination.

Hold knob (Cycling Envelope)

This sets how long the Cycling Envelope stays at full before it starts falling. In the looping modes, a longer Hold keeps the sound sitting at its peak for a beat before dropping, changing the rhythm and shape of the repeating cycle. In normal mode it acts as the sustain level while you hold a key.

tip: When using the Cycling Envelope as a repeating LFO-like source, adjusting Hold reshapes the waveform's flat-top duration—a small Hold makes a pointier peak, a longer Hold makes a plateau, useful for gating or pulsing effects.

show text from manual

Sets the Hold/Sustain stage of the Cycling Envelope, which sits between the Rise and Fall stages. In Env mode the level is held as long as a key is pressed (functioning as sustain level); in Run and Loop modes Hold sets how long the envelope stays at its peak before beginning the Fall stage. Hold is available as a Matrix modulation destination.

Amount knob (Cycling Envelope)

This is the master volume knob for the Cycling Envelope's 'move'. Turn it up and the envelope pushes harder on whatever it's controlling (pitch, filter, wave, etc.); turn it down and the effect gets gentler. If it's set to zero, the Cycling Envelope does nothing no matter how you shape it.

tip: When you're using the Cycling Envelope on the analog filter, small amounts often sound best — sending too much or too little is the difference between an average and a fantastic sound. Try modulating this Amount knob itself with the LFO or pressure for evolving depth.

show text from manual

Sets how strongly the Cycling Envelope's output affects whatever destinations it's routed to on the Matrix. It acts as an attenuator on the Cycling Envelope signal, scaling the overall depth of the modulation it sends out. It's also available as a modulation destination in the Matrix (CYCLING Envelope AMOUNT).

Rate knob (Arpeggiator/Sequencer)

This is the tempo dial for your arpeggios and sequences — turn right for faster, left for slower. Push it in to lock to a clock so it stays in time with your other gear, or leave it free to set your own beats-per-minute.

tip: Hold Shift and turn this knob to add swing for a looser, groovier feel. During step recording, turning it 'scrubs' through your sequence step by step so you can find and edit individual steps.

show text from manual

Sets the playback speed of the Arpeggiator or Sequencer. Unsynced it displays BPM (default 120.0). Pressing it toggles Sync; when synced it locks to the internal or external clock and shows note divisions from 1 whole note down to 1/32 triplet. Holding Shift while turning sets a swing amount (50–75%).

Rate knob (LFO)

Controls how fast the LFO's wobble moves — from a slow drift taking many seconds, up to fast enough to sound almost like a tone. Push the knob in to lock the speed to your song's tempo so the wobble stays in rhythm.

tip: When synced, values like 1/4 mean one LFO cycle per quarter note — handy for tremolo and filter sweeps that stay locked to the beat. To make the LFO restart cleanly with every note, turn on Utility>Preset>LFO Retrig.

show text from manual

Sets the LFO speed from 0.06 Hz up to 100 Hz (default 1 Hz when unsynced). Pressing the knob toggles Sync: when off, the value shows in Hz; when on, the LFO locks proportionally to the MicroFreak or DAW clock and displays as divisions from 8/1 down to 1/32, including triplet values.

Attack knob (Envelope)

Controls how quickly the sound (or the filter opening) fades in when you press a key. Fully counter-clockwise gives an instant, snappy start like an organ or pluck. Turn it up and the note swells in gradually, like a bowed string section that takes a moment to reach full volume.

tip: Keep it near zero for percussive, bass and lead sounds so they hit right on time; dial in longer attacks (a second or more) for pads and evolving textures. You can also make it a modulation destination in the Matrix (via an Assign slot) so pressure or the LFO can vary the attack per note.

show text from manual

Sets the Attack time of the main (Standard) Envelope Generator, from 0 ms to 10 seconds. This is the time the envelope takes to rise from zero to its maximum level after a key is pressed. By default the envelope controls the filter cutoff, and it also controls volume when the Amp Mod button is lit.

Decay/Release knob (Envelope)

Controls how fast the sound settles down after the initial hit, and how long it takes to die away once you lift your finger. Short settings give tight, plucky, percussive notes; long settings let notes ring out and fade slowly after you let go.

tip: Note that on the MicroFreak decay and release share one knob, so you can't set them independently. For drum and bell-like sounds, use a short-to-medium setting with a low Sustain. Modulating this with the rising Saw wave of the LFO adds realism to percussive sounds.

show text from manual

Sets the Decay/Release time of the main Envelope, from 0 ms to 13 seconds. This is the time the envelope takes to fall from the peak (end of Attack) down to the Sustain level, and also the time it takes to fall to zero after you release the key.

