This effects unit is a golden oldie its one of the studio tools that helped define the sound of the early nineties. While other so-called multi-effects processors only allowed one input signal to be “effected” the Ensoniq DP/4’s four-in, four-out design permitted processing of four parallel channels (multi-processing). There is only one user interface, but up to four different input signals can each go to a separate signal processor. Multiple inputs and outputs also allow for special types of digital effects like vocoding and ducking.
Best of all it sounds lush!
