How do you control it?¶
Find the MIDI ports, then start the bridge with this driver:
osc-bridge detect # prints the ready-to-run line for what is plugged in
osc-bridge run --device devices/m-vave/fm-1.vendor.fw-ghoulbox-2.3.2.json --out-port <N> --in-port <M>
Then send OSC to 127.0.0.1:7777, for example:
From Claude or any MCP client, the osc-bridge mcp server exposes this driver as fm1: ask “what can the M-VAVE FM-1 do?” and it reads this map with list_routes. See the MCP guide.

Limitations¶
GHOULBOX 2.3.2 by jasonpersinger (GPL-3.0), a instrument firmware for the FM-1. CC map rewritten; Program Change and MIDI learn removed; SEQ OUT ON: each track on its own channel. Channels: Felucca 1.4.1 routing (block CH1-4 -> tracks 1-4). Pitch bend: Felucca (RPN0). Aftertouch: Felucca (mod source). Clock: Felucca clock in. MIDI out: 'SEQ OUT ON' sends each track on its own channel. NRPN: none. SysEx `F0 7D 46 4C`: Felucca editor; FM6 bank 74-77 (fm6_vbank.c identical to Felucca); INFO 'FELUCCA v1.4.1 GB\<ver>'. SysEx `F0 43`: no raw DX7. SysEx `F0 00 32 45 00 00 00 40 7F F7`: vendor update identify query (00 59 11 packed); update protocol kept. Identity: vendor identify FM-1_9XY; editor INFO 'FELUCCA v1.4.1 GB\<ver>' (list version 2.3.2; latest tag ghoulbox-v2.4).
