which Oberheim called "Matrix Modulation" as a method of selecting and routing elements that dynamically shape various aspects of the sounds it produces. Matrix synthesizers continue to be popular due to their characteristic late-1980s analog sound and leading patching and filter capabilities. These five products fall into two groups. The Xpander is a six-voice rack-mount synthesizer with

s. The Matrix-12 is in effect two Xpander's plus a keyboard. The second group consists of the Matrix-6 synthesizer, with DCOs, and much more standard filter capability. It had two rack-mount variants, the Matrix-6R and Matrix-1000.
