A prototype synth developed by PPG in the 1986-1988 timeframe, and most notable for developing the Virtual analog concept. Like the Fairlight CMI, the Realizer was intended to be able to run a variety of different software packages; Additive synthesis and Wave scanning applications were planned. But the one on which PPG did the most work, and drew the most attention, was their Minimoog emulation. Not only did this duplicate the functions of a Minimoog, it also duplicated the panel layout graphically on a monitor, and at the time it created a sensation.
