Every control on the unit, explained in plain English.
Front panel
Knobs
Control knob 1
A hands-on knob for tweaking the sound while you play. Most usefully it's the filter CUTOFF—turn it down to make a sound darker and more muffled, turn it up to make it brighter and more open. What it controls depends on which of the three banks you've picked with [SELECT].
tip: CUTOFF is the single most expressive knob on the synth—sweep it during a pad or bass note for instant movement. If a knob seems to do nothing, the current sound may not respond to that parameter, or you may need to select a different part.
show text from manual
The first of four assignable real-time knobs. It adjusts whichever parameter is currently active in the group chosen by the [SELECT] button—CUTOFF (in the filter group), MIC REVERB (in the second group), or ASSIGN 1 (in the assign group). In Dual/Super Layer it affects all parts; in Split/16-part mode it affects the selected part; on drum kits it affects the currently selected key.
Control knob 2
Another tweak-while-you-play knob. In its most common role it's RESONANCE, which emphasizes the frequencies right around the filter's cutoff point—a little adds a vocal, nasal edge; a lot makes the sound whistle and sing as you move knob 1.
tip: Resonance and cutoff work as a team: nudge resonance up a bit, then sweep cutoff (knob 1) for that classic squelchy synth sweep. Too much resonance can get piercingly loud, so ride it carefully.
show text from manual
The second assignable real-time knob. Depending on the group chosen with [SELECT], it controls RESONANCE (filter group), MFX CTRL (second group), or ASSIGN 2 (assign group). Its target follows the current mode: all parts in Dual/Super Layer, the selected part in Split/16-part mode, or the selected key on a drum kit.
Control knob 3
In its main role this is ATTACK, which sets how quickly a note fades in when you press a key. Turn it down and notes start instantly and sharply; turn it up and each note swells in gently, like a slow bow stroke on strings.
tip: Dial in a slower attack on pads and strings for a smooth, cinematic swell; keep it fast for punchy basses, plucks, and piano so notes speak immediately.
show text from manual
The third assignable real-time knob. Under [SELECT], it controls ATTACK (filter/envelope group), CHORUS/DELAY amount (second group), or ASSIGN 3 (assign group). It affects all parts, the selected part, or the selected drum key depending on the current mode.
Control knob 4
Its main job is RELEASE, which sets how long a note keeps sounding after you lift your finger off the key. Low settings cut the sound off abruptly; higher settings let notes ring out and trail away naturally.
tip: A longer release makes pads and ambient sounds bloom and overlap beautifully, but too much can turn fast passages into a muddy blur—shorten it for tight, rhythmic playing.
show text from manual
The fourth assignable real-time knob. Under [SELECT], it controls RELEASE (filter/envelope group), REVERB amount (second group), or ASSIGN 4 (assign group). Its target follows the current mode as with the other knobs.
Value dial
Your primary tool for browsing and dialing in — turn it to scroll through sounds or to nudge any setting up or down. It's the quickest way to audition patches one after another once you've picked a category.
tip: Hold [SHIFT] while turning to move through values much faster — great for jumping across a long list of patches instead of creeping one at a time. The [–] [+] buttons do the same job in single steps.
show text from manual
The main rotary encoder used to change whatever value the cursor is highlighting — selecting patches, performances, banks, and editing parameters. Holding [SHIFT] while turning it makes the value jump in larger steps.
[MASTER VOLUME] knob
This is the main loudness control for the whole instrument. Turn it right to get louder, left to get quieter. It controls both what goes to your amp/speakers and what goes to your headphones at the same time.
tip: Always turn this all the way down before powering the JUNO-DS on or off, and before connecting anything — the manual notes you may hear a small pop at power on/off, which is normal. Note this knob does not affect the level going into a computer via USB audio.
show text from manual
Adjusts the overall output level sent to the rear OUTPUT R and L/MONO jacks and the PHONES (headphone) jack simultaneously.
Sliders & faders
[MIC IN] LEVEL slider
If you have a microphone plugged in—for singing, talking, or feeding the vocoder—this slider sets how loud that mic sits in the overall mix compared to what you're playing on the keys. Push it up to hear more voice, pull it down to bury it under the music.
tip: Set the rear MIC [LEVEL] knob first so the mic isn't distorting, then use this front slider for the moment-to-moment balance. Note: the JUNO-DS only works with dynamic mics, not condenser mics.
show text from manual
A front-panel fader that adjusts the volume of the signal coming from the rear-panel MIC INPUT jack, balancing the mic against your keyboard performance. It works alongside the rear-panel MIC [LEVEL] knob, which sets the mic's actual input gain.
[PHRASE PAD] LEVEL slider
The eight pads can play backing beats, recorded patterns, or audio tracks from a USB stick. This slider controls how loud all of that pad-based backing is compared to your live keyboard playing—handy for turning the accompaniment up or down while you perform on top.
tip: Use it live to duck the backing track or drum pattern down during a quieter section, then bring it back up for the chorus—no menu diving required.
show text from manual
A front-panel fader that sets the playback volume of the pads [1]–[8], covering the Rhythm Pattern, Pattern Sequencer, and Audio Player functions that share those pads.
[LOWER] LEVEL slider
When you've split the keyboard into two sounds (left hand vs. right hand) or stacked two sounds together, this slider controls how loud the second/lower sound is. Push it up to make that sound louder, pull it down to quiet it.
tip: When layering two sounds with DUAL, use this against the [UPPER] slider to blend them — for example, keep a bright piano dominant while the pad sits softly underneath instead of both fighting each other.
show text from manual
A volume fader that adjusts the level of the lower part when SPLIT is active, or part 2 when DUAL is active. Its position is reflected by the on-screen LEVEL value for that part.
[UPPER] LEVEL slider
This controls the volume of your main sound — the right-hand sound in a split, the first sound in a layer, or the whole stacked sound when using Super Layer. It's the fader you'll reach for most when balancing your primary voice.
tip: In Super Layer mode this is the only level slider that does anything for the layered sound, so use it as your master volume for that thick, detuned patch.
show text from manual
A volume fader that adjusts the level of the upper part in SPLIT mode, or part 1 in DUAL mode. In SUPER LAYER mode it adjusts the overall layered volume. Its position is reflected by the on-screen LEVEL value.
Display & indicators
SELECT indicators
Little lights that tell you what the four knobs are set to control right now, so you don't turn a knob expecting to change brightness and accidentally change reverb instead. When all three glow together, the knobs are temporarily acting as volume faders for your parts.
tip: Glance at these before grabbing a knob on stage—they're your only quick confirmation of which parameter set is active.
show text from manual
The lit markers next to the [SELECT] button that show which of the three Control-knob parameter groups is currently active. When you hold [SHIFT] and press [SELECT], all three indicators light at once to show the knobs have switched to per-part volume control.
BATTERY indicator
A fuel gauge for battery power when you're playing without the AC adaptor plugged in. Steady light means power is getting low; blinking means change the batteries soon. If you ignore it, the screen will eventually show "Battery Low!" and the instrument stops working.
tip: Only rechargeable Ni-MH AA batteries are supported — carbon-zinc and alkaline cells cannot be used. Continuous battery run time is roughly 5 hours (about 4 if a USB flash drive is connected). Plugging in the AC adaptor always takes priority over batteries.
show text from manual
A status light that reflects the remaining charge of the eight AA nickel-metal hydride rechargeable batteries (if fitted). It lights when the batteries run low and blinks when they need replacing; the reading is only approximate.
Display
Your main window into the instrument — it tells you which sound is loaded, what mode you're in, and what every knob and button is currently doing. Almost everything you set up gets confirmed here, so glance at it whenever you're unsure what's selected.
tip: Hold [SHIFT] + [EXIT] to turn the backlight off, and [SHIFT] + [ENTER] to turn it back on — handy for saving battery power or dimming a dark stage. An "*" next to a sound name means you've edited it but not yet saved.
show text from manual
The LCD screen that shows patch/performance names, banks, numbers, tempo, levels, level meters, effect on/off status, and all editing and menu screens. Its contrast and brightness are adjustable in the SYSTEM settings (LCD Contrast 1–20, LCD Brightness 1–20).