Sustain knob (Envelope)

Sets how loud (or how open the filter stays) while you keep holding a key down. Turn it high and notes stay full and steady as long as you hold them, like an organ. Turn it low and the note drops to a quiet level (or silence) right after the initial hit, which is what you want for plucks and drums.

tip: If Sustain is set to maximum, the Decay knob has no audible effect because there's nothing left to decay to. Set it low for percussive patches and high for sustained pads, leads and drones.

show text from manual

Sets the Sustain level of the main Envelope. This is the level the envelope holds at after the Decay stage, for as long as a key (or gate) is held. Because Sustain is a level rather than a time, the MicroFreak envelope is technically an ADS envelope.

Filter Amt knob (Envelope)

Decides how strongly the envelope opens (or closes) the filter as a note plays, which shapes how bright the sound gets and how that brightness changes over time. This is the knob that creates the classic 'filter sweep' where a note starts bright and mellows out, or starts dark and blooms open.

tip: Because it's bipolar, turning it one way makes the filter open with the envelope and the other way makes it close. Try Cutoff low, Resonance high, and Filter Amt around 70 with a long attack and decay to hear a dramatic sweep. You can fine-tune this same amount directly on the Matrix if you prefer.

show text from manual

Sets how much of the main Envelope's output is routed to the Filter cutoff frequency. This is a hardwired connection; turning the knob lights the corresponding Envelope-to-Cutoff point on the Matrix. The control is bipolar, so it can sweep the cutoff up or down.

Buttons

Paraphonic button

Lit, this lets you play chords — up to four notes at once — instead of just one note at a time. All the notes pass through the same filter, so they share a general tone color, but each note can rise and fall in volume on its own, which sounds more natural than typical chord-capable budget synths.

tip: Chord-heavy oscillator modes behave differently: in the Chords oscillator type, paraphony deactivates and one chord plays from the single root note you hold. In the Speech mode, turning paraphony on can make the synth 'say' a word with four stacked voices for a thicker effect.

show text from manual

Toggles paraphonic mode, allowing up to four voices to be triggered independently while sharing the single analog filter. Unlike most paraphonic synths, the MicroFreak gives each voice its own internal invisible VCA envelope, so voices can have different volumes. Polyphonic sources (Main Envelope, Pressure, Keyboard, Arpeggiator) applied to polyphonic destinations (the Oscillator's Type, Wave, Timbre, Shape) modulate each voice separately.

Panel button

Because this synth remembers presets but has knobs that don't physically move, the knob positions usually lie about the real settings. Press Panel to make the knobs tell the truth — the sound instantly matches exactly where every knob is pointing. It's the honest, hands-on mode for building a sound from scratch.

tip: Keep Panel OFF while browsing presets so you hear them as intended. Turn it ON when you want a clean starting point or when you're confused about why a knob isn't doing what its position suggests. Note that in the default 'Hook' knob mode you otherwise have to sweep a knob past its hidden value before it takes effect.

show text from manual

Toggles between the stored preset's saved knob positions and the physical positions of the front-panel knobs. When Panel is ON, what you hear reflects the actual current knob positions (knob-say, knob-do). When OFF, you hear the preset as saved, regardless of where the knobs currently sit.

Save button

This locks in your sound so you don't lose it. Hit it and follow the prompts to name your creation, tag it with a category, and pick where to store it. Everything about the patch gets remembered — including any sequence you recorded and the knob wiggles in its modulation tracks.

tip: A long press on Save does a quick save to the current slot. If you see 'Memory protect is on,' go to Utility > Misc > Mem Protect and set it to OFF (or 'Factory only' if you just want to protect the factory sounds). Save early and often — switching presets can wipe your edits without warning.

show text from manual

Enters save mode to store the current preset either to its existing slot or a new location. The process lets you turn the encoder to pick a destination slot, choose a category (Bass, Brass, Keys, Lead, Pad, Percussion, Sequence, SFX, Strings), and enter a name. Saving stores knob positions, both sequences and their modulation tracks, and the preset-specific Utility settings. Spice & Dice and Hold states are not saved. Saving is disabled while in Utility mode.

