Besides being the bully-turned-preppy-Claire's-boyfriend in "The Breakfast Club," Bender allows control of the DCO, VCF, and VCA sections using a controller's pitch bend wheel or joystick.
DCO- Sets the bend depth up to a maximum of one octave up or down.
VCF- Allows control of filter cutoff via pitch bend wheel or joystick. At maximum setting, it covers the entire cutoff range in either direction.
VCA- Allows control of VCA level via pitch bend wheel or joystick. At maximum setting it adds or subtracts 10 db in either direction.
