First, thank you for implementing the arpeggiator!
It would even further boost the creative uses of this addition if one could freely drag a MIDI sequence onto the device from the arrangement or session view. The MIDI information would then be used as the arpeggiator pattern.
The MIDI input routed into the device would then be arpeggiated according to the note on/offs and pitch relations in the dropped MIDI clip; the pitch relations would be determined by the relations between the first note vs. the subsequent notes in the dropped clip.
