Launchpad Step Sequencer

Command line tool allowing you to use Novation Launchpad as a step sequencer.

How it works

The lss handles bidirectional communication with your launchpad using MiDI protocol. Communication is done using mido (python midi wrapper).

When started lss creates new MiDI source named Launchpad Step Sequencer. This source can be used as input in Logic Pro (or other DAW).

In Logic you may need to select Control Surfaces > Bypass All Control Surfaces to avoid default mode of launchpad.

The sequencer allows you to change tempo, mute particular instruments and reset the playhead.

To install locally run:

pip install -e .

Then start the sequencer by running

lss run --device-type=<DEVICE_NAME>

To list supported devices run:

lss devices list
