Synth Glossary

LFO:
A Low Frequency Oscillator. It is similar to a normal oscillator except that it outputs very low frequencies (very slow waves) and is used as a control input into another part of the synth. Examples of its use are to create vibrato or tremolo effects....

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.
