- Primary field: offsets 21, encoding
raw_u8(identity). - Confidence: high (3/3 dumps matched, 100%).
- Range: Range 1 ... 3 (capture extremes).
- Sampling: extremes, 2 sample mid(s) (not every step).
- How to set:
- encoded = desired_label
- byte[offset0] = encoded & 0x0F # M7 payload nibbles are 0x00-0x0F
- recompute trailing checksum: CRC-16/ARC over bytes[8:72], pack as four high-nibble-first SysEx bytes at offsets 72-75
- Secondary offsets: 25 (edit/UI state, not the parameter word).
- Checksum nibbles: 72-75 (CRC-16/ARC over offsets 8-71, packed high-nibble-first).
