I guess the NES chip where you have a fixed triangle and noise channel is something like that, but you can alter the other two tone channels to have different waveforms, though only with 4 different settings.


I thought those aren't really different waveforms, but rather the duty cycle. Or is that the same thing? (:

Yes technically it's like pulsewidth at different positions, but as you can't specifically glide on a smooth scale it's probably closer to what people think of as fixed waveforms than, say, a SID is.
