[sdiy] UK meet up, intro, and a wavetable module plan

[Scott Nordlund]

> - 16 or so wavetables of 16 samples each (8-bit is good since the goal is gunge)

16 samples sounds too small to me. You'll only have control over the first 8 harmonics, and all waveforms will be very very buzzy. It's not a bad thing to use longer wavetables (unless there's some technical restriction limiting you to relatively low clock frequencies). You can always mask (or otherwise mangle) the address bits to lower the resolution.
