Oberheim Matrix synthesizers were a product line of
subtractive analog synthesizer
An analog synthesizer () is a synthesizer that uses Analogue electronics, analog circuits and analog signals to generate sound electronically.
The earliest analog synthesizers in the 1920s and 1930s, such as the Trautonium, were built with a var ...

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
voltage-controlled oscillator
A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for fre ...

A voltage-controlled filter (VCF) is an electronic filter whose operating characteristics (primarily cutoff frequency) can be set by an input control voltage. Voltage-controlled filters are widely used in synthesizers.

s. The Matrix-12 is in effect two Xpanders 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 (Matrix-6 without keyboard) and the Matrix-1000 (low cost preset version with extended memory).
