Matrix-12

Oberheim Matrix-12

Released: 1984

MSRP: $4995

Synopsis:

One of the most powerful polyphonic subtractive synthesizers, thanks to its modulation matrix (20 sources max), which includes a Lag processor and 3 (5 point) tracking generators. Architecture Class: Conventional (subtractive).

Ebay Description:

The Oberheim Matrix-12 is a 61 key (velocity and aftertouch sensitive), 12 voice polyphonic, multitimbral analog synthesizer, featuring dual oscillators (with sync and FM), resonant 6-24dB multimode (low pass, high pass, band pass, notch, phase shift) filter, five DADSR envelopes, three LFOs, four ramp generators, 3 tracking generators, lag processor, 100 presets, tape and MIDI interfaces, along with extensive (matrix style) modulation capabilities.
