Thanks, I’ll check that out. My immediate use case is to generate files I can load into Pigments, a software instrument that can load 256 waveforms of 2048 samples each (in one big file), and transition between them. Here’s a screen shot showing one of the wavetables they provide. I was able to generate a similar wavetable using the 2D noise function from Processing.
Yes, I do need to have a periodic source of noise so that you can loop over each waveform without having a glitch at the end. I came across a great solution for this, one that can be more generally applied to any Processing script, it’s just a couple of lines of Java that traverse a circle through the noise space:
