Chapter 6· Groove OS 2.0 beta
KIT
Play along as you read: the FM-1 beside the text is a working one, running the real Groove OS 2.0, and it follows the part of the page you are reading. Tap a control's name in the text to find it on the panel, and press Start on a Try it card to be shown. Sound stays off until you turn it on.
A KIT track is a whole drum kit on one track: 16 pads on two pages, programmed and mixed as one part. You play the pads from the keys, write beats on a drum-machine step grid, and shape every pad's tune, decay, level and send. A pad can play a built-in drum, a sound from a sound pack, or a recording of your own. Drums take one of your eight tracks, not four.
Making a kit
| Way | What happens |
|---|---|
+ ADD TRACK on TRACKS, then FM KIT or VA KIT | A new kit track, played by the FM engine or by the VA drum models. A built-in kit sits on pads 1 to 8 and pads 9 to 16 are empty. |
| , then a kit, on an empty track | The track becomes a KIT track. On a kit track, taking another kit swaps the sounds under the same beat. While a built-in kit is highlighted in the browser, the keys play its pads, so you can try it first. |
, then KIT (KIT USER) | A kit you built on the SAMPLER, with its sounds on the pads (see Kits from the SAMPLER). |
TRACK menu > ENGINE | Switches an empty track to a kit (a track with notes must be cleared first). |
There are three kits built in: PUNCH (a tight 909 feel for house and techno), DUSTY (soft and round, for lo-fi and hip-hop) and STEEL (for techno tempos, with a metallic ride). Each plays as FM drums or VA drums. EMPTY's drums are the PUNCH kit, as VA drums. A built-in kit fills pads 1 to 8 and leaves pads 9 to 16 empty, so the second page is yours.
Kits from the website
Every sound pack from the website, CORE and the ten genres, brings its own drum kit, free: slots 1 to 8 of the sound pack, one sound per pad (see Sound packs). Once a sound pack is in a bank, PRESETS lists its kit under KITS, by name, after PUNCH, DUSTY and STEEL; 's legend shows where it sits (C01). Its eight drum sounds stay out of the bank's own list, so a sound pack shows just its 24 sounds there; turn the TYPE filter to DRUMS to find a kit's drum sounds one at a time and play one on a sound track. The FM-1 holds up to four sound packs at once, one per letter, so up to four website kits next to the built-in three.
Loading a kit from the Sounds page
On the Sounds page, open a sound pack (See inside): its page plays its kit's 8 pads in the browser. Add to FM-1 puts the whole sound pack, kit and sounds, into the letter you pick: what the letter holds is backed up in the browser first, and the sound pack replaces it (see Loading banks from the website). Right after you install Groove OS, the Install page's Start with CORE card (See sound packs) brings you here.
Then, on the FM-1: select the drum track (or an empty track), turn to KITS, play the keys to hear a kit, and takes it.
Taking a loaded kit copies its sounds into your project, the way a sound track keeps its sound: the project plays the same after you load something else into that bank, and on another FM-1. A loaded kit has eight sounds, so it fills pads 1 to 8 and empties pads 9 to 16. A project holds the sounds of two loaded kits (any number of tracks can use them; the built-in kits don't count). A third says PROJECT FULL: 2 LOADED KITS: put one of the kit tracks back on a built-in kit first, and its sounds make room. A kit made for the VA engine makes the track a VA kit, an FM kit an FM kit.
Kits from the SAMPLER
Kits you build on the SAMPLER (see SAMPLER) are listed in PRESETS as KIT USER, after the others, newest first. Turn to one and it plays; puts it on the selected track, which becomes a kit track with the kit's sounds on its pads, up to 16. The KIT row of the kit menu shows the kit's name (KIT 1). A kit goes on an empty track or on a kit track: a track of another kind with notes says CLEAR THE TRACK FIRST. A pad of such a kit is a sample pad (see Sample pads).
