I've been at this for awhile and haven't made much progress. The problem is that I just really want to play a single wave on the WAVE channel. In this case, just a sine wave.
I didn't see a setting in the synth or instrument menus to do that, however. Since the wave patterns are cycling, I get clicks which can be quite clearly heard when using a sine-wave as the waves are cycled. Since the sound isn't really changing, the clicks are just getting in the way.
I know you can slow down the speed that the cycling occurs in the instrument menu - is there a way to just turn it off altogether?
