Since the Quadra essentially contains four independent synths, it's nice to have the ability to independently control how each is affected by incoming pitch bender control. Specifically, Cherry Audio Quadra lets you control on/off and pitch bend depth for all four sections, as well as opening or closing the filter cutoff setting for the Poly Synthesizer and Lead Synthesizer.
