# Sequencer
|
|
|
|
Since QMK has experimental support for MIDI, you can now turn your keyboard into a [step sequencer](https://en.wikipedia.org/wiki/Music_sequencer#Step_sequencers)!
|
|
|
|
!> **IMPORTANT:** This feature is highly experimental, it has only been tested on a Planck EZ so far. Also, the scope will be limited to support the drum machine use-case to start with.
|
|
|
|
## Enable the step sequencer
|
|
|
|
Add the following line to your `rules.mk`:
|
|
|
|
```make
|
|
SEQUENCER_ENABLE = yes
|
|
```
|
|
|
|
By default the sequencer has 16 steps, but you can override this setting in your `config.h`:
|
|
|
|
```c
|
|
#define SEQUENCER_STEPS 32
|
|
```
|
|
|
|
## Tracks
|
|
|
|
You can program up to 8 independent tracks with the step sequencer. Select the tracks you want to edit, enable or disable some steps, and start the sequence!
|
|
|
|
## Resolutions
|
|
|
|
While the tempo defines the absolute speed at which the sequencer goes through the steps, the resolution defines the granularity of these steps (from coarser to finer).
|
|
|
|
|Resolution |Description |
|
|
|---------- |----------- |
|
|
|`SQ_RES_2` |Every other beat |
|
|
|`SQ_RES_2T` |Every 1.5 beats |
|
|
|`SQ_RES_4` |Every beat |
|
|
|`SQ_RES_4T` |Three times per 2 beats|
|
|
|`SQ_RES_8` |Twice per beat |
|
|
|`SQ_RES_8T` |Three times per beat |
|
|
|`SQ_RES_16` |Four times per beat |
|
|
|`SQ_RES_16T` |Six times per beat |
|
|
|`SQ_RES_32` |Eight times per beat |
|
|
|
|
## Keycodes
|
|
|
|
|Keycode |Description |
|
|
|------- |----------- |
|
|
|`SQ_ON` |Start the step sequencer |
|
|
|`SQ_OFF` |Stop the step sequencer |
|
|
|`SQ_TOG` |Toggle the step sequencer playback |
|
|
|`SQ_SALL`|Enable all the steps |
|
|
|`SQ_SCLR`|Disable all the steps |
|
|
|`SQ_S(n)`|Toggle the step `n` |
|
|
|`SQ_TMPD`|Decrease the tempo |
|
|
|`SQ_TMPU`|Increase the tempo |
|
|
|`SQ_R(n)`|Set the resolution to n |
|
|
|`SQ_RESD`|Change to the slower resolution |
|
|
|`SQ_RESU`|Change to the faster resolution |
|
|
|`SQ_T(n)`|Set `n` as the only active track or deactivate all |
|
|
|
|