Pads and sounds
A kit has 16 pads on two pages: PADS A holds pads 1 to 8 and PADS B pads 9 to 16. Each plays one of 12 drum sounds, or the track's own sound, or nothing (OFF), or a sound of a loaded kit the project holds, or a recording of your own. The PAD menu names them in short form; a loaded kit's pads show the names the kit gives them (808, C.HAT), and a pad with a recording shows its name. Several pads cut from one recording show its name and a number (R01·2).
| Family | Sounds (as the PAD menu writes them) |
|---|---|
| Kicks | PUNCH kick (P.KICK), BOOM, RUMBLE kick (R.KICK), DUSTY kick (D.KICK) |
| Snares | CRACK snare (C.SNR), DUSTY snare (D.SNR) |
| Others | CLAP, closed hat (C.HAT), open hat (O.HAT), RIDE, RIM, PERC |
On a VA kit, each pad plays the VA drum model of the same name. A recording plays as it is on an FM kit and on a VA kit alike.
Playing the pads
On TRACKS with a kit track selected, the keybed tag says PADS A or PADS B, the page the black keys select on:
- The white keys play the pads: 16 white keys for 16 pads, pad 1 on the first white key and pad 16 on the last, whichever page is showing. Velocity counts.
- The black keys 1 to 8 select a pad of the page showing and sound it: pads 1 to 8 on
PADS A, pads 9 to 16 onPADS B. K1 to K4 then edit that pad. - records pad hits like notes.
and switch the page on the step grid: PADS A 1-8 and PADS B 9-16, as the toast says. The selected pad keeps its place on the other page.
Trying another kit
Turn and move to a kit row (PUNCH KIT, DUSTY KIT, STEEL KIT): the keys now play that kit's eight pads, pad 1 on the first white key and again from the ninth, on any track, so you can hear it before you take it. Your own kit is not touched and nothing is recorded. Move to a sound row and the keys play that sound as notes instead, even on a kit track. takes the kit, keeps yours; either way the keys play your track again. The kit you try always sounds as FM drums; taking it onto a VA kit gives the VA drums. A KIT USER row plays when you turn to it (unless the preview is off in SETTINGS).
The step grid
Press on a kit track, or choose PADS + STEPS ▸ in the TRACK menu (a kit has this one row where a sound track has SOUND ▸ and SEQUENCER ↵: the pads and their steps are one screen). From anywhere else (TRACKS after , MIX, SETTINGS) always brings you back to the grid, and switches the kit's steps back on if they were off; on the grid itself (or in its PAD and KIT menus) switches the kit's steps off (KIT STEPS OFF, the SEQ light goes out) and goes to TRACKS. The hits stay and play on: they are the track's. The header says T1 KIT (the track's number, then KIT), and the keybed tag says STEPS: the white keys are steps here, not pads.
The grid shows the loop: the eight pads of the page showing as rows, the 16 steps of a bar as columns. The playing column is orange, a hit with a chance or condition is struck through, and a ratchet is split. Under the grid are the selected pad's velocities (in orange), its name, its pad number and what plays it (PAD 3 · FM), and its sound's picture drawn in the knobs' colours: the blue wave is TUNE, the green envelope DECAY, the yellow bracket LEVEL. A sample pad draws its recording instead (see Sample pads).
