[sdiy] Frequency multipliers

[Liam Daly]

wavefolding seems like a good trick here. the mfos oscillator utilizes both of the concepts that aaron mentioned, i.e. wavefolding and tri-sine conversion, in a neat little package. take a look at page 2 of that schematic and think about what would happen if you fed a tri into U4-A instead of a sawtooth.
