Audio Effects
SousaFX has a number of custom effects such as a dubstep-style lowpass filter, an envelope crossfade that allows loud sounds to be effected differently than soft sounds, a stutter with acceleration, a tremolo with adjustable duty cycle, a one-button looper, dub-style delay sends, and volume automation tied to the kick drum.
Many default effects are from the rnbo guitar pedals package. These effects can be swapped with plugins if desired.
