PIGEON — complete feature list

0.5.0-beta.1 · THE FINAL BETA for the M-VAVE FM1. This page covers existing features and additions in 0.5. The tutorial and controls explain how to use them.

Instrument and sample storage

• Three tracks: Song 1, a 16-pad drum kit, and Song 2.
• Up to 32 chops per song, plus 16 drum hits: up to 80 assignments across the instrument.
• 500 KiB usable shared sample storage, including encoded audio, waveforms and seek data. Duration depends on format, bitrate and the other sounds loaded.
• Indexed mono MP3 or IMA ADPCM song playback; ADPCM drum hits and USB recordings.
• Eight shared song voices and four additional drum voices. Empty slots stay silent.
• Waveform display, scroll and zoom; two alternate chop layouts sharing source audio.
• Samples and chop settings persist in flash. Patterns share the loaded bank rather than carrying separate copies of its audio.

Chopping and performance

• Independently editable start/end boundaries and first-pass playback point.
• Forward or reverse per chop; semitone pitch and fine tuning in cents.
• Per-chop nondestructive gain and loop crossfade up to 8 ms; browser normalization.
• Envelope controls, held-loop/latch behavior, one-shot playback and choke groups.
• Split/join, copy whole chop, copy settings, duplicate, swap and move assignments.
• Chop-edit undo/redo and reset to original source assignments.
• Hold SEL and a key to audition the ending and loop while held; audition boundary changes immediately while editing.
• FIFO chop queues with repeated entries, selected-entry removal and queue inspection.
• Tap tempo, reference-loop beat count, loop-to-BPM tools and speed sync. Sync follows tempo by changing playback speed and pitch, within 50–200%.

USB sampling and output

• Record incoming digital USB audio to the selected song or drum pad.
• Input level meter, latched clipping warning and remaining recording-time display.
• Immediate or threshold-triggered start; manual stop, seconds limit or bars limit.
• Audition an unsaved take with PLAY; fine/coarse start/end trimming and selected-range audition.
• Confirmed save to the selected destination, retry confirmation and take discard.
• Other songs/pads remain intact when the selected destination is saved.
• Failed, interrupted or overrun recordings are rejected instead of offered as successful takes.
• Input format: mono 16-bit PCM at 22.05 kHz, encoded to IMA ADPCM.
• Record the FM1's stereo master output on a computer over USB audio.

Keep sounds and reclaim space

• On-device Keep selected chops retains marked regions and trims unused source audio.
• Retain in the same song while preserving key numbers, or append to empty keys in the other song.
• Browser selected-chop trimming with encoded-space preview and local undo; retained chops are renumbered consecutively.
• Reclaim obsolete payloads by compacting the live bank.
• Browser chop collections preserve useful regions from multiple source songs independently of the current bank/session.
• Export/import collections, reorder collected sounds, and assemble song banks or drum kits.

Sequencer

• Step grid and piano roll edit the same sequences.
• 1–64 steps per track, with up to four notes per step.
• Live recording and chord-based step entry; stopped/unarmed note toggling.
• Velocity, gate, probability, repeats/ratchets, pitch, step nudge and conditions.
• Independent note length and nudge for notes within a chord; piano-roll duration display.
• Conditional fills and a:b conditions, Euclidean rhythms, DOUBLE/HALF tools and velocity/timing humanization.
• Swing, quantization, step duration/division, tempo timing and sample-end timing.
• Metronome and count-in; sequence undo/redo, automation and parameter locks.
• Custom note timing shares a 128-entry budget with automation/locks; the editor reports a full store.

Patterns and arrangement

• Saved patterns A–D, containing all three tracks' sequences, timing and automation.
• Pattern copy/paste, unsaved-work indication and overwrite confirmation.
• Quantized switching at the next bar or pattern end; change or cancel a pending launch.
• A 16-section arrangement with per-track pattern selections, repeats, section insertion/deletion and captured mutes.
• Complete session backup retains current work, saved patterns, arrangement and sample bank.

Mixer and effects

• Three-track mixer with levels, mutes and FX sends.
• Filter, delay, chorus, reverb, distortion and compression.
• Drum-pad playback controls and choke grouping.

MIDI and accessibility

• USB MIDI note/control integration and MIDI clock synchronization.
• Per-track MIDI channels, OMNI/OFF choices, incoming-note selection and MIDI screen wake.
• Standard firmware screen-reader support through the FM-1 Screen Reader protocol; no separate firmware fork required.
• Page/control/value announcements, WHERE/read-current-screen, transport/recording states, errors and confirmations.
• Emulator browser speech or screen-reader live-region output, repeat-last announcement and remembered preferences.
• Keyboard-accessible virtual keys, buttons and knobs.

Sample loader and session tools

• Browser-local audio import, editing, previews and encoding; Song 1/Song 2 assembly and up to 16 drum hits.
• Append multiple source files to a song, select sections, trim, rearrange and automatically slice remaining keys.
• Chop boundaries, playback point/direction, pitch/cents, gain, normalization, crossfade and matching audition previews.
• Waveform selection, zoom, numeric trim, validated drafts, Apply, reset and workspace undo/redo.
• Bank library and full-session library with summaries and overwrite previews.
• Export/import .kob sample banks, .pigeon complete sessions and .pigeon-chops collections.