Utility button

This is the settings menu — the deeper options that don't have their own knob. Some settings are global (like overall tuning), and some are stored per-sound (like how loud that patch is, how the keyboard responds to pressure, or how long its sequence is). Adjusting these can dramatically change how a sound feels to play.

tip: Many of the synth's 'secret' behaviors live here: switch the keyboard between pressure and velocity (Utility > Preset > Press mode), change Glide from Time to Rate, set default gate length, or turn on LFO retrigger. Remember to exit Utility before trying to save — you can't save while it's open.

show text from manual

Opens the Utility menu, which holds both global settings (tuning, MIDI, sync, CV/Gate formats, keyboard sensitivity, memory protection) and preset-specific settings (Preset Volume, Bend Range, Press mode, Glide Mode, sequence length, envelope reset/legato, and more). Preset-level settings are saved with each preset; global settings apply everywhere. Saving is not possible while Utility is active.

Type button (Analog Filter)

This picks which direction the filter cleans up your sound. Low Pass keeps the lows and cuts the highs (warm, mellow). High Pass keeps the highs and cuts the lows (thin, bright, good for cutting through a mix). Band Pass keeps only a narrow slice in the middle (nasal, focused). Press to cycle through the three.

tip: The 12dB slope is gentler than many synths' 24dB filters, which suits the MicroFreak's harmonically rich oscillators—it filters without dulling them. Use High Pass to clear out low-end mud when layering the MicroFreak under a bass part from another synth.

show text from manual

Switches the analog filter between its three modes: Low Pass Filter (LPF), Band Pass Filter (BPF), and High Pass Filter (HPF). The filter has a 12dB-per-octave roll-off. LPF removes frequencies above the cutoff, HPF removes frequencies below the cutoff, and BPF removes frequencies both above and below the cutoff, leaving only a band around it.

Mode button (Cycling Envelope)

This decides whether the Cycling Envelope fires once or keeps repeating. In Env mode it does its rise-and-fall once each time you play a note. In Run mode it loops forever on its own. In Loop mode it loops but restarts in time with the notes you play or the sequencer. When it loops with short times, it turns into a custom-shaped wobble source.

tip: For a complex LFO you can't get from the normal LFO, put it in Loop or Run mode and set Rise, Fall and Hold very low — then reshape those stages to draw your own waveform. In Loop mode, trigger it from the arpeggiator at ~55 bpm to hear it retrigger on every step.

show text from manual

Selects one of three run modes for the Cycling Envelope: Env (standard one-shot envelope), Run (free-running, resets on MIDI start), and Loop (retriggers on each keyboard/sequencer/arpeggiator gate). In Run and Loop modes the envelope repeats itself and behaves like a second, shapeable LFO.

Octave Down button

Shifts everything you play lower by whole octaves so you can reach bass notes the little 25-key keyboard can't otherwise play. Press it again to go even lower.

tip: Watch the blink speed to know how far you've shifted on a dark stage — faster flashing means you're further from normal pitch. The keyboard is two octaves but the full range spans eight octaves using these buttons.

show text from manual

Transposes the keyboard's playable range downward in one-octave steps, up to three octaves below the center point. The blink rate of the button increases the further you move from the zero point, flashing fastest at -3. Octave shift is saved with the preset.

Octave Up button

Shifts everything you play higher by whole octaves so you can reach high leads and sparkle the small keyboard can't otherwise reach. Press again to go higher still.

tip: When playing an arpeggio, pressing this while notes are held doesn't just transpose — the MicroFreak keeps your existing arpeggio intact and adds the new notes you play in the higher octave, letting you build up wide-range patterns.

show text from manual

Transposes the keyboard's playable range upward in one-octave steps, up to three octaves above the center point. The blink rate increases the further from zero you go, fastest at +3. Octave shift is saved with the preset.

Shift button

This is the 'hold me and do something else' key. On its own it does nothing, but held down it turns other knobs and buttons into their alternate jobs — like adding groove, changing envelope curves, or switching between the arpeggiator and sequencer.

tip: Hold Shift and turn the Rate encoder to dial in swing (50% straight up to 75%) — great for adding a jazzy, human feel to arpeggios and sequences. Hold Shift + Rise or Shift + Fall to bend the Cycling Envelope curves from logarithmic through linear to exponential.

show text from manual

A modifier button (labeled in blue) that unlocks secondary functions across the panel. Holding Shift lets you toggle between Arp and Seq, set a swing rate (Shift + Rate), shape the Attack/Rise stage of the Cycling Envelope (Shift + Rise), shape the Fall stage (Shift + Fall), transpose or reload sequences, and copy an arpeggio to a sequence.