Other
Pitch bend/Modulation lever
Push the stick left or right while holding a note to slide the pitch down or up, like bending a guitar string; it springs back to normal pitch when you let go. Push it forward (away from you) to add a wavering vibrato effect to the sound.
tip: You can do both at once — bend sideways while pushing forward — for expressive lead lines. How far the pitch bends and how much modulation is applied depends on the individual patch's settings.
show text from manual
A spring-loaded controller that bends pitch when moved left/right and applies modulation (typically vibrato) when pushed away from you.
Keyboard (88 keys)
This is what you play. It's a full-size weighted keyboard that feels like a real piano, and it senses how hard you hit each key so louder or softer playing changes the sound. Some keys double as controls: hold [SPLIT] and press a key to set where the keyboard divides into two sounds, and hold [TRANSPOSE] with the octave buttons to shift pitch.
tip: If the feel is too heavy or too light for you, press [KEY TOUCH] and choose LIGHT, MEDIUM, or HEAVY — LIGHT lets you play loud with less effort, HEAVY needs a firmer touch. For finer control, the system menu's Curve Offset and a fixed-velocity option let you dial it in further.
show text from manual
An 88-note Ivory Feel-G weighted keyboard with escapement and velocity sensitivity that generates note and velocity data sent to the sound generator.
Side panels
Knobs
MIC [LEVEL] knob
This sets how strong the microphone signal is as it enters the instrument. Turn it up if the mic is too quiet, down if it's distorting. It's a gain stage, separate from the front-panel [MIC IN] slider that sets how loud the mic is in your final mix.
tip: Set this so the mic sound is clear and full but not distorting when you sing or speak loudly, then use the top-panel [MIC IN] LEVEL slider to balance the mic against your playing. This knob mirrors the "Mic In Level" found in the SYSTEM "MIC IN SETTINGS."
show text from manual
Adjusts the input gain (sensitivity) of the signal coming into the MIC INPUT jack.
Switches & toggles
[POWER] switch
This is the on/off switch. Simple as that — but the order you use it in matters for protecting your speakers from pops.
tip: Always turn the volume down before switching on or off. Power on the JUNO-DS first, then your amp/speakers; when shutting down, turn off the amp/speakers first, then the JUNO-DS. Remember the Auto Off function switches the unit off automatically after a set idle time (default can be disabled in System > Auto Off), and any unsaved edits are lost when power turns off — so save your work first.
show text from manual
The switch that turns the unit's power on and off. Roland recommends turning this unit on first, then connected devices; and turning connected devices off first, then this unit. A brief interval (a few seconds) after switching on is needed for the protection circuit before the unit operates normally.
Jacks & connectors
PEDAL CONTROL jack
Plug in a rocker-style expression pedal here to sweep something continuously with your foot — like volume or filter brightness — while your hands keep playing. You can also plug in a footswitch to trigger a chosen function.
tip: Only use the Roland EV-5 expression pedal; the manual warns other expression pedals can damage the unit. Assign what it controls under the SYSTEM "PEDAL" settings (Control Pedal Assign), and if the pedal behaves backwards, switch Control Pedal Polarity to REVERSE.
show text from manual
Accepts an expression pedal (Roland EV-5, sold separately) or a DP-series pedal switch to control assignable parameters or functions.
PEDAL HOLD jack
This is where you plug in a sustain pedal — press it and notes keep ringing after you lift your fingers, just like a piano's damper pedal. It's dedicated to sustain, so you don't have to assign anything.
tip: If you have a continuous-type pedal, turn on "Continuous Hold Pedal" in the SYSTEM "PEDAL" settings to get half-pedal control for subtle sustain. If notes stop when you press the pedal and sustain when you release, set Hold Pedal Polarity to REVERSE.
show text from manual
Accepts a DP-series pedal switch for use as a sustain (hold) pedal, with optional half-pedaling support.
