Moog Polymoog Keyboard polyphonic synth

 

Moog Polymoog Keyboard synthesiser

 

Once again, I am at a loss for words. This is the keyboard (preset) version of the awesome Polymoog and has little except curio value now, although it has had something of a resurgence in parallel with the renewed popularity of Gary Numan – the Vox Humana sound from the Polymoog Keyboard was a staple of his work in the ’80s. Our instrument was bought new by a friend around 1980. He sold an inherited house and had just enough money from the proceeds to buy this and a Korg 800DV. Remember, the value of your investment can go down as well as up…….

The following information is taken from a full-range brochure of the age, with some dodgy drawings of Wakeman, Emerson, Banks, etc on the cover. If I get it together I’ll scan some of the highlights for any trainspotters out there.

The Polymoog keyboard is musically engineered to give you the tonal variety and breadth of expression of a primary keyboard. Fourteen programmed voices give you a variety of characteristic sounds from one keyboard.

The Polymoog Keyboard is velocity sensitive. It allows the same kind of intuitive touch sensitivity as the piano. An individual voltage controlled filter and voltage controlled amplifier for each key lets you play without triggering problems.

Polymoog polyphony is not restricted-either by the number of notes playable simultaneously or by the size of the 71 note keyboard (er….not sure how they work that one out? I would have thought 71 keys would be the maximum playable, n’est pas?).

Synthesizer tonal variety goes right down to voltage controlled oscillators.

Primary keyboard musicality is a keyboard that feels your fingers.

Get them both together in the Polymoog Keyboard.
