MONO2K
Six mono machines for the M-VAVE FM-1. A Monomachine-style synthesizer firmware: six tracks, each one machine, a 64-step sequencer with parameter locks, trig conditions and ratchets, and a lofi bus that breaks the sound beautifully.
- Custom firmware
- Stable
- Medium brick risk

MONO2K 1.4.2 for the M-VAVE FM-1: a calm screen, a cleaner FILT, a steadier FM-1.
A calm screen: pages and values change at once, nothing flashes on an action. GLO > SET > MOTN GLTCH brings the glitches back. The splash is the same.
FILT: one curve, moving with the envelope as the track plays; page 2 laid out on even gaps, with a dot riding the envelope. A line now divides the stage's two halves.
Steadier on the FM-1: the two processors share the tracks evenly (the heaviest patterns need about a tenth less time) and the screen waits for the sound when they are busy. The sound is the same, bit for bit.
Your patterns load as they played.
- File:
mono2k-1.4.2.fwsc, identity FM-1_980, SHA-2564a073670802f3751a5dfaa6d8e9289a5a0b8fd2ee7363e72e4665c8e50cc9b50(the same file as the installer's). - Install: from the FM-1 Firmware Hub or the installer page, over USB in Chrome or Edge. Coming from 1.x, your patterns stay.
- Leave it: install any other firmware as usual; MONO2K starts its update loader (Felucca's). Holding OCT− while switching on always reaches the updater.

Getting started
From the project's README ("On the FM-1"):
- What it keeps. MONO2K saves into its own store, the last 128 KiB of the FM-1's data area (0xC0000–0xE0000): one project of 64 patterns and its sound library. It does not read the projects, presets or samples of other firmwares, and its first save overwrites whatever another firmware kept in that area. Back up with the firmware you are on before you switch.
- Back up MONO2K. The Patch Editor reads the FM-1's store over USB (Chrome or Edge) and saves it as a .m2ks file; it writes one back the same way.
- Leave it. Install another firmware as usual (the FM-1 Firmware Hub, or its maker's installer): MONO2K starts the new package's update loader, as Felucca does, whose loader it carries.
- USB. It shows up as a MIDI device named "MONO2K FM-1" and answers the identity FM-1980. While it updates, the update loader shows up as "Felucca Update", the loader being Felucca's.
- Rescue. Hold OCT− while switching on: the FM-1 starts the updater only and waits for a package over USB.
