- # Audio
-
- Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any AVR keyboard that allows access to the C6 or B5 port (`#define C6_AUDIO` and/or `#define B5_AUDIO`), you can hook up a simple speaker and make it beep. You can use those beeps to indicate layer transitions, modifiers, special keys, or just to play some funky 8bit tunes.
-
- If you add `AUDIO_ENABLE = yes` to your `rules.mk`, there's a couple different sounds that will automatically be enabled without any other configuration:
-
- ```
- STARTUP_SONG // plays when the keyboard starts up (audio.c)
- GOODBYE_SONG // plays when you press the RESET key (quantum.c)
- AG_NORM_SONG // plays when you press AG_NORM (quantum.c)
- AG_SWAP_SONG // plays when you press AG_SWAP (quantum.c)
- MUSIC_ON_SONG // plays when music mode is activated (process_music.c)
- MUSIC_OFF_SONG // plays when music mode is deactivated (process_music.c)
- CHROMATIC_SONG // plays when the chromatic music mode is selected (process_music.c)
- GUITAR_SONG // plays when the guitar music mode is selected (process_music.c)
- VIOLIN_SONG // plays when the violin music mode is selected (process_music.c)
- MAJOR_SONG // plays when the major music mode is selected (process_music.c)
- ```
-
- You can override the default songs by doing something like this in your `config.h`:
-
- ```c
- #ifdef AUDIO_ENABLE
- #define STARTUP_SONG SONG(STARTUP_SOUND)
- #endif
- ```
-
- A full list of sounds can be found in [quantum/audio/song_list.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/song_list.h) - feel free to add your own to this list! All available notes can be seen in [quantum/audio/musical_notes.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/musical_notes.h).
-
- To play a custom sound at a particular time, you can define a song like this (near the top of the file):
-
- ```c
- float my_song[][2] = SONG(QWERTY_SOUND);
- ```
-
- And then play your song like this:
-
- ```c
- PLAY_SONG(my_song);
- ```
-
- Alternatively, you can play it in a loop like this:
-
- ```c
- PLAY_LOOP(my_song);
- ```
-
- It's advised that you wrap all audio features in `#ifdef AUDIO_ENABLE` / `#endif` to avoid causing problems when audio isn't built into the keyboard.
-
- ## Music Mode
-
- The music mode maps your columns to a chromatic scale, and your rows to octaves. This works best with ortholinear keyboards, but can be made to work with others. All keycodes less than `0xFF` get blocked, so you won't type while playing notes - if you have special keys/mods, those will still work. A work-around for this is to jump to a different layer with KC_NOs before (or after) enabling music mode.
-
- Recording is experimental due to some memory issues - if you experience some weird behavior, unplugging/replugging your keyboard will fix things.
-
- Keycodes available:
-
- * `MU_ON` - Turn music mode on
- * `MU_OFF` - Turn music mode off
- * `MU_TOG` - Toggle music mode
- * `MU_MOD` - Cycle through the music modes:
- * `CHROMATIC_MODE` - Chromatic scale, row changes the octave
- * `GUITAR_MODE` - Chromatic scale, but the row changes the string (+5 st)
- * `VIOLIN_MODE` - Chromatic scale, but the row changes the string (+7 st)
- * `MAJOR_MODE` - Major scale
-
- In music mode, the following keycodes work differently, and don't pass through:
-
- * `LCTL` - start a recording
- * `LALT` - stop recording/stop playing
- * `LGUI` - play recording
- * `KC_UP` - speed-up playback
- * `KC_DOWN` - slow-down playback
-
- By default, `MUSIC_MASK` is set to `keycode < 0xFF` which means keycodes less than `0xFF` are turned into notes, and don't output anything. You can change this by defining this in your `config.h` like this:
-
- #define MUSIC_MASK keycode != KC_NO
-
- Which will capture all keycodes - be careful, this will get you stuck in music mode until you restart your keyboard!
-
- The pitch standard (`PITCH_STANDARD_A`) is 440.0f by default - to change this, add something like this to your `config.h`:
-
- #define PITCH_STANDARD_A 432.0f
-
- ## MIDI Functionality
-
- This is still a WIP, but check out `quantum/keymap_midi.c` to see what's happening. Enable from the Makefile.
