Krach aus Strom makes noise from electricity and it doesn’t follow any rule!

It is a 26 HP Drum/Percussion/Noise Module with three oscillators/voices.

The first voice forms the tonal body, its OSC can produce up to three sub-octaves.

The second voice is a kick drum generator.

The third voice is a percussion oscillator with an integrated ring modulator and noise source in order to create hat and snare like sounds.

Each voice has an EQ boosting low frequencies turning the potentiometer counter clockwise and boosting high frequencies turning it clockwise. EQ B only boosts low frequencies turning to the left, as this voice mainly generates kick-drum sounds.

Each voice can be triggered individually or all at once. There are also single outs per voice. If you want to have all voices on one output you may use the internal mixer.

Tune A and B do not exactly track 1V/Oct. CV In for Voice C has a small effect on Tune and was made to create subtle frequency modulations via CV.
