Fune

A small music studio for multiple platforms

Overview

Fune runs on M-VAVE keyboards (FM-1, SMK-37) and the M5Stack Cardputer Zero today, with desktop, web and handhelds planned. The same engines, sequencer and pages are on every device.

Status: 0.0.1 Alpha, in development. Song and preset files may still change between builds.

To install on an FM-1 or SMK-37, use the web installer in Chrome or Edge on a computer, over USB.

Features

Multi-platform: one codebase across devices: keyboards and the Cardputer Zero today, with computers, the web and handhelds planned; each device gets its own layout
Seven built-in synth engines, one per track, each with filter, amp, two envelopes and an LFO
Engine SDK: build your own engines in C and add them later, next to the built-in ones
Four ways to write notes: piano roll, step sequencer, drum grid and tracker, plus a song mode that chains scenes
Mixer and effects: two insert effects per track and two shared buses (reverb and delay)
Songs and presets save to the device

Engines

**Retro**Two-oscillator analog voice with sub, noise and sync. Fat basses and leads.

**Phase**Phase distortion on two lines, with DCO, DCW and DCA envelopes shaping the tone.

**Trio**Three chip oscillators with interval, detune and pulse width: chords and leads on one track.

**Lofi**Game-console voice: pulse, sweep, vibrato, arpeggio and noise.

**Organ**Nine drawbars with rotary, vibrato/chorus and percussion.

**Digital**Two-operator FM: ratio, index and feedback, from e-piano to bells and metal.

**Drum**Eight lanes of synthesized drums. Pick a piece per lane, then set tune, decay and click.

Your engineBuild more with the SDK, or add new ones as they come.

The built-in engines and effects, and plugins made by others, are listed in the Fune Library.

Pages

**HOME**All four tracks' patterns at a glance, with the playhead and each track's macros.

**MIXER**Level, pan and sends to two buses per track, with mute and solo.

**TRACKS**Every track's pattern side by side.

**ROLL**Piano roll for note pitch and length.

**STEP**16-step sequencer; the keys are the steps.

**TRACKER**Tracker view: all tracks' notes in columns.

**SONG**Chain scenes into a song; each scene picks pattern A-D per track.

**EDIT**Filter (LP/BP/HP/Notch) and amp for any engine, with the response curve drawn.

FXTwo insert effects per track, from 15 types.

**BUS 1 / BUS 2**Shared reverb and delay, fed by each track's sends.

Before you install on an FM-1

Fune runs only with M-VAVE's own (stock) bootloader. On a modified bootloader it refuses to write anything.
It has been tested on FM-1 units with the earlier flash chip only; units with the newer chip should work but are untested.
Fune is not compatible with Felucca or the custom firmwares derived from it: songs, presets and plugins do not carry over.
To go back, install M-VAVE's official firmware with their updater.
