"extremely rare vintage 1982 Gleeman Pentaphonic analog synth with original owner's manual... serial number 8110047, from the original owner.

The Gleeman Pentaphonic is a five-voice polyphonic analog synthesizer produced in extremely limited quantities (approximately 75 total, including 50 black and 20+ clear) during 1982. It was designed by brothers Al and Bob Gleeman and featured three DCOs for a stable and juicy analog sound. The Pentaphonic was designed to compete against such classics as; the Sequential Prophet-5, Moog Minimoog and Polymoog, and the Oberheim 4-Voice.

In addition to three oscillators per voice, the Pentaphonic has a four-pole lowpass resonant filter with an ADSR envelope, a VCA with ADSR, an LFO, and built-in chorusing (slow or fast). There is also a handy 300-note capacity sequencer on-board for simple real-time recordings that you can play along with. There's also a cool X/Y joystick for controlling pitch and mod effects. Some models, such as this one, also had a Presetter added which gave it 100 patch memories and eight digital waveforms."

"Demo showing synth works correctly."

  1. Why is there random pitch modulation when the sequencer is recording but none while in playback?

  2. If you've heard one in person, you'll probably agree with me that the Gleeman is hands-down the worst sounding poly synth ever made by anybody ever. It's that divide-everything-into-nothing oscillator.
