The first 48 bytes correspond to potential pad reports, which are encoded with:
- A single-byte
pad index, which occupies the grid position described in the 'index' grid, below. - A two-byte value spanning from 0x4000 to 0x4ffd. If the value does not start with 0x4xxx, then the slot isn't being used, and can be discarded.
Theoretically, analog inputs may touch the remaining slots; but for now, we don't know what they mean.
| Report | Purpose |
|---|---|
| 0x80 | sets button / led brightnesses |
| 0x81 | sets touch strip leds |
Unless otherwise specified, 255 is max brightness and 0 is minimum.
Button 0 refers to the leftmost button over the screen; Button 1 the one directly to its right, and etc. etc.

- The MIDI in and out interfaces for the device carry data to and from the DIN MIDI ports on the back.
- The audio interfaces capture the mic and the line in; and produce sound to headphones and a line out. The lower channels of each are the line.
