Dynamic TVF

Cuts off a specific frequency band to change a sounds
brightness, thickness, and other qualities. A wah effect
can be applied by using the volume of the input sound
to vary the center frequency.

Polyphonic Limiter

Compresses signals that exceed a specified volume
level, preventing distortion from occurring.
