"These units were produced for educational purposes but as you can see they are easily integrated in to a banana cable modular synth set up (eg Buchla, Serge, Modcan A, Phenol, Fenix, Bugbrand, Lorre Mill, Ciat Lombard etc)

It's a collection of various logic, digital and simple AD/DA circuits with a few analog sections and a HEX input key pad.

I've seen them advertised as "Analog Computers" which of course they are not, but I can see why some folk might think so.

I intended to use this with my Serge system but never got around to it and now I need the space.

The high/low switch for the digital clock speed needs replacing."

"One works perfect and is in wonderful cosmetic shape. The other one powers up, plays the rhythm section but the keyboard doesn’t work. So one works perfect and the other is for parts. The parts one is missing the battery cover."

TAMA Techstar TS204 Analog Drum Synthesizer w/ Hand Clap SN 201075

"This is a cool rack unit that can be triggered via pad or a trigger pulse from something like the Arturia Beatstep Pro or Behringer RD-8 drum machine. I have used both to trigger it as well as Simmons pads. The hand clap can't be tweaked much, but it's nice and clappy. The Synth on the other hand is bonkers. It has a longer release than any other Techstar drum sound. I have one of the bigger 6 channel Techstar units as well and this one is the longest. It has an LFO which no other Techstar sound has either."

DivKid Ochd w/ Manis Iteritas | LFO Chaos

Published on Dec 29, 2019 Nostalgic Ruckus

"Been waiting for something like this for the skiff. Luv my clock dividers and multipliers and this kinda does it with LFOs. Cranking that rate knob is a beautiful thing. The Manis with all the patch cables is being modulated by Ochd only. The other Manis output is plugged into the E440 filter to tame some unwanted harmonics but also add some resonance when Ochd gapes the envelope. Attenuating Ochd's outputs with Bored Brain Splix. The CV input on this thing is crazy cool when self patching it just didn’t do it on this patch."

POLYGOGO Stereo Oscillator - Sound Demo #2 - Eurorack Modular Synthesizer

Published on Dec 29, 2019 MIKE LEE BIRDS

"In the previous video I used the amazing POLYGOGO as sort of a drone/soundscape machine.

Here it‘s hooked up to the beautiful TUESDAY procedural sequencer from „This Is Not Rocket Science“.
The fold circuit serves as a VCA and is fed an envelope from MATHS. That same envelope goes into the OP (internal FM) Amount input for a quasi-sort-of-filter idea.

About the fold-VCA thing:
I noticed that feeding a negative voltage into the fold circuit and turning the attenuator to between 2 and 3 o‘clock will silence Polygogo. A positive voltage can then control the volume, hence Maths.
More clearly: Maths channel two is sending negative voltage (knob at 9 o’clock) through the sum output and channel one adds an envelope triggered by Tuesday.

- CHANCE changes polygons.
- MONSOON (Clouds) is responsible for reverb and adds pitch shifted delay later on.
- BEAST’S CHALKBOARD does some octave shifting off screen.
- PEAKS provides bass drum and hihats triggered by Tuesday’s beat and ticks outputs respectively. Sorry for the clipping bass drum.."

ARP ODYSSEY 70s Mk1 White Refurbished & Future-Proofed

"Fully Refurbished & Future-Proofed, sparing no expense. This process took a whopping 23 hours of skilled labor. Part of this time was spent attempting to rebuild some of the original potentiometers, but they didn't meet our high standards after our efforts (they usually don't), so we decided to replace them all with new ones. In addition to a full servicing, we took preventative measures so this Ody will hopefully outlast all others out there. The work we did included the following:

Full disassembly and deep cleaning inside and out.
Power supply rebuild.
Recalibration.
Replacement of all tantalum capacitors.
Removal and replacement of all rubber key bushings.
Cleaning of all key contacts.
Cleaning of bus bars.
Adjustment of keys.
Replacement of all potentiometers (approximate parts cost $300)
Cleaning of all switch contacts.
Replacement of power cord.

Post-restoration, this unit works like new again and is a real pleasure to play. Sure to make its next owner really happy. This unit is much better than the rest and is priced to reflect the investment we made to make it better than others on the market.
