# MIDI
|
||||
|
||||
## Usage
|
||||
|
||||
First, enable MIDI by adding the following to your `rules.mk`:
|
||||
|
||||
```makefile
|
||||
MIDI_ENABLE = yes
|
||||
```
|
||||
|
||||
There are two MIDI systems in QMK: basic and advanced. With basic MIDI you will only be able to send Note On and Note Off messages using the note keycodes, meaning that keycodes like `MI_OCTU` and `MI_OCTD` will not work. Advanced MIDI allows you to do things like octave shifts, channel changes, velocity changes, modulation, and more.
|
||||
|
||||
### Basic MIDI
|
||||
|
||||
To enable basic MIDI, add the following to your `config.h`:
|
||||
|
||||
```c
|
||||
#define MIDI_BASIC
|
||||
```
|
||||
|
||||
### Advanced MIDI
|
||||
|
||||
To enable advanced MIDI, add the following to your `config.h`:
|
||||
|
||||
```c
|
||||
#define MIDI_ADVANCED
|
||||
```
|
||||
|
||||
#### Sending Control Change (CC) Messages
|
||||
|
||||
If you're aiming to emulate the features of something like a Launchpad or other MIDI controller you'll need to access the internal MIDI device directly.
|
||||
|
||||
Because there are so many possible CC messages, not all of them are implemented as keycodes. Additionally, you might need to provide more than just two values that you would get from a keycode (pressed and released) - for example, the analog values from a fader or a potentiometer. So, you will need to implement [custom keycodes](feature_macros.md) if you want to use them in your keymap directly using `process_record_user()`.
|
||||
|
||||
|
||||
For reference of all the possible control code numbers see [MIDI Specification](#midi-specification)
|
||||
|
||||
#### Example code for using Generic On Off Switches as per MIDI Specification.
|
||||
```c
|
||||
#include QMK_KEYBOARD_H
|
||||
|
||||
extern MidiDevice midi_device;
|
||||
|
||||
// MIDI CC codes for generic on/off switches (80, 81, 82, 83)
|
||||
// Off: 0-63
|
||||
// On: 64-127
|
||||
|
||||
#define MIDI_CC_OFF 0
|
||||
#define MIDI_CC_ON 127
|
||||
|
||||
enum custom_keycodes {
|
||||
MIDI_CC80 = SAFE_RANGE,
|
||||
};
|
||||
|
||||
bool process_record_user(uint16_t keycode, keyrecord_t *record) {
|
||||
switch (keycode) {
|
||||
case MIDI_CC80:
|
||||
if (record->event.pressed) {
|
||||
midi_send_cc(&midi_device, midi_config.channel, 80, ON);
|
||||
} else {
|
||||
midi_send_cc(&midi_device, midi_config.channel, 80, OFF);
|
||||
}
|
||||
return true;
|
||||
}
|
||||
return true;
|
||||
};
|
||||
|
||||
const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
|
||||
LAYOUT(
|
||||
// ...
|
||||
MIDI_CC80,
|
||||
// ...
|
||||
)
|
||||
};
|
||||
```

### Configuration
|
||||
|
||||
Certain values are stored in the `midi_config` struct. This configuration is not persisted to EEPROM. By default, these values are:
|
||||
|
||||
|Configuration |Value|Comments |
|
||||
|-------------------|-----|-------------------------|
|
||||
|Octave |`4` |Corresponds to `MI_OCT_2`|
|
||||
|Transposition |`0` | |
|
||||
|Velocity |`127`| |
|
||||
|Channel |`0` | |
|
||||
|Modulation Interval|`8` | |
|
||||
|
||||
For the above, the `MI_C` keycode will produce a C3 (note number 48), and so on.
