The Harvestman - Hertz Donut mkII

The Harvestman - Hertz Donut mkII is a voltage-controlled dual digital oscillator with totally unique dirty digital waveforms. You will forget the traditional waveforms very easily, and also the concept of "clean" wavetable synthesis. However, thanks to the square and ringmod outs, the module is deeply rooted into and analog modular system too.

The Harvestman - Hertz Donut mkII - Dual digital oscillator with internal modulation bus. Voltage-controlled waveform discontinuity, internal pitch tracking with several lag settings. Dedicated square wave outputs, and a multi-purpose gate/XOR ringmod output.
