Synth Glossary

The time taken for a sound to achieve maximum amplitude. Drums have a fast attack, whereas bowed strings have a slow attack. In compressors and gates, the attack time equates to how quickly the processor can change its gain....


This synthesizer was based on the popular Matrix line. The Matrix-6 is basically a stripped down Xpander with a 5-octave, 31-note (C-C) keyboard, which features on and off velocity, as well as channel aftertouch. It features 6-note polyphony and pitch and modulation levers (not wheels) to the left of the keyboard. Each voice has two DCOs (as opposed to the Xpander's VCO), a VCF, three envelope generators (5 stage: Delay, Attack, Decay, Sustain, Release), two ramp generators (simple envelopes), tracking (not just for the keyboard but for remapping any modulation source), portamento and FM controls, three LFOs, and two VCAs. Along with other "Matrix" products from Oberheim, the Matrix-6 features what Oberheim called, "Matix Modulation System", which makes for very flexible and powerful modulation programming. With this much programmability it is unfortunate that the only user interface is a single slider and a keypad.
