DRUM MIX SENSEI

FM-1 KEY MAP ↓

Give the kick some boots. Let ghost notes whisper. Each lane has its own level; your step velocities stay intact. On FM-1: press EDIT.

100% lane level is the original balance. PUNCH adds output gain and attack with soft peak protection. Fresh projects start at PUNCH 50. Turn it down for a gentler mix.

SENSEI HELP · Hold any page button for 0.7 seconds

FX, SELECT, ENVELOPE, LFO, EDIT, GLOBAL, HOME, SAVE, ARP and SEQUENCE each open a help card. Release, then turn PRESETS or SELECT to read the other cards. A short page-button press closes help. Holding SAVE does not save.

Count keys from the left. DJ white 1–8: Roll, Stutter, Reverse, Brake, Filter, Echo, Crush, Gate. White 9–16: Lock, New, Fill, A, B, Drop, Undo, Clean.

Black 1–8: Kick, Snare, Hat, Open Hat, Clap, Perc, Rim, Extra mutes. Black 9–11: Tap, Tape bypass, Undo. STEP and MIX have their own maps, shown in help.

MIX: white 1–8 select a lane; black 1–8 mute. Knobs: Track, Level, Punch, Master. EDIT again opens Beat DNA. HOME knob 4: Master.

GLO → SETUP: four knobs set active key/button brightness, idle button glow, animation and boot splash. GLO again opens MIDI SYNC. Stop, then short SAVE to keep settings with the project. CPU and XRUNS are visible on SETUP. Keys, REC, ARP, ALGORITHM and PRESETS are safe on SETUP/MIDI; PLAY remains live.

Save .cadp projects and their .cadb sample banks together. Project files do not embed your sample audio.

Recorded acoustic hits lead the crate. DUST adds soft saturation and warmth. NOISE blends a soft hiss. LOW PASS softens the top; HIGH PASS thins the drum bus for transitions. CLEAN bypasses the color. On FM-1: press FX twice.

FIRST ROUND / 60 SECONDS TO YOUR FIRST GROOVE

LESS MENU.
MORE MOVES.

01

START BEAT

Pick a style and kit. NEW creates a different two-bar pocket. MUTATE changes a few hits. Swing shifts the offbeats; Human loosens the timing. Space opens a deliberate window for your cuts.

02

PLAY THE KEYS

DJ: eight punch effects and eight direct actions. Drum: 16 individual sounds. Break: rebuild a break from 16 slices. Black keys: eight mutes, Tap, Tape and Undo.

03

LOOP YOUR MOVES

REC captures effect presses and Filter, High Pass, Noise, Rate, Depth and Dust moves. Takes last 1, 2, 4 or 8 bars. Press REC again to overdub. Undo restores the previous take. WAV Bounce renders your beat and recorded effects for a sampler.

SAVEShort press: save while stopped. Hold: help only.

Step Dojo on the FM-1: white keys toggle sixteen steps; the first eight black keys select a lane. Knobs: Track, Bar, Velocity, Nudge. PRESETS selects a step without changing it. ALGORITHM right remixes the selected lane; left undoes. Black key 9 changes the bar, 10 mutes the lane, 11 undoes. HOME returns to DJ performance.

Pocket Lab: clicking a grid cell edits the current part. Track reroll deliberately replaces that track, including a locked track. Undo restores the previous edit. WAV Bounce renders the current part and FX tape; temporary held effects and intro/drop/outro sections are not included.

Every knob has a visible name and value. CLEAN bypasses effects and tape while the beat keeps running. Beat Lock protects your pattern from New and Mutate. Use the editor to lock individual tracks.

WHAT IS INSIDE

76 factory sounds, six styles, sixteen pocket families, twelve factory kits plus three expansion kits, A/B parts, intros, drops, outros, fills, subbass and eight recordable punch effects. Browser and device source share one C audio engine. The browser session does not change your FM-1. Break playback follows tempo by changing speed and pitch.

Cut-A-Dor release 1.2.1. The browser uses the same C sound engine as the firmware. Firmware, recovery and test coverage are on the release page. Installation is always separate. MIDI guide: source, input channel, USB Clock OUT and Continue.
