ATEK303 cheat sheet
a line plays · turn the knobs · it moves
v1.1 · GPL-3.0 · github.com/animatek/FM1-Animatek
Quick start
- PLAY starts the pattern.
- K1–K4 cutoff, reso, env mod, decay.
- SEQ a brand-new acid line.
- ENV LFO ARP mutate it; REC undoes.
- Press a key: the line transposes, like on a 303.
- SAVE twice keeps it as a preset with an acid name.
Buttons
| PLAY | run / stop (internal clock, or MIDI clock) |
| SEQ | GENERATE a new pattern (new seed) · playing: at the next bar |
| ENV | mutate TIME (rests, notes, ties) · on the page in view |
| LFO | mutate NOTES (octaves) |
| ARP | mutate SLIDES and ACCENTS |
| REC | undo the last mutation or edit |
| GLO | LOCK: SEQ mutates all instead of a new seed |
| EDIT | step editor on / off |
| HOME | VCF → VOICE → PATT → SEQ; from anywhere else, VCF |
| OCT− + HOME | OPTIONS: colour, MIDI channels, seq notes / clock out, fine tuning |
| FX | effect pages (again: the next one) |
| SAVE | save screen: slot, name, OVERWRITE? NO / YES |
| OCT− OCT+ | octave (OCT− on release) |
| keys | stopped: play the voice (hard = accent) · running: transpose |
8 pages · SELECT · K1–K4
DENSITY, RANGE, ACCENTS and SLIDES regrow the pattern from its seed in real time. SCALE and ROOT change at the output: the line keeps its shape. Up to 64 steps: 4 pages of 16, the page playing on view. Signal: voice → drive → chorus → ping-pong delay (synced) → plate reverb.
Step editor · EDIT
| SELECT · K4 | step (the 16 of the page) · page 1:4 … 4:4 |
| a key | sets the step's note and moves on |
| K1 K2 K3 | gate (REST, NOTE, TIE) · octave (UP/DOWN) · semitone |
| OCT-+K4 | hold OCT− and turn K4: STEPS (1–64) |
| ENV LFO | toggle ACCENT · toggle SLIDE |
| REC · EDIT/HOME | undo · leave the editor |
Presets · 32 slots
SAVE opens the save screen: PRESETS picks the slot, SELECT a new acid name, SAVE stores everything (pattern, voice, effects, tempo, scale, root); over a used slot it asks OVERWRITE? NO / YES. Any other button cancels.
12 factory presets in slots 1–12; a new FM-1 starts on 01. Turn PRESETS: the list opens and loads each preset as the cursor reaches it; while playing it waits for the end of the pattern, like a 303 (NEXT). ENV twice deletes, SAVE saves on that slot, HOME closes (or 6 s untouched).
MIDI
In: stopped, notes play the voice; running, they transpose. Clock, start, stop and continue drive the sequencer. Out (USB): the keys and the sequencer's notes (accent 127); clock out on request. Channels in OPTIONS.
Install · leave · rescue
Install from The Firmware Hub (Chrome or Edge), charged battery, cable straight in. It carries the Felucca update loader: any installer can put another firmware or M-VAVE's back.
Fails to start twice? It drops to a safe mode (PLAY retries, REC updates). REC held at power-on: the chip's update mode.
