Due to the low latency of lalelu_drums (around 20ms, see Log #17 for a measurement), it is possible to play along with other musicians. In this log entry, a demonstration is given, in which lalelu_drums is used to play a bass line for a pop song, performed together with a drummer and a singer.

The pitches of the notes of the bassline are predefined for the selected song (No roots, Alice Merton), but the trigger times are solely generated from the live video stream of the player.

Thanks go to Andreas for singing and video editing, Bent for drumming and Jonas for camera handling. There is also a full-length video available here.
