Dual Yusynth Filters Demo

YouTube via davidryle | Feb 27, 2011 |

"Yves Usson's Minimoog transistor ladder filter module from a Bridechamber.com kit.
Two different component builds. One with the 2210 transistor arrays and the second with three pairs of matched BC547 NPN's. They sound similar but the calibrations may be a little off in relation to one another. The 2210 transistor array sounds smoother to me. The discrete transistor pairs sound thicker in the resonant ring. Probably due to the slightly less matched pairing. All caps are within 1% in the ladder but each module contains different vendor parts for the capacitors.
The front panels are different too. The left module is silk screened graphics, and was bought used. The right module was engraved with a high speed CNC milling machine in my shop. The font is not the best but I plan to improve on it for future projects.
Running these modules in parallel is really interesting. I have another video I made of that. I'll post it later. I can't really say whether the clones are truly close to a Minimoog filter or not. I don't own one and it's been years since I've played one. Also there are different makes of Minimoog so the filters all don't sound the same exactly anyway. Regardless, I think these filters sound very good and am pleased with the build. Yves is quite a good designer and I feel fortunate to be able to use his design here.
The left module with the 2210's is a component and PCB kit from Bridechamber.com. The right module was just the PCB from them but I rounded up all the components. Thanks to Scott Deyo for rushing these kits out to me. This was a real fun project and great learning exercise."

"Trying to make something metallic. Not quite what I wanted, but sounded interesting nonetheless."

Buchla 291e Resonance II

"Spent some time trying to incorporate white noise in a patch. This is white noise into the 291e, fed back, then AM'd using the 261e, then RM in the 285e. 281e in quadrature handles the morphing. 255 handles note lengths."

"Buchla 200e (223e, 259e, 261e, 266e, 225e, 250e, 281e and 292e). Buchla track in one take, backing track overdubbed."

A Radiophonic Weekend - Bristol

Update: The event is in April, not March.

Two day event via Cube Cinema, Saturday April the 2nd and Sunday the 3rd.

"Day one of a weekend of special events, performances, screenings and more - dedicated to the output and legacy of the one and only BBC Radiophonic Workshop.

With their often primitive hand built devices, tape loops and early synth explorations, the workshop brought the sound of electronic weirdness out of the realms of academia and into the home, re-adjusting the ears and minds of an entire generation in the process. As interest in their oddly British, and often somewhat crackpot approach to electronic experimentation grows, and as many of their key instigators finally begin to gain the worldwide recognition their pioneering efforts deserve, we spend a special one-off weekend looking back on some of the characters, stories, sounds and inventions that shaped an era.

On day one (Saturday), we’re delighted to welcome very special guests - Radiophonic boffins, David Cain and Dick Mills - who will be presenting a history of the workshop, discussing their work, and presenting a wealth of material unheard for decades.

Gleeman Pentaphonic Synth Demo

via this auction
video below and at the auction.
"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."