MIDI IN connector
This lets another keyboard, controller, or computer play and control the JUNO-DS's sounds. Notes and other performance data come in through this socket.
tip: You can have incoming program change/bank select messages switch performances by setting the Performance Control Channel in the SYSTEM "MIDI" settings. If MIDI data flow stops, the display shows "MIDI Offline!" — check that the cable is still connected.
show text from manual
A 5-pin DIN connector that receives MIDI messages from an external MIDI device to play or control the JUNO-DS.
MIDI OUT connector
This sends out what you play and adjust — notes, knob moves, and so on — to other MIDI gear so the JUNO-DS can control external synths or a hardware recorder.
tip: In the SYSTEM "MIDI" settings you can choose whether program change, bank select, active sensing, and edit data are actually sent out. Turn on "Soft Through" if you want messages arriving at MIDI IN to pass straight out again to chain devices. Demo song data is not output here.
show text from manual
A 5-pin DIN connector that transmits MIDI messages generated by the JUNO-DS's controllers to an external MIDI device.
MIC INPUT jack
Plug a microphone in here to sing or talk through the JUNO-DS. Your voice can be run through effects like the vocoder (robot-voice controlled by the keyboard) or auto-pitch, or just have reverb added.
tip: Use a dynamic microphone only — the manual states the JUNO-DS does not support condenser mics. It's a 1/4-inch jack, so you'll need a mic cable or adapter with the right plug. If you hear nothing, check both the rear MIC [LEVEL] knob and the front [MIC IN] slider aren't down.
show text from manual
An unbalanced 1/4-inch phone jack for connecting a dynamic microphone, feeding the vocoder, auto-pitch, and mic-reverb functions.
EXT INPUT jack
Plug in a phone, music player, or other audio source here and its sound plays through the JUNO-DS's outputs alongside what you're playing. Handy for jamming along to a backing track.
tip: Set the playback level on the connected device itself, since this input feeds the mix directly. This is separate from the USB flash drive audio player — use EXT INPUT when the audio is coming from an outside device rather than a USB stick.
show text from manual
An input jack for connecting an external audio player or audio device so its sound is mixed with the JUNO-DS output.
OUTPUT L/MONO jack
This is the main way the keyboard's sound gets out to your speakers, PA, or mixer. Think of it as the 'sound comes out here' cable jack. If you can only run one cable, use this one and you'll still hear everything — just not spread across left and right.
tip: Plug into just L/MONO for a single-cable mono setup (small gigs, one powered speaker). Use both L/MONO and R for true stereo, which matters for patches with wide stereo effects like chorus and reverb. The [MASTER VOLUME] knob controls the level here.
show text from manual
One of two 1/4" (quarter-inch) unbalanced line-level output jacks on the rear panel. Together with the OUTPUT R jack it sends the JUNO-DS's audio signal in stereo to an amp or mixer. If you only connect this L/MONO jack, the JUNO-DS collapses the full left-and-right sound into a single (mono) signal through it.
OUTPUT R jack
This is the second half of the stereo output — the right-hand side of the sound. You use it alongside the L/MONO jack when you want the full stereo picture, so effects and layered sounds spread out properly across two speakers.
tip: Only bother with this jack when you're running in stereo. If you're going mono into one speaker or one mixer channel, leave this empty and use L/MONO alone — plugging in only R will not give you the full sound.
show text from manual
The right-channel 1/4" unbalanced line-level output jack. Used together with OUTPUT L/MONO to send a stereo audio signal to your amp or mixer. It carries only the right side of the stereo image.
PHONES jack
Plug your headphones in here for private practice or to check your sound without disturbing anyone. It plays the same thing that comes out of the main outputs.
tip: Turn the [MASTER VOLUME] down before putting headphones on, then bring it up — the same knob drives both the outputs and the headphones, so it can be surprisingly loud. Using headphones is also the manual's suggested test: if you hear sound in the phones but not from your amp, the problem is your cables or mixer, not the JUNO-DS.
show text from manual
A headphone output jack for connecting headphones (sold separately). Its volume is controlled by the [MASTER VOLUME] knob, the same knob that governs the OUTPUT jacks.
