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....

Polymoog
Highly popular when it came out, the Polymoog is a preset, polyphonic synthesizer with a 71-note (E-D), touch-sensitive keyboard that is splittable three ways. It features divide-down oscillator circuitry and, therefore, didn't sound as rich as most people wanted a polyphonic analog synthesizer (especially a Moog) to sound. The presets are strings, piano, organ, harpsichord, funk, clav, vibes, and brass. The optional (and expensive) Polypedal board allows you to switch between single and multiple triggering, as well as control the pitch, filter, sustain, and external sync. In addition to a main volume slider, the Polymoog has volume sliders for each of the 3 keyboard sections. It also features a 3-band graphic EQ section, and an extensive filter modulation section, allowing it to be modulated by its own LFO, sample-and-hold, and envelope sliders, with variable keyboard tracking.