Arp | Seq button

Press it to make held chords play as a rolling, note-by-note pattern instead of all at once. Press again to turn that off. Hold Shift while pressing it to jump into the step Sequencer instead, for recorded melodies.

tip: Press Hold first, play and hold a chord, then hit Arp | Seq — the arpeggio keeps running hands-free so you can tweak knobs. Found a great arpeggio? Shift + Up|A or Shift + Order|B copies it straight into a sequencer.

show text from manual

Toggles the Arpeggiator on and off; it lights white when the Arpeggiator is active. Holding Shift and pressing it switches to the Sequencer instead. The Arpeggiator plays held notes back one at a time according to the pattern icons and octave range setting.

Oct | Mod button

It does two different jobs depending on mode. With the arpeggiator running, it makes the pattern climb through more octaves for a bigger, busier sound. With the sequencer running, it's how you flip between the four knob-movement recording lanes.

tip: In the Sequencer, hold Oct | Mod and press Hold to erase the current modulation track; keep holding Oct | Mod and tap Hold repeatedly to wipe all four modulation tracks quickly.

show text from manual

When the Arpeggiator is active, sets its octave range from 1 to 4 (held notes only, or repeated one, two, or three octaves above). When the Sequencer is active, it selects which of the four modulation tracks you're viewing or editing, and is used with Hold to clear modulation tracks.

Shape button (LFO)

Picks the 'personality' of the LFO's automatic movement. Sine and triangle give smooth up-and-down sweeps; sawtooth ramps then jumps; square flips between two values; random stepped jumps around unpredictably; random gliding wanders smoothly. Whatever you send it to — pitch, filter, wave — takes on this motion.

tip: For that classic sci-fi computer bleeping, choose random stepped, route LFO to Pitch on the Matrix, set speed around 25 Hz and modulation amount around 400. The random gliding wave is great for subtle, organic drift.

show text from manual

Cycles the LFO through its six waveforms: sine, triangle, rising sawtooth, square (50% duty cycle), random stepped (sample & hold), and random gliding (smoothed random). The selected wave determines the shape of the modulation the LFO sends.

Amp Mod button (Envelope)

Switches between two ways the volume behaves. With it off, sound just turns fully on while a key is held and off when released, an abrupt on/off. With it on, the Attack/Decay/Sustain knobs also shape the loudness, so notes can fade in and out smoothly instead of just clicking on and off.

tip: Leave it ON for musical amplitude shaping (fade-ins, plucks, swells). Turn it OFF when you want the arpeggiator or sequencer gates to control volume directly, or when you only want the envelope affecting the filter.

show text from manual

Toggles whether the main Envelope controls the internal VCA (volume). When lit, the Envelope shapes the overall loudness in addition to always feeding the Filter cutoff. When off, the raw keyboard/sequencer Gate signal controls the VCA directly. In Paraphonic mode with Amp Mod on, the envelope is duplicated to control each voice's internal VCA.

Hold icon button (Icon strip)

Locks whatever you're playing so it keeps going without you touching the keys, freeing both hands to tweak knobs. It's especially handy for keeping an arpeggio or held chord running while you turn other controls, or for building evolving, self-playing sounds.

tip: When you find a great Pattern arpeggio, press Hold and stop touching the keyboard, otherwise playing again generates a brand-new pattern and loses it. To hold external MIDI notes instead, send the MicroFreak a Sustain message. During sequencing it doubles as your tie/rest/clear tool depending on the mode.

show text from manual

Latches the currently held keys or chord so they keep sounding after you lift your fingers. In Arp mode it keeps the arpeggio running; playing new keys replaces the held notes. In Sequencer step-record mode it adds a tie or rest; in real-time record it clears content; combined with Seq Mod or A/B it acts as a Clear button. The Hold state is not saved with the preset and does not work with external MIDI.

Up | A icon button (Icon strip)

In arpeggiator mode this makes your held chord play its notes in order from bottom to top, over and over, the most classic arpeggio motion. In sequencer mode the same button picks Sequence A, one of the two sequences stored in each preset.

tip: Hold this button together with the Hold icon for about one second to clear Sequence A. Use Shift + Up | A to capture a good live arpeggio straight into Sequence A so you can keep and edit it.

show text from manual

A dual-function icon whose role depends on the Arp | Seq state. When the Arpeggiator is active it selects the 'Up' arpeggio mode, playing held notes from lowest to highest regardless of the order you pressed them. When the Sequencer is active it selects Sequence A. Shift + Up | A transfers the current arpeggio into Sequencer A.

