Oberheim Matrix-12 12 Voice Polyphonic MIDI Synthesizer

   0 reviews  -  2011 views

    The Oberheim MATRIX-12 12-Voice Polyphonic MIDI Synthesizer is based on the same revolutionary technology as its predecessor, the Oberheim XPANDER, the MATRIX-12 features twelve powerful, independently programmable Voices and an elaborate control system for playing them.

    The MATRIX-12 is actually more than two XPANDERs, and the addition of a five octave, Velocity and Pressure sensitive keyboard plus two on-board modulation levers allow for the addition of even more programmable functions. 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.

    Like the sound-producing capability of the XPANDER, the MATRIX-12 Voice utilizes a 15-Mode Voltage Controlled Filter, five Envelopes and five Low Frequency Oscillators as well as a Lag Processor, three Tracking Generators and four Ramp Generators to provide you with all the ingredients for sound creation. All of this is interlaced by the Matrix Modulation™ System for the greatest of flexibility in modulation control. And the MATRIX-12#s twenty-four Voltage Controlled Oscillators (two per Voice) with waveforms that can be selected individually or combined are the secret to its warm, rich sound.

    Each of the MATRIX-12's Voices is completely independent and each can be programmed to play a different sound. They can be grouped polyphonically into Zones or operated independently, from the Keyboard and MIDI simultaneously. All of the functions at your command are easily viewed on the MATRIX-12's three 40-character fluorescent displays, even under poor lighting conditions.

    The MATRIX-12 is a very serious instrument. And you no doubt paid serious money when you purchased it. This manual will provide you with some serious information and we recommend that you read this document in its entirety. It was written to provide you with all the information you will need to operate and interface your MATRIX-12. We encourage you to experiment, or you'll never know what you might discover.
