Industrial Music Electronics Piston Honda mk3

Dual wavetable oscillator with 3-axis morphing and nonlinear waveshaping

20 HP Eurorack module

Piston Honda Mk III by Industrial Music Electronics is a dual wavetable oscillator with three-axis morphing and nonlinear waveshapers. Each of its two independent oscillators scans through a 8x8x8 cube of 512 waveforms via X, Y, and Z axes with dedicated sliders and CV inputs. The oscillators can cross-FM each other via normalled connections, enter external input mode for dynamic waveshaping of incoming audio, and be frequency-linked for massive unison sounds. An 8-slot preset manager with CV morphing enables real-time interpolation between stored states. Custom wavetables can be loaded via microSD card using the WaveEdit format.

Controls & Jacks (40)

  • LINK— Links both oscillators. When active, Oscillator 2 tracks Oscillator 1's pitch and parameters.
  • Bank B— Selects wavetable bank for Oscillator B.
  • Morph A— Morphs through wavetables for Oscillator A. Smoothly interpolates between adjacent waveforms in the selected bank.
  • FREQUENCY 1— Fine frequency control for Oscillator 1. Adjusts pitch within the selected coarse range.
  • Mirror— Waveform mirroring/folding control. Reflects and folds the waveform creating symmetric or asymmetric variations.
  • FM/EXT IN 1— FM modulation or external audio input for Oscillator 1. Depth controlled by FM Depth 1.
  • Bank A— Selects wavetable bank for Oscillator A. Each bank contains a different set of waveforms to morph through.
  • Mirror Attenuverter— Scales the Mirror CV input. Controls external modulation of waveform folding.
