The Minimoog is a monophonic analog synthesizer that was released by RA Moog from 1970-1981, as well as modified and re-released in 2002 as the Minimoog Voyager It was invented by Bill Hemsath and Robert Moog.

The Minimoog can be broken down into three basic parts.
3 oscillators with white and pink noise options. The third oscillator also functions as an LFO. Waveforms available include: Triangle, reverse sawtooth, sawtooth/triangle (only in oscillators 1 and 2. Oscillator 3 has a regular sawtooth), square, and two different width pulse waves. Sounds are then sent to the mixer and the 24dB/oct, 4-pole lowpass filter with cutoff, resonance, ADS envelope generator, and keyboard tracking in order to modify the sound. Finally the sound goes to a VCA with its own ASD envelope. The VCF can also be made to oscillate creating a total of 6 sound sources along with the three oscillators, a noise generator, and a direct line input. Additionally the minimoog has a pitch and modulation wheel.

One of the biggest appeals to the minimoog was its sheer size. It was smaller and more portable than the original modular systems that Moog had come up with earlier; it required no patch cables as its oscillators and voltage controls were built in or hard wired.
Musicians loved its uniqued sonic characteristics which came about from an inadvertent overdrive of the filter and the use of discrete transistors.

The minimoog really changed the face of music.
some of its more notable songs and artist include:
Rush
Yes
Funkadlic/Parliment song Flashlight
Stir It Up by Bob Marley
Kraftwerk
ABBA
Pink Floyd
