I've toyed with the idea of making a wavetable oscillator that'd use
AT90S1200 for reading and interpolating the wavetables on the fly.
Idea was to have analog high frequency VCO to clock the DAC and interrupt
pin on the MCU. The MCU would then read new samples from wave rom,
interpolate them (so you could smoothly fade between different waves) and
output the result ready to be latched to DAC.
