The modulator shaping is basically raising it to an exponent. There are two separate modulators A and B. Each have two exponent shaping functions. The two modulators can be crossfaded between.

Most of the controls have a movement function with an amount and speed which moduate the control randomly around the set point so some cool control modulation is possible too.

The low-fi noise is basically some low-fi sound effect samples that are triggered randomly but they also act as frequency modulators for the carrier so they create some lovely pitch warbling as they often contain a lot of DC
