Knobs are used to edit the visible parameters. 

The SEQUENCER buttons are used to set and remove steps of the current 
track.

The BAR buttons can be used to edit more than 16 steps. Up to 4 bars, 
each with 16 steps, can be used per pattern.

The VOICE buttons select the voice and sequencer track to edit. Together 
with the SHIFT button they are used to mute single voices.
