The Ensoniq DP Pro released in 1997, was the final effects processor to come out of Ensoniq. It came after the success of the DP/4, DP/4+ and DP/2 processors. Unlike the DP/4 & DP/4+, the Ensoniq DP Pro was a stereo effects processor. Sadly, two channels of processing were not all it lost; it also lost the more intuitive interface of the DP/4 series of processors.
