# Oberheim Matrix 1000

Matrix 1000, Oberheim @ 20 December 2016

obiematrix1000 “Manufactured in March 1989, this Oberheim Matrix-1000 single-space analog rackmount synthesizer module packs the same six-voice sound engine as Oberheim’s Matrix-6 keyboard synthesizer. It’s loaded with 1,000 beefy matrix-6 patches — 200 for user patches — and you can load additional Matrix-6 patches using system-exclusive MIDI data or a software editor/librarian.

Each of the Matrix-1000’s six voices sports two DCOs (digitally controlled analog oscillators), a lowpass filter, two VCAs, three envelope generators, two LFOs, and two ramp generators. This module works great, is in reasonable cosmetic condition, and has always been used and stored in an entirely smoke-free environment. Turning its volume knob can induce crackling into the audio signal, but the noise disappears when the knob is left alone. As you can see from the close-up photos, there’s a bit of wear and tear on the front panel, but the rack ears are straight and all of the buttons and the display work perfectly well.”
