A pair of custom broadbands, this units allows to control up to 3 expression jacks / parameter simultaneously and independently, and the range of each can be set by the user via the knobs, it was requested that the first output has an extra toggle for an inverted sweep (change the direction of the sweep based on the input) and have an extra CV out, so from one expression pedal or cv source it could sync up to 6 expression jacks / parameters (connecting both broadbands). With the inverted sweep it could create Fade In / Fade Out from 2 sources or ping pong pan effect.
