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-15.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.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /fm1/note/on <note> <velocity>, /fm1/cc/<number> <value>, /fm1/pitchbend <0-16383>, /fm1/program_change <n>.
Limitations¶
Stock firmware V15 (single-timbral, 12 voices). Notes, pitch bend, aftertouch and CC1/2/4/64 on the note channel (Omni by default); the effects on the FX channel (channel 2 by default, no Omni), CC0-23 only. The FM-1 transmits notes only (no CC, no program change, no clock out). The vendor documents no NRPN. Sounds are DX7 voices: a 32-voice bank (`F0 43 0n 09 20 00 …`, 4104 bytes) or a single voice (`F0 43 0n 00 01 1B …`, 163 bytes) is received on any channel; these are presets, handled by the librarian, not driver commands.
Frequently asked questions¶
Which MIDI CC controls the filter cutoff on the M-VAVE FM-1?
CC 0 (0–1), named /fm1/fx/filter/on in SynthHub's map.
How many parameters of the M-VAVE FM-1 can be controlled over MIDI?
SynthHub's map of the M-VAVE FM-1 lists 28 MIDI CC parameters, each with its number, range and a readable name; the full chart is on this page.
Can an AI agent like Claude control the M-VAVE FM-1?
Yes: SynthHub's hosted MCP server knows the M-VAVE FM-1's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
