There are 2 repositories under step-sequencer topic.
The step sequencer allows you to create a repeating sequence of tones and to change the resulting tone sequence with the buttons and potentiometers. It supports the MIDI protocol and has a DIN connector. This allows you to use the step sequencer together with other instruments or use it as an input for software instruments in a Digital Audio Workstation (DAW). For the seccond approach you might need to use a MIDI to USB cable.
