Synth Glossary

Analog Synthesis:
This term is normally used to refer to the tradional synthesis model used by analog synthesizers in the 1970s. It is also known as subtractive synthesis. It involves oscillators, the outputs of which are mixed together and fed into a filter (where certain frequencies are subtracted) after which they are fed through an amplifier. The amplifier and filter are normally also driven by envelope generators....

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.