Order | B icon button (Icon strip)

In arpeggiator mode this plays your chord notes back in the same order your fingers touched the keys, so changing how you finger the same chord changes the melodic pattern. In sequencer mode the button chooses Sequence B, the second sequence in the preset.

tip: Order mode is great for expressive, hand-controlled arpeggios: replay the same chord with different finger order for instant variations. Hold this with the Hold icon for one second to clear Sequence B, and use Shift + Order | B to save a live arpeggio into Sequence B.

show text from manual

A dual-function icon. With the Arpeggiator active it selects 'Order' mode, playing held notes in the exact order you pressed them. With the Sequencer active it selects Sequence B. Shift + Order | B transfers the current arpeggio into Sequencer B.

Random | 0 icon button (Icon strip)

In arpeggiator mode this shuffles your held notes into a constantly random order for unpredictable, lively patterns. When you're working with the sequencer instead, this button arms step-by-step recording so you can enter notes one step at a time.

tip: Random mode adds movement to static chords without any programming. When sequencing, remember this is your record button for step entry, press it with the sequencer stopped, then hold notes for each step.

show text from manual

A dual-function icon. With the Arpeggiator active it selects 'Random' mode, playing the held notes in a random order. With the Sequencer active (labelled 0) it turns on step recording when the sequencer is stopped.

Pattern | > icon button (Icon strip)

In arpeggiator mode this is like a built-in third sequencer: it invents a fresh, musical-sounding note pattern from your held chord every time you press new keys. In sequencer mode the same button is your play/stop transport control.

tip: When Pattern gives you a groove you love, hit Hold and don't touch the keyboard again, or a new pattern will overwrite it; you can then use Shift + Up | A or Order | B to save it as a sequence. Note that when playing, pressing Play/Stop also sends MIDI and analog clock start/stop signals to synced gear.

show text from manual

A dual-function icon. With the Arpeggiator active it selects 'Pattern' mode, a semi-random algorithm that generates a new arpeggio pattern each time you press keys (the root/lowest note appears twice as often, and pattern length follows Utility>Preset>Seq length). With the Sequencer active (labelled >) it toggles between Play and Stop and also stops step recording.

Spice icon button (Icon strip)

Think of Spice as the 'how much' knob for randomizing the rhythm of your arpeggio or sequence. Once you've rolled the Dice to shuffle around the note lengths and gaps, Spice controls how strongly those changes are actually applied. With Spice at zero you hear the original pattern; slide it up and the rhythmic variation the Dice created becomes more and more audible, making steps longer, shorter, or dropping them out.

tip: Set an amount of Spice first, then tap the Dice repeatedly at different spots on the touch strip to audition variations at that fixed intensity — great for finding a groove live. Remember these tweaks vanish when you change presets, so record into a DAW if you want to keep a happy accident.

show text from manual

Selects the Spice function on the touch strip. Spice sets the intensity of the gate/trigger deviation applied to the currently playing arpeggio or sequence. At maximum Spice the gate lengths match what is currently defined in the sequence's 'Status'; in between, gate lengths morph linearly from the default gate length toward that Status. Spice works together with Dice and cannot be used alone. Spice & Dice settings are NOT saved with the preset.

Dice icon button (Icon strip)

Dice is the 'reshuffle' button for your rhythm. Every time you tap the touch strip with Dice active, MicroFreak throws new dice and rearranges which steps are long, short, or silent. Tap gently on the left of the strip for subtle nudges, or hit the right side to scramble the whole thing. You won't hear anything change until you've also dialed in some Spice.

tip: Spice & Dice are to note timing what the Pattern button is to pitches — together they can transform a sequence beyond recognition. Use them for live performance surprises; what they generate is unique and cannot be recalled.

show text from manual

Selects the Dice function on the touch strip. Dice acts on the gates and triggers of the currently playing arpeggio or sequence, randomizing the distance between triggers and shortening, lengthening, or omitting gates. Each touch of the strip adds a new bipolar value to the gate length of every step, modifying the sequence 'Status'. Touching near the left applies a slight change; near the right completely reshuffles the Status. The last heard result becomes the new Status. Requires Spice to be audible.

Bend icon button (Icon strip)

Press this to make the touch strip act like a pitch-bend wheel — but better. Instead of always starting from the middle, you can jab your finger straight onto any point and the pitch instantly leaps there, or tap between two spots to flip quickly between two pitches. Lift your finger and the pitch drifts back to center. Wiggling your finger gives natural vibrato.

tip: There are six little tilted markers printed on the strip to help you hit accurate intervals. Set the bend range to 12 in Utility and you can 'play' an arpeggio across a whole octave just by tapping different spots on the strip (make sure Relative bend is OFF).

show text from manual

Selects the Bend function on the touch strip, turning it into a pitch-bend controller. The center of the strip is neutral; sliding left or right bends pitch down or up. By default the bend range is 24 chromatic steps (12 each way), configurable up to 48 steps (four octaves) via Utility>Preset>Bend. In default (absolute) mode the pitch jumps to wherever you touch; in relative mode (Utility>Misc>Relative bend ON) movements are added or subtracted from the current pitch regardless of where you touch.

