Industrial Music Electronics (formally The Harvestman) have been in the eurorack scene from th beginning. And the Piston Honda was one of the first digital oscillators that people were very excited about... The mk3 picks up where the mk2 left off and adds an amazing preset system for morphing through your different wavetables and makes the module proper dual oscillator.
In this demo Scott shows off the features of the mk3 and also manages to summon some sort of preacher from hell when demonstrating the wavefolder/shaper section of the module..
