COSMO Rev FFT Osc Module


The COSMO is an 8HP oscillator module using virtual analog modeling.

Cosmo stands for Composite Sine Modeling Oscillator. It uses a 16-band reverse-FFT algorithm to model the oscillator, waveform and filter.

Output is any bandlimited waveform you can imagine, sine, triangle. square or saw.

It also emulates a 24dB resonant filter by reshaping the component spectrum.

The calculated waveforms include sine, triangle, square and saw.

All waveforms are available as super-wave doubling.

There are separate outputs for bandpass and feedback FM effects.
