This is odd...
When I use the CS-80 Osc in my own patches my waveform choice is saw, square, sine, white noise. But... when I look at the preset 0222 "Isaos Whistle" - that uses 2 CS-80 oscs and one of them has the waveform tri selected! If I change its waveform to something else, then I can't reselect tri, but it defo loads with tri selected.
Any thoughts?