| Control | What it does |
|---|---|
| White keys | The 16 steps of the bar shown. A tap (let go within 300 ms) sets or removes the selected pad's hit. A hold only puts the cursor there: the hit stays as it was, so the PAD menu keeps its hit rows. In the PAD and KIT menus they are the steps of the cursor's bar, even while another bar plays. |
| Black keys | Select the pad of the page showing and sound it. Never writes a hit. |
| Hold + a black key | Set or remove that pad's hit at the cursor step, and select the pad: walk to a step with , then hold and press drums to place them there. The hint line says SEL+PAD: STEP AT CURSOR. On the pattern row (no step yet) it only selects the pad and says SEL+PAD: ON A STEP. The hit takes the kit's VELO, or with KEY the velocity you press the black key with. In the PAD and KIT menus it works the same on the cursor step. |
| , | The previous or next bar (up to four bars show): BAR 2 OF 4. |
| , | The pads shown: PADS A 1-8, PADS B 9-16. |
| Walks the steps; the next bar appears at the bar line. | |
| Hold or + | Select the pad (up or down). Past pad 8 it goes on to the other page. |
TUNE, DECAY, LEVEL, VELO | The selected pad's tune (-12 to +12 semitones; -24 to +24 on a sample pad), decay (14% to 379%, 100 % as designed; a sample pad only shortens, 12% to 100%) and level (0 to 100, one a click), and the kit's velocity (KEY, 40, 64, 80, 100 or 127). |
| Hold , on a sample pad | START, LENGTH, TONE, REVERB. Other pads have no second row. |
| The PAD menu for the cursor step. | |
| Hold | Clear the selected pad's hits (asks: CLEAR PAD 2 STEPS?, and this one cannot be undone). On the pattern row it clears every step (undoable). |
DICE: a new beat on the same kit (one undo). Also the KIT menu's DICE row. |
The hint line on the grid says WHITE KEYS: STEPS 1-16, BLACK KEYS: PADS, SEL: PAD MENU, SEL+PAD: STEP AT CURSOR, HOLD A KEY: CURSOR THERE, OCT: THE BAR and HOME+OCT: PADS A/B, a few at a time.
FOLLOW: while the music plays, the grid shows the bar being played. Touching the cursor, a knob or a step key holds it still for two seconds; lets it follow again at once.

The snare is selected. Tap the third white key: a snare hit lands on step 3.
3A3The pattern row
Move the cursor up to position 0, before step 1: the pattern row. The body shows the hits of the pads on the page showing over all the bars at once. to are LENGTH (in steps, the track's bars), RATE (kit grids always run at 1/16), SWING and VELO. SWING is the project's swing, the same value as the TIME row's on TRACKS: turning it here also swings the sequencer patterns on 1/16. opens the KIT menu.
| Row | What it does |
|---|---|
KIT | PUNCH, DUSTY or STEEL; the sounds change under the same beat, and a question asks first if you have edited pads, anything on pads 9 to 16 included (LOAD DUSTY KIT?). A built-in kit empties pads 9 to 16. OFF turns an empty kit track back into a sound track. A loaded kit or a kit from the SAMPLER shows its name here; choose another in PRESETS. |
VELO | KEY (each hit keeps the velocity you played) or a fixed velocity for the whole kit (40, 64, 80, 100 or 127). |
ALL TUNE | Tune every pad at once, -12 to +12 semitones on top of each pad's own. |
ALL DECAY | Change every pad's decay at once, on top of each pad's own. |
DICE ↵ | DICE, exactly as : a new beat on the same kit over all its bars (one undo), with the kit's DRUM DICE settings. The menu stays open: again rolls again. |
DICE SETUP ▸ | The kit track's own DRUM DICE settings (below). |
CLEAR ALL STEPS | Empty the kit's pattern (asks). Dimmed with no steps (NO STEPS). |
DRUM DICE. A kit track keeps its own settings for DICE, by the kind of drum each pad plays. Turning them changes nothing yet: the next roll uses them. They are saved with the song.
| Row | Values | What it sets |
|---|---|---|
KICK | AUTO, OFF, 1 to 100 % | How busy the kick is. It keeps the bar's first beat unless it is OFF. |
SNARE / CLAP | AUTO, OFF, 1 to 100 % | The backbeat, ghost notes and claps. |
HATS / RIDE | AUTO, OFF, 1 to 100 % | How busy the hats and ride are. The open and closed hat never land together. |
PERCUSSION | AUTO, OFF, 1 to 100 % | The rim and other percussion. |
VARIATION | LAST BAR, REPEAT, EACH BAR | The last bar varies, every bar repeats the same hits, or each bar is rolled on its own. |
ROLL ↵, RESET SETTINGS ↵ | Roll with these, or put them back to AUTO. |
AUTO is DICE as it always was. OFF leaves that kind of drum out of the next beat; with every kind OFF the beat stays as it is (NOTHING TO ROLL). The percentages steer the rules for each kind: they are not the share of steps that get a hit.
