No, stay with PlatformIO VS Code Extension.
But you have to use the pioarduino espressif32 platform!
I don’t think that the ESP32-C6 will support MIDI over USB!
Afaik it can only be used as an USB-CDC device.
Or do you want to use MIDI over BLE ?
Interesting, you have an ESP32-BLE-Remote-Control project on your github, I’ve a look inside to get some ideas … 
This is going off topic. Please check your private messages for further conversation.
No, I would like to link two equipment to each other, a Boss RC-500 pedal which has no BLE (but has Midi) and a M-Vave pedal (which have BLE and Midi) This is why I would like to use a C3 or C6 to make the bridge between the two.
Ok sorry I never use PM before ?!!?
