OG Synth 1.3.1

OG Synth 1.3.1 for the M-VAVE FM-1. The same firmware as on https://ogsynth.cc, kept here in case the site is ever down.

What's new

• F#5, the last black key: with SEL it opens the amp envelope in every engine but FM6 (PHASE: DCA 1, then DCA 2; drum engines: ENV). In the drum engines it works without SEL too.
• RACK: the black keys with print and F#5 are lit faintly and go straight to the drum engine's pages. The white keys still set steps.
• ARP > CHORD on a drum engine: SEL with keys learns the chord again (it used to pick or copy a drum sound).
• Fix: changing the engine from outside (a CZ sound sent from the Manager while on a high page of WAVE) could freeze the FM-1.

Files

• OG-Synth-1.3.1-offline.zip: the install page from ogsynth.cc, running from your own computer. Unzip, then open START-Windows.bat or START-Mac.command (needs Python 3), or run python3 -m http.server 8471 in the folder and open http://localhost:8471/install/1.3.1/ in Chrome, Edge or Opera.
• ogs-1.3.1.fwsc: the firmware package.
• SHA256SUMS.txt

If something goes wrong

• Back to stock: the install page (online or offline) has "Back to the stock firmware", with M-VAVE's FM-1.fwsc from https://www.m-vave.com/download. M-VAVE's own updater, M-UPGRADE, works too, and so does M-Flasher: https://ogsynth.cc/manual#stuck
• FM-1 won't start: if you installed with the m-bootloader option, hold PLAY while switching on for its recovery menu (REC: update mode). Without it, a Mac can put the stock firmware back with the felucca-bsp tools: https://github.com/hugelton/felucca-bsp/tree/main/tools
• Source code (MPL-2.0 part) of this version: tag v1.3.1 of this repository.