Display & indicators

Matrix (modulation patch grid)

This is the wiring board that decides what wobbles, sweeps, or shapes what. Instead of physical cables, you pick a point where a 'mover' (like the LFO) meets a 'thing to move' (like pitch or filter), and dial in how strongly it happens. It's how you create vibrato, filter sweeps, evolving textures, and much weirder effects — without any patch cords.

tip: Destinations 1–4 are fixed (Pitch, Wave, Timbre, Cutoff), but slots 5, 6 and 7 (Assign1–3) can target almost any knob on the synth — everything except Master Volume and the Preset encoder. You can even route a source to the 'Matrix Modulation Amount' of another point, meaning you can modulate a modulation (for example, use the Cycling Envelope to fade vibrato in and out).

show text from manual

A 5-row by 7-column grid of 35 patch points that connects modulation sources (rows: Cycling Envelope, Envelope, LFO, Pressure, Key/Arp) to destinations (columns: Pitch, Wave, Timbre, Cutoff, plus three assignable slots). Each intersection has a bipolar attenuator, so modulation can be positive or negative. A moving LED indicator shows which point is selected, and LED states report status: off means no routing (or amount at zero), on means a routing exists, blinking means you're editing that connection's strength.

OLED display

This little screen is your constant guide — it tells you what you're doing the moment you touch anything. Turn a knob and it names what's changing and shows the value; pick an oscillator and it draws a picture of it. It removes most of the guesswork from a synth that otherwise hides a lot under the hood.

tip: Watch it closely when editing the Matrix: it names the exact parameter you're assigning (for example, 'parameter 3 of the oscillator' is Shape) and shows the modulation strength as you dial it, which is the only reliable way to know what an Assign slot is actually controlling.

show text from manual

A low-power OLED screen that shows contextual information: the name and category of the current preset, real-time feedback on any knob you turn or button you press, graphic representations of the selected oscillator Type and its parameter values, Matrix connection info and modulation amounts, sequencer step data, LFO sync ratios, and Utility menu settings.

Other

Touch strip

This is the flat, wheel-free strip you slide or tap your finger along. Depending on which icon you've selected, it either controls how wild your rhythm gets (Spice/Dice) or bends the pitch of your notes (Bend). Because it senses exactly where you touch, you can jump instantly to any value instead of gradually sweeping to it like a wheel.

tip: You can play the strip dynamically — tapping various positions on the fly rather than just sliding — which is what makes it far more expressive than a traditional pitch wheel.

show text from manual

A capacitive ribbon controller above the keyboard that performs one of three functions at a time, chosen by the Spice, Dice, or Bend icons next to it. It responds to finger position and can be tapped at different points for dynamic control. For Spice/Dice it sets randomization intensity and rolls new rhythmic variations; for Bend it acts as a position-sensitive pitch bender.

Touch capacitive keyboard (25 keys)

Instead of keys that move up and down, these are flat pads that sense your finger. Pressing a key both plays a note and, as you roll more of your fingertip onto it, sends out an expressive 'pressure' signal you can route to control almost anything — like brightness, vibrato, or volume. You choose in the menus whether the keys respond to how hard/how much finger you use (pressure) or how fast you strike (velocity).

tip: If your fingers are dry and the keyboard feels unresponsive, lick your fingertip — seriously, the manual suggests it, since the keyboard works by sensing skin contact. Because pressure settings save per-preset, you can make two identical presets with different keyboard responses for a live set. Clean the keys with a soft damp cloth (no abrasives).

show text from manual

A 25-key touch-sensitive capacitive keyboard (no moving keys) spanning two octaves, extendable via the Octave buttons. Each touch generates a gate, a pitch, and a pressure (or velocity) signal, selectable at Utility>Preset>Press mode. The larger the finger contact area, the higher the pressure value — finger surface alone reaches about 30% of the range, with added pressure reaching 100%. These signals are available in the Matrix and at the rear Pitch/Gate/Pressure outputs. It can also act as a polyphonic MIDI controller.

