Multi-device state tracking #68
Description
Allows splitting some device-bound states into up to 8 different devices, tracking them separately. A dedicated display can also be built specifically for showing device-bound states, which can be tracked in a separate issue.
- Device mode (currently handled via part + port modes, unspecified port modes can choose to fall back to device modes with device IDs)
- Master volume
- Master tuning
- EFX types and parameters
