Oberheim | Matrix 12


Oberheim's Matrix 12 is a legendary analog synthesizer from the mid-eighties that is still the king of analog sounds. One of the fattest, roundest, pleasantly analog synthesizers around! It's long been known for creating some of the thickest and best analog pads, sweeps, buzzes, basses and textures. It features Matrix Modulation for extremely wild virtual patching for almost unlimited range of sounds and modulation capabilities!

The Matrix 12 is similar to the Xpander and the lighter Matrix 6. But the Matrix 12 is much fatter and more programmable than either. Every control can have an effect on some other parameter thanks to Oberheim's flexible design. For example, there are 15 types of LFOs and VCAs per voice! And there's plenty of diagrams drawn out on the front panel of the synth to help you figure out some signal routing. This is not a synth for the beginner.

The MATRIX- 12 features one of the most comprehensive MIDI systems available and its interfacing capabilities give you more control than is presently available from other synthesizers in any class.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
