The Piston Honda Mark III is a dual morphing wavetable oscillator with waveshaping audio inputs and unison detune. The three sliders create a waveform for each oscillator to play from the internal “cube” of 16-bit waveforms (8 waveforms across each axis for a total of 512), morphed at full resolution in all three dimensions with full CV control of each dimension (positive and negative voltages accepted). Each of the oscillators may play a different morphed waveform, with selectable response to the slider controls and CV inputs. The voltage-controlled preset manager stores 8 presets to be recalled at any time, under manual or CV control. The preset manager has a morphing mode that smoothly fades from one preset to another, selectable for “just” the waveform settings, or all knobs on the panel. An orange 128x32 OLED display shows the current waveform for the selected oscillator in realtime, its frequency, and the current preset and wave selection. It also provides menu editing for less frequently used parameters with the nearby rotary encoder.
