A sequencer provides the input for two arpeggiators. This can be supplemented with additional notes from the midi keyboard.

To play it:
_ start the clock
– mix in voice 2 (bass)
_ increase steps for arp 1
_ mix in voice 2 (lead)
_ increase steps for arp 2
_ select an other sequence for endrian melody
_ manipulate the gate length(s)
_ manipulate the ADDR SEQ for gate length(s) and/or velocity(s)

Look at the video for an example.

If you want to customize the sequences, then you need a full version of the Entrian Sequencer.
