Before I re-invent the wheel, just checking if maybe someone already came up with a simple way to create an OSC that is fast to calculate using PWM output.
I'm not looking into any fancy stuff, but something that is simply fast. ;-) Otherwise I will try to come up with my own. I already got 6 voices of fixed-pitch no-envelope drum-sounds from a single ATmega328 Arduino chip, now I want to check how I could add some SAW sounds. (not pulse) Also without envelope, as I'm using 8-bit and the envelope sounds pretty bad with 8-bits. ;-)
