I am on comparing PCM parts of KORG'z AI synths.
Kinda funny, it seems clear why it is rumoured than one sounds better than another.. I found out, that some chips data lines are tied partly. (8 instead of 16) On X3, two chips used 16bit data bus, and one 8 bit. Is it made for storing compressed samples maybe? Someday, I dump these chips to check it out.