USB COMPUTER port
This is the single cable that connects the keyboard to your music software on a computer. It does two jobs at once: it sends your playing as data the software can record and edit, and it also pipes the keyboard's own sound straight into the computer to record as audio — no extra audio cables needed.
tip: For best audio performance, download and install Roland's VENDOR driver from Roland's website and set System > MIDI > USB Driver to VENDOR (this only takes effect after you power off and on again). If you want the keys to only control your software and NOT trigger the JUNO-DS's internal sounds, set Local Switch to OFF. The [DAW CONTROL] button turns the panel into a control surface for your software. On the 76-key model, you must attach the included ferrite core to the USB cable.
show text from manual
A USB port for connecting the JUNO-DS to a computer with a commercially available USB 2.0 cable. It carries both USB MIDI (note and control data to sync with a DAW) and USB audio (recording the JUNO-DS's actual sound into your DAW). Related system settings include USB Driver (GENERIC or VENDOR) and, for DAW use, Local Switch and the [DAW CONTROL] button.
USB MEMORY port
This is where you plug in a USB stick. It lets the keyboard play backing tracks and audio files, load your own sound samples onto the keys, and save a full backup of all your custom sounds and settings so nothing gets lost.
tip: Format the flash drive in the JUNO-DS first (Menu > UTILITY > FORMAT USB MEMORY) so it creates the right folders — put backing tracks in SONG LIST, samples to import in IMPORT. Get into the habit of backing up your user data here (UTILITY > BACKUP), since edited sounds are lost when you power off if not saved. Never insert or remove the drive while the power is on — the manual warns this can corrupt your data — and never pull it out while the screen says 'Processing....'
show text from manual
A USB port for connecting a USB flash drive (sold separately). It's used to play audio files through the Audio Player, import samples (WAV, 44.1 kHz, 16-bit) via Sample Import, import/export patterns as SMF, and back up or restore the unit's user data.
DC IN jack
This is where the power adapter plugs in to run the keyboard from a wall outlet. It's simply how the instrument gets electricity when you're not using batteries.
tip: Loop the cord through the cord hook so a snagged cable can't yank the power out mid-performance. Note that pulling the adapter out — or unplugging it from the wall — while the power is on will cut the power even if batteries are installed, and any unsaved edits will be lost. Use only the supplied Roland adaptor; others may have the wrong voltage or polarity and can damage the unit.
show text from manual
The power input jack for the included AC adaptor (DC 9 V). A cord hook is provided to anchor the power cord and prevent accidental disconnection. When the AC adaptor is connected to an AC outlet it takes priority over installed batteries.
Other
Ground terminal
This is a small metal screw you can wire to a proper ground point to get rid of that slight tingly, staticky feeling you sometimes get when touching the keyboard or a plugged-in microphone. It doesn't change your sound — it's about comfort and safety.
tip: Only connect it to a genuine electrical ground — never to a water pipe (shock risk), a gas pipe (fire/explosion risk), or a telephone-line ground or lightning rod (dangerous in a storm). Grounding can occasionally introduce a slight hum depending on your setup; if you're unsure how to wire it, ask a Roland service center. If you unscrew the terminal screw, put it back and keep it away from small children.
show text from manual
A screw terminal on the rear panel for connecting the unit to an external electrical ground. It addresses the faint tingling or 'gritty' sensation that can occur when touching the unit, a connected microphone, or nearby metal, caused by a harmless infinitesimal electrical charge.
What it is
Roland's 88-key weighted-action version of the JUNO-DS mobile synthesizer workstation, offering pro-quality sounds, performance tools, and sampling.