Side panels

Switches & toggles

Power switch

This is simply the on/off button, tucked into the panel so it isn't bumped by accident. It turns the whole instrument on and off whether you're powering it from the wall or over USB.

tip: Following good practice, power up your audio system in order — turn the MicroFreak on before your amplifier or speakers, and turn it off after them, to avoid pops. Because it's recessed, you can leave cables connected and just flip this switch to shut down.

show text from manual

A recessed switch on the rear panel that toggles the unit between OFF and ON (USB power or DC power). It lets you power down without unplugging the USB cable. When both DC and USB are connected, DC is used; switching to DC power causes the MicroFreak to reset.

Jacks & connectors

Headphone output (1/8" TRS)

This is where you plug in headphones. Even though most headphones are stereo, MicroFreak only makes mono sound, so both ears get exactly the same thing — that's normal, not a fault.

tip: Use this for quiet practice, but remember the Master Volume affects both this and the line output, so set levels carefully to protect your ears.

show text from manual

A standard 3.5mm (1/8") TS or TRS jack for headphones. The output signal is monaural — plugging in stereo headphones simply sends the identical sound to both left and right sides. Its level is controlled by the Master Volume knob.

Line output (6.35mm TRS)

This is the main output you run to your mixer, audio interface, or amp. It's mono like everything else on the MicroFreak. Because it's a balanced output, using the right kind of cable gives you a cleaner, quieter signal.

tip: Use a TRS (balanced) cable here rather than a standard TS instrument cable — the manual specifically notes it improves the signal-to-noise ratio, meaning less hiss, especially over longer cable runs.

show text from manual

A 6.35mm (1/4") TRS jack providing a monaural, balanced/symmetrical line-level output for connecting to an amplifier or mixer. Using a TRS (balanced) cable improves the signal-to-noise ratio versus a TS cable.

Pitch (CV) output

This sends out an electrical 'note number' so MicroFreak can play the pitch of external analog synthesizers and modular gear that don't understand MIDI. As you play higher notes, the voltage rises, telling the other synth to play higher too.

tip: If an external oscillator won't track in tune, check the pitch format setting — most gear (Eurorack, Arturia Brutes) wants 1V/octave, but some vintage synths need Hz/V or Buchla's 1.2V/octave. The manual recommends ferrite-equipped CV cables to reduce noise.

show text from manual

A control-voltage output that transmits the pitch of the currently played/sequenced note to external analog gear such as Eurorack modules or Arturia's Brute-series synths. By default it follows the 1V/octave standard, but can be set to Hz/V or 1.2V/octave (Buchla) in Utility or the MIDI Control Center. The 0V/1V reference note is also configurable. Only one pitch CV is output, so on chords the lowest note is sent.

Gate output

This tells an external synth or module WHEN a note starts and stops — like a switch that turns 'on' when you press a key and 'off' when you release it. The pitch output says which note; this Gate output says 'play now, stop now.'

tip: If your external gear triggers backwards or not at all, switch the gate format — older gear often needs S-Trig, while most modern modular expects V-Trig at 5V or 12V.

show text from manual

A control output that sends a Gate signal — high on Note On, low on Note Off — to trigger envelopes or other events on external devices. Its format can be set to S-Trig, V-Trig 5V, or V-Trig 12V in Utility or the MIDI Control Center to match the connected gear.

Pressure output

This sends out your finger-expression from the keyboard as a control voltage, so you can use how hard or how much you press to open a filter, sweep a sequencer's speed, or shape a sound on external analog gear. Whether it sends pressure or velocity depends on your keyboard mode setting.

tip: You can dial the maximum voltage from 1V up to 10V, but note that not all Eurorack modules can handle 10V — some will clip if the voltage goes too high, so start lower if a destination behaves oddly.

show text from manual

A control output that sends either a pressure (aftertouch) voltage or a velocity voltage depending on Utility>Preset>Press mode. The output voltage range is adjustable from 1V to 10V via Utility>CV/Gate>Pressure Range or the MIDI Control Center, letting you match the sensitivity of external gear.

Clock input

This lets an outside piece of gear be the 'conductor' that sets the tempo. Plug in a clock signal here and the MicroFreak's tempo-based parts (the wobble of the LFO, the speed of arpeggios and sequences) will lock to that outside beat instead of running on their own, so everything stays in time together.

tip: For the MicroFreak to actually follow the incoming clock, set the sync source to 'Clock' in Utility (Sync > Source), and make sure the PPQ setting matches what the sending device outputs. Use a TRS cable if you also want the external gear to start and stop the MicroFreak, not just set the speed.

show text from manual

A 1/8" jack that receives an external timing pulse to synchronize the MicroFreak's LFO, arpeggiator, and sequencer to another device (older synths, drum machines, or modular systems). It supports several pulse-per-quarter-note formats: one pulse per step, 2PPQ, 24PPQ, or 48PPQ, set in Utility or the MIDI Control Center. Using a TRS (stereo-style) cable delivers both clock and start signals; a TS (mono-style) cable delivers clock only.

