Synth Glossary

Control input:
An input into part of the synthesizer that allows that bit to be modulated by another part of the synth. For example there is a control input in the amplifier which controls the level of amplification. If a very slow sine wave (an LFO) is patched into this input then the sound will slowly get louder and quieter. If an LFO was patched into the control input of the oscillator instead, then the sound would go higher and lower in pitch....


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.
