Sequencer

Since QMK has experimental support for MIDI, you can now turn your keyboard into a step sequencer!

!> 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:

SEQUENCER_ENABLE = yes

By default the sequencer has 16 steps, but you can override this setting in your config.h:

#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