A kit's beat is the track's recording, so a kit has no stored patterns A to P: it is as long as the track (1 to 8 bars), and undo, DUPLICATE and CLEAR treat it like any other track. Make it longer ( and F3, G3, A3 or B3, or LENGTH) and the bars it had repeat into the new ones, so a one-bar beat becomes two bars of the same beat; a tap of takes the copies and the length back (UNDO T1 LENGTH).

Hold HOME and press SEQ: DICE rolls a new beat on the same kit.
HOMESEQThe PAD menu
With the cursor on a step, opens the PAD menu: the pad's settings, then the settings of the hit under the cursor. Its header names the pad (PAD 12 and its sound). It reopens on the row you used last, found by its name: the hit's five rows and a sample pad's six come and go, and the rest stay where you left them. On a step with a hit, when you last used one of the pad's own rows, it opens on STEP VELO instead, so the hit's rows are right there.
| Row | Values | What it does |
|---|---|---|
SOUND | OFF, TRACK (the track's own sound), the 12 drum sounds, then the loaded kits' sounds the project holds, then your samples by name | What the pad plays. While the music is stopped, each sound plays once as you turn to it. A sample this FM-1 does not have shows its name in brackets ([KICK]). Choosing another sound resets the pad's sample rows: the whole sample, no attack, loop or tone. |
EDIT ▸ | Sample pads only. The recording on its waveform: START, END, LOOP (the loop point, with LOOP on), ZOOM. previews it and the keys play it; opens REVERSE, LOOP and RESET. | |
FINE | -50 to +50 | Sample pads only. A finer tune on top of TUNE, in hundredths of a semitone. |
REVERSE | OFF, ON | Sample pads only. Plays the recording backwards. |
LOOP | OFF, FWD, PING | Sample pads only. Loops the sound while you hold the pad: forwards, or back and forth (PING). |
ATTACK | 0MS to 2.00S, in steps | Sample pads only. How slowly the sound fades in. With an attack, or a loop, the pad plays while you hold it. |
TONE | OFF, 1 to 100 | Sample pads only. Makes the sound darker, the higher the number. |
TUNE | -12 to +12 semitones (-24 to +24 on a sample pad) | Pitch. |
DECAY | 14% to 379% (31 steps; 100 % is as designed); 12% to 100% on a sample pad | Ring time. A sample pad can only shorten its sound. |
LEVEL | 0 to 100 | The pad's volume, one a click (hold for ten). |
CHOKE | OFF, A, B | Pads in the same group cut each other off: a closed hat cuts the open one. |
REVERB | TRACK, then 0 to 100 % | How much of this pad goes to the shared reverb, so the clap gets a room while the kick stays dry. TRACK follows the track's own send. TRACK sits at the bottom: one click right from it is 0 % (a dry pad), then 1 % a click; left from 0 % is TRACK again. |
DELAY | TRACK, then 0 to 100 % | The same for the shared delay: an echo on the snare alone. |
MUTE | ON, OFF | Silences the pad. |
STEP VELO | up to 127 | This step's velocity. This row and the four below it (CHANCE, RATCHET, FLAM, NUDGE) are listed only when the cursor step has a hit. |
CHANCE | ALWAYS, 95 % down to 5 % in 5 % steps, then 11 conditions | How likely the hit is, and when it plays: FILL, !FILL, 1:2, 2:2, 1:3 to 3:3, 1:4 to 4:4. |
RATCHET | OFF, 2X to 4X | Repeats the hit within its step. |
FLAM | OFF, ON | A quiet grace hit about 15 ms before. |
NUDGE | -11 to +11 ticks | Moves the hit slightly off the grid. |
COPY, PASTE, CLEAR | Copy, paste (asks) or clear the pad's hits (asks; dimmed with none: NO STEPS ON THIS PAD). A copy takes the pad's sample settings along. | |
CLEAR LOCKS | Removes the hit's parameter locks. |
A condition plays the hit on only some passes: 1:2 on the first of every two, 3:4 on the third of every four. FILL and !FILL (not fill) follow the FILL punch-in on PERFORM (see PERFORM).
