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-frodhes-0.9.4.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /fm1/developer_screen_colour_candidate 63

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

Frodhes 0.9.4 by Leonardo Mirabal (GPL-3.0), a instrument firmware for the FM-1. many developer/diagnostic CCs (2-4, 8-11, 116, 119) live in the release map. Channels: CHANNEL ALL (default, omni) or 1-16 for notes/CCs/PC; clock/start/stop on any channel; USB and TRS MIDI IN (TRS IN switch). Pitch bend: none (pitch bend ignored). Aftertouch: none. Clock: CLOCK EXT (default): tempo follows F8 (USB or TRS), FA/FB start the sequencer, FC stops; INT ignores; no clock out. MIDI out: USB only: keys, chord mode, arpeggiator and sequencer notes on CHANNEL (ch1 when ALL); no CC/PC/clock out except developer query replies. NRPN: none. SysEx `F0 pack7(00 59 cmd len24 body chk) F7`: M-UPGRADE vendor update protocol (installers, hub): cmd 0x11 handshake answers the package identity; F0 22 24 35 7F F7 starts the pulled update. SysEx `F0 22 24 35 7D F7`: soft key: reboot into the bootloader. SysEx `F0 7D 46 4C`: absent: no Felucca editor protocol, no INFO reply. SysEx `F0 43`: absent: no raw DX7 SysEx parser. Identity: vendor identify FM-1_958 for every version (tools/build.py:50), rescue FM-1_000; no editor INFO; USB product "Felucca" (usb.c:274).
