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-sloop-2.8.1.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /fm1_sloop/bank_select_latched_for_pc 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as fm1_sloop: ask “what can the M-VAVE FM-1 do?” and it reads this map with list_routes. See the MCP guide.
