About the Sinulator

The Sinulator is a Eurorack module based on our SineCore Modulator, built in collaboration with West Oakland Music Systems (WOMS). It is an improved version of the SineCore Modulator with +/-1080 degrees of modulation before distortion. There is also an integrated VCA and offset/gain knobs for both the VCA and modulator. The Sinulator can be used as a sine wave shaper, converting either a triangle wave or sawtooth wave into an extremely low distortion sine wave. It can also be used as a wavefolder with up to 6 folds in either polarity, controllable by the VCA CV. Finally, it can be used as an FM modulator with through-zero capability.

How to use the Sinulator


As with all Open Music Labs projects, we encourage tinkering with electronics. The Sinulator has a few patch points that can be used to extend its range.

C14 moved from ground to negative voltage rail to improve noise immunity on the LM13700 current source.
