Still has nobody else here experienced this issue? Because it's created technical problems at every performance I've used it in this far and I'm starting to get worried. Over on the "DSI Prophet 8 and rev 2" Facebook page one other person said he's been having the same issue (Maj 3rd, not octave). This is otherwise the best synth I've ever played, I can get past the other glitches but this is pretty horrifically unusable currently. Going to hit a series of seventh chords through some jazz changes and having them all be harmonized up a major 3rd is...concerning to say the least. Also when knob tweaking live (I don't even risk changing osc freq live due to this issue) the best way to salvage the performance is to move to a new patch and back to the original, but that eliminates any live tweaking I did...hopefully this gets figured out because I play live a lot and it's not reliable at all. I'd say I can't go 15 min without it happening.