The Roland JUNO-DS88 is an 88-key stage and studio synthesizer — the full-size, weighted-key member of the JUNO-DS family (there are also 61- and 76-key versions that share the exact same control panel). Its weighted keyboard is an Ivory Feel-G action with escapement, meaning it tries to feel like a real piano under your fingers. Inside is a large library of ready-to-play sounds Roland calls 'patches' (pianos, organs, synths, strings, brass, drum kits and more), organized into categories you pick with dedicated buttons. Because it can run on eight AA rechargeable batteries as well as the included AC adaptor, it's built to be gigged with and carried around.
What it sounds like depends entirely on what you load: it can be a convincing acoustic piano, a lush pad, a punchy analog-style synth lead, a full General MIDI playback engine, or a stack of layered sounds. Every sound passes through Roland's effects — a multi-effect (MFX) engine with 80 effect types plus separate chorus and reverb — so patches can be clean or heavily processed. On top of the keyboard sounds it adds an arpeggiator, a mic input with a vocoder and auto-pitch effect for using your voice as an instrument, eight rubber phrase pads for triggering rhythm patterns and audio files, a built-in pattern sequencer, and the ability to import your own WAV samples and play them across the keys.
In plain terms, the JUNO-DS88 is a do-everything performance keyboard: pick a sound, split or layer it, add effects, jam over a beat, sing through it, and record short loops — all without a computer. When you do want a computer, it doubles as a USB MIDI/audio interface and a DAW controller.
First session: get a sound out of it
- 01Connect the included AC adaptor to the DC IN jack (or install eight charged AA Ni-MH batteries), and plug headphones into the PHONES jack or connect the OUTPUT L/MONO and R jacks to an amp or mixer. Turn the [MASTER VOLUME] knob all the way down first.
- 02Press the [POWER] switch on the rear panel to turn the unit on, and wait a few seconds for it to start up.
- 03Slowly turn up the [MASTER VOLUME] knob while playing a few keys until you reach a comfortable level.
- 04Make sure the [PATCH/PERFORM] button is unlit — this puts you in Patch mode, where you play one sound at a time.
- 05Press a category button such as [PIANO] or [SYNTH] (these are the [0]–[9] buttons) to choose a family of sounds.
- 06Turn the Value dial to browse through the sounds in that category until you find one you like.
- 07To raise or lower the octave, press the OCTAVE [UP] or [DOWN] button; hold [TRANSPOSE] and press OCTAVE [UP]/[DOWN] to shift by semitones for playing in a different key.
- 08Try the real-time Control knobs: press [SELECT] to choose a group of four parameters (like CUTOFF and RESONANCE), then turn the knobs while playing to change the sound.
- 09To layer or split sounds, press [DUAL], [SPLIT], or [SUPER LAYER] — this switches you into Performance mode automatically.
- 10If you change a sound and want to keep it, press [WRITE] and follow the prompts to save; otherwise your edits are lost when you switch sounds or power off.
How the sound flows
Sound starts in one of two places. Most of the time it starts when you press a key (or move the pitch bend/modulation lever or a connected pedal): those actions are sent to the internal sound engine, which plays back the selected patch, drum kit, or imported sample. The other source is your voice — a dynamic microphone plugged into the rear MIC INPUT jack, whose level is set by the rear MIC knob and can be shaped by the vocoder/auto-pitch effect. Whatever is playing runs through the effects section: a multi-effect (MFX) unit for things like distortion, flanger and amp simulation, followed by shared chorus and reverb. In Patch mode one sound uses one set of effects; in Performance mode you can layer or split up to 16 parts, each able to feed the effects. Alongside the keyboard sound, the eight phrase pads can play rhythm patterns, recorded sequencer patterns, or audio files from a USB flash drive, and the mic input is mixed in on its own channel. All of these streams — keyboard/patch, phrase pads, and mic — have their own volume sliders ([UPPER], [LOWER], [PHRASE PAD], [MIC IN]) so you can balance them. They're then summed and sent to the [MASTER VOLUME] knob, which controls the final level going out the rear stereo OUTPUT L/MONO and R jacks and the PHONES headphone jack. Over USB, the same audio can be recorded straight into a DAW on your computer.
