Malekko Heavy Industry Richter Oscillator II

The Malekko Heavy Industry Richter series updates the legendary Wiard 300 series to the realm of Eurorack modular synthesizers.

The Malekko Heavy Industry Oscillator II is a powerful oscillator for use in Eurorack modular synthesizer systems. The module features dedicated Fine and Coarse frequency controls, 1V/Oct and exponential CV ins, and dedicated outputs for each waveform: sine, triangle, square, and saw.

Additionally, the module contains a second row of outputs that offer phase-modulated versions of its triangle, square, and saw waves. The phase of each waveform is governed by the Phase control and dedicated CV input. 

The Oscillator II works especially well in combination with the Malekko Anti-Oscillator. An ideal use is using the Oscillator II to FM the Anti-Oscillator, then routing the Anti-Oscillator into the Oscillator II’s Phase Mod input.
