Digital waveform oscillator

This is a prototype digital wavetable oscillator of mine.
It takes any VCO or other tone as an input, converts the wave to another digital waveform and spits it back out.
That's the simple way of saying what it's doing.
The more technical way is: An ADC samples an input waveform and converts it into 6 bits of digital information (64 points). Each of these points, according to its amplitude, looks up another 1/64 slice of another waveform stored in ROM.
That ROM data is then converted to 8 bit audio via a DAC.
Electronically, it's converting the input waveform to an address counter and using that as the index into the rom data.
A complete 64 bit address count (perfect reproduction of the rom data) requires a sawtooth wave input scaled correctly, but other waveforms are interesting too.
I've been able to obtain sound that are much like hard sync, chorusing, vocalizations and ring modulation.
But this is only one oscillator. No filters or ring modding at all.

Really nice! Any plans of making a kit?

@moongooat No plans on a kit and I even sold off this one in the video.

Not that it wasn't fun, but I have no modular synth myself to put it in.

It was just an experiment and fun project to try. Thanks for checking out my vids. :)

taking up where Wolfgang Palm left off are ya ??? PPG 3.23 !!!

That would sound great on a vocoder.

I would totally buy a polyphonic synth made up entirely of these oscillators. Say, three per voice, 8 voice polyphony. Add a couple ADSR generators, a VCA, and a Moog ladder filter, and you've got heaven! If I'm not mistaken, since it processes a VCO, you could get away with only having 8 VCO's, then process the signal three times before sending it to the filter, ADSR, and VCA. Cut costs further by using DCO's. Just a thought.^_^