Questions owners actually ask
What's the difference between Patch mode and Performance mode?+
Patch mode (the [PATCH/PERFORM] button unlit) plays a single sound — one patch, drum kit, or sample — across the whole keyboard. Performance mode (button lit) lets you combine up to 16 parts, each with its own sound, so you can split the keyboard between two sounds, layer sounds together, or build complex multi-part setups. Whenever you turn on SPLIT, DUAL, or SUPER LAYER, the JUNO-DS automatically switches into Performance mode.
How do I save my edited sound so I don't lose it?+
Press the [WRITE] button. An asterisk (*) next to a sound's name means you've made unsaved changes. In the WRITE MENU, name your sound and choose a destination in the USER bank, then press [ENTER] to save. Important: in Performance mode, if both a patch and the performance show an asterisk, save the patch first and then the performance — saving the performance first will lose your edited patch. Anything not written is lost when you power off or select another sound.
Why is there no sound coming out?+
Check the obvious first: is [MASTER VOLUME] turned up, are your amp/speakers on and turned up, and are cables connected properly? Try headphones in the PHONES jack to isolate the problem. If keys make no sound at all, check that the 'Local Switch' in the MIDI system settings is set to ON (if it's OFF, the keyboard won't play the internal sounds). Also check that the individual part levels and the 'Master Level' system setting aren't turned down, and that no part is muted.
Can I run it on batteries, and how long do they last?+
Yes. Install eight AA nickel-metal-hydride (Ni-MH) rechargeable batteries — carbon-zinc or alkaline batteries can't be used. On the 88-key model the battery compartment is under a sliding cover on the top panel. Fully charged 1,900 mAh batteries give roughly 5 hours of continuous use (about 4 hours if a USB flash drive is connected). The BATTERY indicator lights when they run low and blinks when they need replacing. Note: if the AC adaptor is plugged into a live outlet, it's always used in preference to the batteries.
How do I use a microphone and the vocoder?+
Plug a dynamic microphone (condenser mics aren't supported) into the rear MIC INPUT jack and set its input level with the rear MIC [LEVEL] knob so it doesn't distort. Use the top-panel [MIC IN] LEVEL slider to balance the mic against your playing. Press [VOCODER/AUTO PITCH] to access the vocoder (which makes your voice into a robotic, keyboard-pitched instrument) and auto-pitch effects; the preset bank holds 10 vocoder and 10 auto-pitch settings.
How do I play beats and loops from the pads?+
The eight phrase pads have three main uses, chosen by the buttons above them. Press [RHYTHM PATTERN] to play built-in drum patterns, [AUDIO] to play audio files (MP3/WAV/AIFF) loaded onto a USB flash drive, or [PATTERN SEQUENCER] to play and record your own multi-track patterns of up to eight measures. Use [TEMPO] or tap the [TAP] button to set the speed, and the [PHRASE PAD] LEVEL slider to set their volume against your keyboard playing.
How do I import my own samples to play on the keyboard?+
Samples must be WAV format, 44.1 kHz, 16-bit. Format a USB flash drive on the JUNO-DS, then on your computer copy your WAV files into the 'IMPORT' folder. Insert the drive, press [SAMPLE IMPORT], choose SAMPLE IMPORT, set the original key and loop options, and import — the sample is saved to internal user memory starting at number 501 and mapped across the keyboard. Recall it later by pressing the [SAMPLE] category button. If memory is full ('Memory Full!'), delete unneeded samples first.
Can I use it with my computer as a MIDI controller and audio interface?+
Yes. Connect a USB 2.0 cable to the rear USB COMPUTER port. You can send and receive MIDI and record the JUNO-DS's audio directly into a DAW over USB. Pressing [DAW CONTROL] turns the keyboard into a control surface for DAW software. For best performance you can download and install Roland's dedicated 'VENDOR' USB driver, then select it in the system settings (the change takes effect after you restart the unit). On the 76-key model a supplied ferrite core must be clipped onto the USB cable; that isn't required on the 88.