Clock output

This makes the MicroFreak the 'conductor' for other gear. It sends out a steady stream of timing pulses so an external device speeds up, slows down, and starts in step with the MicroFreak's tempo.

tip: Match the output PPQ format to whatever your vintage device expects (many old machines use 24PPQ, but some use other rates). Use a TRS cable if you want the MicroFreak to also start and stop the connected gear.

show text from manual

A 1/8" jack that sends the MicroFreak's timing pulse out to synchronize older pre-MIDI devices such as vintage Korg and Roland drum machines. It can output one pulse per step, 2PPQ, 24PPQ, or 48PPQ, configurable in Utility or the MIDI Control Center. A TRS cable carries both clock and start signals; a TS cable carries clock only.

MIDI input (1/8" TRS)

This is how another keyboard, computer, or sequencer can play the MicroFreak's sound. Send notes in and the MicroFreak plays them, so it can act as a sound module driven by outside gear. It's best to send only one note at a time if you're also converting to CV outputs, since polyphonic input can behave unpredictably.

tip: You must use the included grey 1/8" TRS-to-5-pin-DIN adapter — a regular TRS cable alone won't connect to standard MIDI gear. Set the MicroFreak's input channel in Utility (MIDI > Input chan) to match the sending device, or set it to 'All' to receive on every channel.

show text from manual

A 1/8" TRS jack that receives MIDI note, controller, and clock data from external MIDI devices. It requires the included 1/8" TRS-to-5-pin-DIN adapter (grey) to connect standard MIDI cables. Notes arriving here have priority over notes played on the MicroFreak's own keyboard or its internal sequencer.

MIDI output (1/8" TRS)

This lets the MicroFreak play and control other synths. Its keyboard, arpeggiator, and sequencer can trigger notes on another instrument, and turning the MicroFreak's knobs can send control messages to tweak external gear. Only one note per chord is sent out, so it's really suited to single-line and control duties over MIDI.

tip: Use the grey included adapter to reach standard MIDI plugs. To send arpeggios/sequences out, enable Arp/Seq MIDI out in Utility; to make the knobs control external synths, turn on 'Knob send CCs' (Utility > MIDI). Set the output channel to match the receiving device.

show text from manual

A 1/8" TRS jack that transmits MIDI note data, knob CC data, and arpeggiator/sequencer notes to external MIDI devices. It requires the included 1/8" TRS-to-5-pin-DIN adapter (grey). When playing a chord, only the last and lowest note of that chord is transmitted via MIDI.

USB type B port

This is the single cable that links the MicroFreak to your computer. Through it the synth sends and receives MIDI, can be powered, and can be edited or backed up with Arturia's free software. It's also handy for portable use — plug it into a phone charger or battery pack and the MicroFreak runs without a computer.

tip: When running on USB power only (like from a power bank), the touch keyboard needs proper grounding to work fully — Arturia recommends the supplied three-pin wall adapter for reliable keyboard response. Use the MIDI Control Center over USB to change how the knobs 'catch' values (Jump, Hook, or Scaled).

show text from manual

A standard USB type B connector that provides both power and MIDI data to and from a computer. It connects the MicroFreak to Arturia's MIDI Control Center software for configuring settings, updating firmware, and managing presets. It can also be powered from a standard USB phone charger (5V, 500mA) or a power bank for computer-free operation.

DC IN power connector

This is where you plug in the wall power. Beyond just powering the synth, this specific adapter grounds the instrument so the touch-sensitive keyboard reads your finger pressure accurately. Using anything else can make the keyboard behave erratically.

tip: Only use the Arturia-provided supply — other adapters can leave the keyboard poorly grounded and unresponsive, and Arturia won't cover damage from unauthorized supplies. Note that plugging in DC power resets the unit, so connect it before you start a session.

show text from manual

The main power input that connects the MicroFreak to a wall outlet using the Arturia-supplied power adapter (internal 2.1 mm, external 5.5 mm). This supply was specifically designed to provide the electrical grounding the capacitive touch keyboard needs to operate properly. If both DC and USB power are connected, DC takes priority, and plugging in DC power resets the MicroFreak.
