Nice! Stoked to follow this. PIO is really something else, I'm using it for an external ADC and DAC on my own wavetable synth.
Thank you! I agree, without PIO I couldn’t get the pitch as stable as it is now.
Another exciting pico project! What technique do you use to morph between tables? Might need something like that for a LFO thing
Thank you! It's actually quite simple, I'm just fading one table out and the other in. Something like: WAVE_A * (1-CV) + WAVE_B * CV while CV between 0 and 1. I'm uploading the code to my Github when the other CV inputs are working. Cheers!
Sounds good! At what sample frequency do you output your samples to the DAC and how do you avoid/limit aliasing? Is the wavetable band-limited?
I think aliasing is not that much of an issue here because I’m changing the sample rate instead of adjusting the step size in the wavetable.
Please learn the meaning of the words landscape mode.It needs a filter. The sound is way too harsh.
