Korg Kronos PolysixEX v2: MIDI CC, NRPN and OSC map¶
The Korg Kronos PolysixEX v2 as named OSC addresses — 40 SysEx commands — ready to use from Claude (MCP), SuperCollider, Sonic Pi, TouchDesigner or any OSC app via osc-bridge.

Not tested on the device yet
This driver comes from documentation or community data and has not been checked on real hardware. If you own one, a quick test and a pull request promoting it helps everyone — see CONTRIBUTING.
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/korg/kronos_polysixex_v2.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 kronos_polysixex_v2: ask “what can the Korg Kronos PolysixEX v2 do?” and it reads this map with list_routes. See the MCP guide.
