Trigonometric Shaper

Trigonometric Shaper is a versatile waveshaper that applies regular, hyperbolic, or arc functions to incoming CV or audio. Behind the scenes, a +/- 5 or 10 V signal is mapped to +/- 2 Pi before having the function applied to it. Additional gain or attenuation gain be applied using a simple knob to help find the most useful waveforms.

This is extremely useful for taking regular LFO waveforms and warping them into new shapes. However, you can also do some wild shaping with any audio signal. As an example, if you feed a sawtooth oscillator into this, you can turn it into a sine wave. Cranking up the input gain then folds the sine, while turning down the gain will create discontinuities.
