This is done via MI_BENDD and MI_BENDU. At the moment the value is
hardcoded and cannot be adjusted (future commit?) and is the max for the
`midi_send_pitchbend` function (up or down).
`MI_BENDD` and `MI_BENDU` both require `#define MIDI_ADVANCED`
MIDI pitch bend was already implemented in `protocol/midi.c`, I merely
added the keycodes to trigger them. :) (thanks to Jack, two years ago
in commit fb4fe52c apparently)
* Added Contra keyboard support
The configuration came from a source distribution of the firmware on the
Contra's official website.
I have also included a simple MIDI keymap. (And it works!)
* Changes to Contra config and README
* Readme has been changed as requested by jackhumbert
* Config has been changed to add the Cartel and Contra names to
the USB configuration.
