I'd like to have easy way to play specific frequency with specific waveform and volume on specific channel. Now I know you can achieve similar result by playing sfx in a loop and just poking values, but this would be easier and could lead to some interesting things (like e.g. digitized voice in pico-8 game via dumping wav file to single frequencies, changing bitrate so it will have lower size, then using Zep's compression algorithm over it).

I second this request!

Yes, more sound controls would be great

yep, this'd be interesting to have

Oh, hi, Terry. Any luck of that Pico-8 port of VVVVVV you're supposed to be making?
