After messing around with the arpeggiator for some time, I feel that I'd like to have a switch that would duplicate the arpeggiated notes at the start and end of the pattern... an example:
pressing C,D,E & F with up/down would then be this sequence: C,D,E,F,E,D,C,D,E... etc.
with duplicating the start and end notes is would be this sequence: C,D,E,F,F,E,D,C,C,D,E... etc.
The reason I want this option is that if the start and end notes are duplicated, then pressing down 4 keys would ensure that the pattern would also fit the time signature of four notes... with the up/down pattern as it is now, holding down 4 keys will give you a 6 note repeating pattern, and not 8 notes which would be nice to be able to achieve.
