Oberheim Matrix-12

Oberheim

The Matrix-12 isn’t fat—it’s dense. Every knob bends another parameter, and every patch costs hours.

The Oberheim Matrix-12 is a 12-voice, 61-key, fully analog synthesizer introduced in 1985. It uses Matrix Modulation for virtual patching. Every control can affect another parameter. It provides 15 LFO types and VCAs per voice. It is more programmable and sonically fatter than the Matrix-6 and Xpander. It is not intended for beginners. It is renowned for thick analog pads, sweeps, buzzes, basses and textures—and was called the 'king of analog sounds' in the mid-eighties.

    No dead knobs

    Every control affects another parameter—no dead ends, no defaults.

  2. 1:42
    Virtual patching, not patching

    Matrix Modulation replaces cables with cross-wired intent.

  3. 2:56
    Thickness, not clarity

    It makes thick analog pads, sweeps, buzzes, basses and textures—not clean leads or plinks.

  4. 4:30
    Not for beginners

    It is not for beginners—and its fatness comes at the cost of immediacy.

  5. 5:35
    LFOs as architecture

    Fifteen LFO types and VCAs per voice mean modulation is structural, not decorative.

    King of analog sounds

    It was called the 'king of analog sounds' in the mid-eighties—and still is.

The written brief1 min read

What it is and what it was built for

The Oberheim Matrix-12 is a 12-voice, 61-key, fully analog synthesizer introduced in 1985. It was built for deep sound design, not performance simplicity or accessibility.

How it works, in terms a player would use

It uses Matrix Modulation for virtual patching: every control can affect another parameter. It gives 15 LFO types and VCAs per voice. Its 61-key, 12-voice architecture is fully analog.

What it does better than anything else

It produces thicker, more layered analog pads, sweeps, buzzes, basses and textures than the Matrix-6 or Xpander. Its modulation range is wider and more interwoven.

What it does badly

It does badly for beginners. It offers no simplification, no guided workflow, no presets that teach. Its density overwhelms without commitment.

What people made with it

People made thick analog pads, sweeps, buzzes, basses and textures with it. Its output defined mid-eighties ‘king of analog sounds’ reception.

Who should use it, and who should not

Experienced players who value modulation depth and sonic thickness should use it. Beginners should not. It demands time, attention and tolerance for opaque routing.

Is it worth your time

Yes—if you need thick, complex analog textures and have time to master its depth. No—if you want immediate results or simple programming.

Oberheim XpanderOberheimA keyboardless, six-voice analog synthesizer launched in 1984 and discontinued in 1988. Rack-mounted. Uses Matrix Modulation to route digital control to analog VCOs, multi-mode VCF, and two sequential VCAs. Each voice is independently configurable — including FM via VCO-to-VCO modulation — via multi-patch mode.

Oberheim Polyphonic SynthesizerOberheimThe Oberheim Polyphonic Synthesizer is a series of analog music synthesizers produced from 1975 to 1979. It was the first production synthesizer capable of playing chords. It works by combining multiple SEM modules — each generating one voice — under shared keyboard control and a two-channel sequencer. Its sonic thickness and depth arise partly from random variance between SEM modules. It has no patch memory, suffers tuning drift, and demands high maintenance. Musicians used it for unstable, breathing chordal textures. It suits players who prioritise tactile, variable analog polyphony over stability or recall.

Oberheim OB-8OberheimThe OB-8 gave players twice the programming depth of earlier OB synths—via Page 2—while anchoring Oberheim’s ‘The System’ with the DSX and DMX. It runs on a Z80 CPU, stores 120 patches, and plays eight voices across a 61-note keyboard. It does not hide its age: cassette storage, no effects, and bi-timbral mode cuts voice count in half.

Korg PolysixKorgThe Korg Polysix is a 1981 six-voice polyphonic analog synthesizer designed for affordability through single-oscillator-per-voice architecture, compensated by built-in bucket-brigade-based chorus/phaser/ensemble effects — features that were relatively uncommon at launch and contributed to its accessibility and sonic richness.

It’s analog. It’s gone. It’s unquantified — and that’s the first thing you need to know.
