Based on the same core circuit as this:

http://electro-music.com/forum/post-127356.html#127356

...but driving a clocked random module instead, giving you manually selectable waveforms. The difference to the "synced noise" approach is that the formants don't remain constant when changing frequency, as the waveform is actually played back faster or slower rather than simply being lengthened or shortened (like what happens in the "sync" approach). This is as it should be with wavetable oscs.

Again, the tuning is not super-perfect, sorry.

Here's a greatly simplified version, using a OscD sawtooth oscillator.

Pros: way less mem% and cycles% count, better tuning.
Cons: aliasing kicks in faster when going into higher frequency region.

Interesting: when used in this way, the OscC and OscD sawtooth waveforms perform drastically better then OscA and OscB in sawtooth mode. I suspect they are based on a totally different code.
