"Cherry Audio's Pentaphonic synthesizer revives the ultra-rare polyphonic hybrid synthesizer originally developed by Gleeman Instruments in 1981. With fewer than 70 units ever produced, this synthesizer is legendary for its rich tone, distinctive design, and pioneering sequencing capabilities. This emulation faithfully reproduces the lush sound of its digitally controlled oscillator (DCO) and analog-filter architecture while capturing the visual essence of the synthesizer "made to be seen, not just heard."

https://cherryaudio.com/products/pent... Cherry Audio has taken its capabilities to new heights with expanded polyphony, expressive performance, polyphonic and parameter sequencing, and a library of studio-quality effects. Our visual makeover offers a choice of stunning designs inspired by the various looks it sported during its brief existence."

Cherry Audio Pentaphonic: A rare synthesizer masterpiece reborn

video upload by CatSynth TV

"CatSynth presents a deep dive into the new Pentaphonic from our friends at Cherry Audio. This is a recreation of the extremely rare Gleeman Pentaphonic synthesizer, complete with its unique look featuring crystaline transparent knobs and a translucent body. The Pentaphonic was an analog polyphonic synth with a few twists, including three digital oscillators with microcontroller-generated waveforms that were fed into an analog Steiner Parker filter. We explore the emulation of these unique features as well as Cherry Audio's enhancements for modulation, effects, and motion. We also check out a few of the factory and expansion-pack presets.

The Vintage Synthesizer Museum Doc - A "Living Museum" where otherworldly sounds come to life!

video upload by Helium Vision

"In this episode of Helium Vision, we invite you into a world that hums with the strange and the beautiful—the Vintage Synthesizer Museum (VSM). Founded in 2013 by the avid synthesizer historian Lance Hill, this “living museum” exists in a space where the past and present come together to offer an immersive experience into the magical world of sound. It’s not just a museum—it’s a place where visitors and artists can disappear into their work, perform in a unique atmosphere, or learn the art of synthesis.

Initially opening its doors in Oakland the VSM is now nestled in the heart of Los Angeles, this space has since witnessed the presence of many modern visionaries—Damon Albarn, Egyptian Lover and Neurosis, to name a few—each leaving behind their own distinctive imprints.

Come with us, as we step into the otherworldly corners of the Vintage Synthesizer Museum and uncover the tales of the instruments that dwell within.

Gleeman Pentaphonic Vintage Synthesizer Keyboard Bought Serviced For Sale Sold Final Synth Test

video upload by tonetweakers

"Here's a quick systematic test of the Gleeman Pentaphonic black we recently sold.
They also made a model in a see-through case called the The Gleeman Pentaphonic Clear which was identical but lacking the speaker present in the black version. We have one of these in our studio.

This synth had reportedly been fully serviced before we bought it, but it still wasn't fully functional (which is sadly typical these days), so we had to pay our tech for another 7 hours of skilled labor to resolve its problems, and now it's working perfectly and sounding like heaven.

GLEEMAN PENTAPHONIC + TASCAM 38 DEMO

video upload by Synth Tailor Electronics

"Here's another Gleeman Pentaphonic that was restored by the shop. We decided to kill two birds and put in another repair item, the Tascam 38 Reel to Reel 1/2" 8 Track Tape Machine. The audio output is recorded directly to tape. (Tascam 38 is for adam remnant, check out his music/Instagram @adamremnant)

There are only around 50 units ever manufactured by the Gleeman Brothers Al and Bob. Such a truly amazing sounding 5 voice polyphonic synthesizer. This five voice polyphonic synthesizer sounds very large in such a small package and is a hybrid of both analog/digital. Featuring a 300 note Polyphonic Sequencer, "Presetter" preset control switches, X+Y Joystick Pitch and Mod controller, and 100 programmable presets.
Visit my website or email for repairs and restorations for vintage synthesizers, drum machines, outboard gear, and tape machines."

Viewing the the complex waveforms of the Gleeman Pentaphonic

video upload by Vintage Synthesizer Museum

"After posting some pics of the Gleeman Pentaphonic Friday, someone in the comments asked what ‘Comp1’ and Comp2’ were in the oscillator section were referring to. Well, according to the manual: The first two waveshapes are COMPlex 1 and COMPlex 2. These are two new complex waveshapes not usually found on a synthesizer and are included for their unique harmonic qualities. Here, we’re viewing the waveforms with the Korg NTS-2 oscilloscope. We currently have one of these oscilloscopes in the studio. If you’d like to see one of these at each of the mixer sections in the studio, let us know."

Rare Gleeman Pentaphonic

via this listing

"Very Rare.

Serviced by Vintage Synth & Co in Paris.

Everything works perfectly.

The Pentaphonic is a five-voice polyphonic analog synthesizer released in 1982. It was designed by brothers Al and Bob Gleeman and featured three DCOs for a stable and juicy analog sound. The Pentaphonic was in the running against such classics as the Sequential Prophet-5, Moog Minimoog and Polymoog, and the Oberheim 4-Voice. But the Gleeman Pentaphonic (and the Pentaphonic Clear) are extremely rare! Only about 30 Pentaphonics and 20 Pentaphonic Clears were ever made."

Tiago Lemos NM808 x Roland | #808DAY

Note the clear Gleeman Pentaphonic. You can find a studio tour of the Vintage Synthesizer Museum here.

"Tiago Lemos, pro street skateboarder and passionate music fan, turns to hip hop as the soundtrack for his skating, with the 808 at the heart of many hip hop classics.

In collaboration with New Balance to commemorate #808DAY in 2024, the Tiago Lemos NM808 x Roland pays homage to the legendary drum machine with a design that intersects music, skateboarding, and street style. We recently caught up with Tiago and renowned DJ and producer Cut Chemist, to talk hip-hop, kick drums and kick flips in a studio that can only be described as a cavern of sonic treasures."

Update: I asked Lance if he knew how many clear Gleeman Pentaphonics were produced. Here's what he had to say: "Not sure how many Gleeman Pentaphonic Clear's there are. Rumored to be around 25. Funny enough, the guy I bought this one from lived in San Jose, which is just a few miles from where the Gleeman brothers were producing their synths. He told me that the one we have was originally a black one, but when they came out with the clear one, he had them retrofit it into a clear one, so he could wear it as a keytar and walk around with it on stage."

Synth Spotting with Adele - When We Were Young (Live at The Church Studios)

Published on Nov 17, 2015 AdeleVEVO

Wasn't expecting to post this one, but take a look at the vintage synths in the background. You should be able to spot a Solina String Ensemble, Yamaha DX7, Roland Jupiter-6, KORG PS3100, Fender Rhodes and a Moog Minimoog Model D.

They aren't touched, but are just part of The Church Studios. In the video below they appear to have an EMS VC3S and a rare Gleeman Pentaphonic as well as some eurorack gear. Further below a a pic from their Studio 1 with the VCS3 and the eurorack modular.  They definitely have their synths covered.

Rare Vintage Gleeman Pentaphonic Analog Synthesizer - One of 50 Made

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"What can I say? Here is the rarest of the rare Gleeman. Only around 50 made. Rare does not make a synth "good" it just makes it rare. If you ask around you will find that the Gleeman sounds incredible. I have owned two in my life. This is the 2nd. Both in black. They also come in clear, but those are even more rare, but who cares about "rare" they sound incredible and a ton of attention to detail went into their manufacture. The keyboard action feels great, the controls are intuitive. I purchased this directly from the man himself in his garage. It is one of the first two made (I believe).."
