Malekko Heavy Industry Richter Anti-Oscillator

Anti-Oscillator is a triangle-core analog oscillator with unique wave shaping capabilities. Like standard analog oscillators, it has an index and linear FM input with an attenuator, and there is also an LFO and oscillator frequency range switch.

Anti-Oscillator is unique to the "Mayhem" output and the Init Wave control that controls its waveform. The Mayhem output produces square waves when the Init Wave is turned to the left, but turning the Init Wave knob changes the waveform, producing special shaping from fat PWM tones to organic, metallic tones. Every waveform has a rich overtone, and the reaction with the filter is vivid.

The Init Wave CV input (the "Ext" jack in the lower right) is routed internally when the Tri output signal is not patched, so when you raise the Wave Env knob, the Init Wave is modulated at the audio rate.
