3 Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any AVR keyboard that allows access to certain PWM-capable pins, 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.
5 Up to two simultaneous audio voices are supported, one driven by timer 1 and another driven by timer 3. The following pins can be defined as audio outputs in config.h:
16 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:
19 STARTUP_SONG // plays when the keyboard starts up (audio.c)
20 GOODBYE_SONG // plays when you press the RESET key (quantum.c)
21 AG_NORM_SONG // plays when you press AG_NORM (quantum.c)
22 AG_SWAP_SONG // plays when you press AG_SWAP (quantum.c)
23 MUSIC_ON_SONG // plays when music mode is activated (process_music.c)
24 MUSIC_OFF_SONG // plays when music mode is deactivated (process_music.c)
25 CHROMATIC_SONG // plays when the chromatic music mode is selected (process_music.c)
26 GUITAR_SONG // plays when the guitar music mode is selected (process_music.c)
27 VIOLIN_SONG // plays when the violin music mode is selected (process_music.c)
28 MAJOR_SONG // plays when the major music mode is selected (process_music.c)
31 You can override the default songs by doing something like this in your `config.h`:
35 #define STARTUP_SONG SONG(STARTUP_SOUND)
39 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).
41 To play a custom sound at a particular time, you can define a song like this (near the top of the file):
44 float my_song[][2] = SONG(QWERTY_SOUND);
47 And then play your song like this:
53 Alternatively, you can play it in a loop like this:
59 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.
63 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.
65 Recording is experimental due to some memory issues - if you experience some weird behavior, unplugging/replugging your keyboard will fix things.
69 * `MU_ON` - Turn music mode on
70 * `MU_OFF` - Turn music mode off
71 * `MU_TOG` - Toggle music mode
72 * `MU_MOD` - Cycle through the music modes:
73 * `CHROMATIC_MODE` - Chromatic scale, row changes the octave
74 * `GUITAR_MODE` - Chromatic scale, but the row changes the string (+5 st)
75 * `VIOLIN_MODE` - Chromatic scale, but the row changes the string (+7 st)
76 * `MAJOR_MODE` - Major scale
78 In music mode, the following keycodes work differently, and don't pass through:
80 * `LCTL` - start a recording
81 * `LALT` - stop recording/stop playing
82 * `LGUI` - play recording
83 * `KC_UP` - speed-up playback
84 * `KC_DOWN` - slow-down playback
86 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:
88 #define MUSIC_MASK keycode != KC_NO
90 Which will capture all keycodes - be careful, this will get you stuck in music mode until you restart your keyboard!
92 The pitch standard (`PITCH_STANDARD_A`) is 440.0f by default - to change this, add something like this to your `config.h`:
94 #define PITCH_STANDARD_A 432.0f
96 You can completely disable Music Mode as well. This is useful, if you're pressed for space on your controller. To disable it, add this to your `config.h`:
