Control mapping may change without notice, but the general schema should remain similar.
NRPN MSB is used for category (panel control, groove edit, fx edit, etc...).
Physical controls send NRPN messages, reception of controls is not implemented yet.
Only FX editing is currently implemented for received NRPN.
For panel controls:
All controls send Pad Mode as NRPN LSB (CC 0x62).
DATA-MSB (CC 0x06) is split into nybbles, control category and control index [Cat:Idx].
Buttons send DATA-LSB (CC 0x26) with state of the button (0x00 or 0x7f).
Encoders send DATA-INC (CC 0x60) or DATA-DEC (CC 0x61). Value is always 0x01 and can be ignored.
CC messages are only sent when the value changes. Once a pad mode and control parameter are selected using NRPN-MSB, NRPN-LSB and DATA-MSB, successive changes to that control will only send DATA-LSB (CC 0x26).
Example
Panel control:
Button push:
Channel 4:
Keyboard Mode:
Shift Button:
PadMode = 0x05
Control = 0x0a
When button is pressed:
| NRPN-MSB | NRPN-LSB | DATA-MSB | Data-LSB |
|---------------------------|---------------------------|----------------------------|--------------------------|
| Status | CC-Num | NRPNCat | Status | CC-Num | PadMode | Status | CC-Num | Control | Status | CC-Num | Value |
|--------|--------|---------|--------|--------|---------|---------|--------|---------|--------|--------|--------|
| 0xB4 | 0x63 | 0x00 | 0xB4 | 0x62 | 0x05 | 0xB4 | 0x06 | 0x0a | 0xB4 | 0x26 | 0x7f |
When button is released (assuming no other controls changed):
| Data-LSB |
|--------------------------|
| Status | CC-Num | Value |
|--------|--------|--------|
| 0xB4 | 0x26 | 0x00 |

It's probably easier to edit FX using ht-cli than to send NRPN directly.
