The Matrix 6 was released in 1985, aiming to be a more affordable and smaller polyphonic synthesizer from Oberheim. Classic knob-per-function controls were replaced with a small membrane interface, though the Matrix 6 was still programmable and could store 100 patches plus 50 splits. It was a 6 voice bi-timbral synthesizer with a single low pass filter, 12 digitally-controlled oscillators, 12 VCAs, 3 envelope generators per voice, ramp generators and 2 LFOs. The Matrix 6 had a 61-note keyboard with velocity and aftertouch and full MIDI functionality.
