PT-Audio Dual Digital Oscillator

via this auction

"PT-Audio Dual Digital Oscillator is based on DSS (Direct digital synthesis) and is running on a ATMega 328p chip.

Both oscillators share a set of 4 * 8 Wavetables that can be interpolated.
It has 8 modes of operation:

Fractal Saw
Additive asymmetrical wrapper
Multiplying symmetrical wrapper
Bitkiller (subtle)
Phase Slave
And Xor Slaves

pitch tracking is 5 octaves, 1V/oct. And can be offset +5 octaves with the coarse/fine controls. Additionally the pitch can be modified by the pitch mod inputs +/- 5 octaves.

Osc1 can be switched down one octave, and osc2 switched down 8 osctaves.

Osc2 can either follow osc1 or run free, by flipping the link switch.

All CV inputs are 0-5V but the pitch mod that is -5/+5. All inputs are protected against voltages outside that range, but inputting a non expected voltage may result in unexpected behavior."
