Use 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/yamaha/pss_480.electra-community-clone.fw-unknown.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /pss_480/portamento_i_o 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as pss_480: ask “what can the Yamaha PSS-480 do?” and it reads this map with list_routes. See the MCP guide.
