Version 1.01
1. The sustain pedal now latches the arpeggiator when the arpeggiator is enabled. In
other words, if you hold down the sustain pedal while the arpeggiator is engaged,
the arpeggiation pattern will continue to play until you lift your foot off the pedal.
Note that in this situation, notes will not sustain as they normally do until you turn
off the arpeggiator.
