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).

Control buttons

The sequencer allows you to change tempo, mute particular instruments and reset the playhead. <img src="images/lss_function_map.png" height="300" alt="Launchpad Step Sequencer in Logic Pro">