Sample pads
A pad whose SOUND is one of your samples is a sample pad. It plays on any kit track, FM or VA, through the track's level, sends and track effects. Pick the sample with the SOUND row, or put a whole kit of them on the track from PRESETS (see Kits from the SAMPLER); the SAMPLER is where samples are recorded and trimmed (see SAMPLER).

PROJECT FULL: 32 SAMPLES).
Parameter locks
Hold a step's white key and turn to : that one hit plays with its own TUNE, DECAY, LEVEL and VELO, and the pad's own values stay as they were. Holding the key without turning anything leaves the hit alone. A locked hit shows a cut corner. While you hold the key, the legend and the rings show the hit's values, and the hint says TURN: LOCK IT. An empty step gets its hit as you let go. Locks work on every pad of both pages; on a sample pad TUNE goes two octaves either way and DECAY only shortens, as on the pad.
PAD > CLEAR LOCKS takes the hit's locks off. A project holds up to 64 locks in all (LOCKS FULL: 64 IN USE; clear some to make room). Locks are undoable, one edit at a time, though the newest edit only.
Try it·On the FM-1
Hold the thirteenth white key, the snare's hit on step 13, and turn K1: only that hit changes.
13D5K1Voices
Each pad has one voice, so a new hit cuts the last one on that pad. All kits together use at most six of the 12 FM voices, and VA kits use the VA pool, so a busy beat never steals your bass notes. Sample pads play on the sample voices, not on the FM or VA ones.
Troubleshooting
| What happens | Why, and what to do |
|---|---|
The browser says CLEAR THE TRACK FIRST or the kit row is dimmed | The track has notes of the other kind. Clear it, or use an empty track. |
| The pads sound different while the browser is open | The keys play the highlighted kit or sound. Close the browser () to play your own kit. |
| and do not change the octave on KIT | On the step grid they choose the bar. The pads do not move with the octave. |
| The pads I made are not on the grid | They are on the other page. shows pads 9 to 16 (PADS B), pads 1 to 8. |
| The grid shows only one bar | The track is one bar long. Lengthen it in the TRACK menu. |
| Hits all play at the same loudness | The kit's VELO is fixed. Set it to KEY. |
| The open hat stops when the closed hat plays | They are in the same choke group. Set one pad's CHOKE to OFF or B. |
| A pad is silent | It is muted (MUTE, or a pad mute on PERFORM), its LEVEL is 0, or its SOUND is OFF. Pads 9 to 16 start on OFF. |
| A sample pad shows its name in brackets | This FM-1 does not have that recording. Put it back, or choose another SOUND. |
| A step key did not add or remove the hit | It was held, not tapped: a hold only moves the cursor. Tap it. |
| I moved the cursor and pressed a key, and my hit disappeared | Each white key is one step, wherever the cursor is: the first is step 1, the second step 2 (the tag says STEPS). Pressing the first key again took step 1's hit off. Tap it once more to bring the hit back, and press the key of the step you want. The cursor is only for editing a hit (). |
| The kick is in the reverb | Its REVERB is on TRACK and the track sends. Turn it one click right: 0 %. |
FULL when adding a step | The track holds as many events as it can. Remove some hits. |
KIT STEPS OFF, and TRACKS came up | on the grid (or in its PAD and KIT menus) switches the kit's steps off. The hits stay and play on. Press again, from TRACKS or anywhere else, to open the grid. |
KIT STEPS ARE 1/16 | A kit's grid always runs at 1/16; its RATE cannot change. |
PROJECT FULL: 2 LOADED KITS | The project already holds two loaded kits' sounds. Put a kit track that uses one back on PUNCH, DUSTY or STEEL (or delete it), then take the new kit. |
PROJECT FULL: 32 SAMPLES | The project already uses 32 samples, so a kit from PRESETS that brings more will not go on. Put something else on a track to make room. |
| A loaded kit is gone from KITS | Its bank was loaded with something else. Your projects keep the kit's sounds; load the kit again from the website to pick it for new tracks. |
