Synth Glossary

Envelope:: An envelope generator generates a signal that changes through the length of a sound, normally to control the loudness of that sound. An example of its use is to control the volume of a piano sound. It creates a signal that goes from low to high very quickly (the loud bit when the key is pressed), then goes down slowly as the sounds gets quieter. They are also used to drive other parts of the synthesizer, for example the filter....

The Moog Sonic Six is a 2-VCO duophonic synthesizer with a built-in speaker and a 4- octave, 49-note (C-C) keyboard. Each VCO can output sawtooth, triangle, and rectangle (pulse/square) waveforms as well as 2 "waveform generators." A "quality" knob adjusts the width of the rectangular waveform. White or pink noise is also available. The Sonic Six can be set for 3 keyboard modes; high note priority, low note priority, or duophonic. The Sonic Six can also be set to an alternate tuning across the keyboard (different interval between octaves of the keyboard). Portamento rate is controlled by a knob. The envelope section features a basic envelope, with variable control for attack and decay and a switchable release (follows decay) and sustain. It had a single VCF, low-pass voltage controlled filter. Two multimode LFOs are available. Their speed is independently variable and can be controlled by the envelope.
