sorry, i missed this post - LAST YEAR :-)
2 bounce modes:
first plays the the arp series to the end, and then comes back, playing the end note once only
second mode (i think) plays the series forwards, and then plays everything the other way, so the end note is
triggered twice. i think that's it. have doubt because it doesn't seem like that would be all that good. - ?-
note accumulation: that sounds a bit like this EVM Phrase Arp: as long as at least one note is held, notes
are added, rather than replaced. not sure about note order though.
will your arp firmware be compatible with a v1.3 distribution board and eeproms?
i don't remember how far that revision got with the firmwares. i think i've downloaded most of them.
(i have midi arpeggiators on other things that i can send to ex800)
