"This is a one of a kind build of the well known TR-909 voice boards and controls and outputs clone, information is available online for the 9090 projects.
This unit was built in Russia and has no problems or issues, I’m regretfully selling and will miss it.

Beautiful metal case, 10”x10”x 4” tall (plus knob height).
Individual audio outputs allow much better control and mixing over every drum tone.
Hear this unit on many of my YouTube videos as RhythmDial techno.
Features MIDI in and thru, plus DINSync out as well.

Euro 240v internal power, also includes a wall-plug-end converter to use in US 120v.

Light weight and well built, this machine is a brilliant way to get 909 drums with some extra tricks in the mix."

"ALL three oscillators worked and boy did they sound HUGE!
The Filter section works great and sounds bigger than my Moog Voyager XL!
The MIDI / CV works, I used my AKAI MAX controller to test CV and MIDI.
The Multiples card works.
The LFO works.
Sample and Hold works.
BOTH Envelope Generators work.
The 4 Channel Mixer works.
The Instrument Interface Amplifier works.

And…
The Amplifier Response card works but when I patched it in, volume was a bit low and a little distorted. Now, I am not sure if I did patch it properly or if there is an issue with that card. That said if there is an issue, a new replacement is under $100 on the Syntheizers Dot Com site. Also the Reverb passed audio but i could not tell if the sound was correct... again, might be due to my lack of knowledge / understanding on modulars, might be an issue."

Cyndustries Zeroscillator VCO MU analog synthesizer module

"RARE used Cyndustries Zeroscillator module in MU (Moog/synthesizers.com) format. The module works perfectly was purchased by me several years ago and has been well kept in my smoke free home studio. Some minor mounting ware on the panel but nothing serious. This is the rev 2 version of which i believe 20+ units were made. You see it has the stacked pcb boards found on the early versions of this module. This has been the centerpiece of my system for many years and it kills me to sell this rare and wonderful module. Selling off the rest of my system, as I no longer have the time."

Roland System-8 Jupiter-8 Patch Demos by GEOSynths

Published on Jul 7, 2018 GEOSynths

Playlist:
1. Systematic Vol 1 - Patches 1 to 32 - Jupiter 8 Engine

Here's the first video of two, highlighting the patches i've made with the JP8 Engine. I've gone for the types of sounds I like to make, as opposed to lots of old, well known Patches, as there's a number of these available. I think the JP8 Engine is really good, lots of tonal variation.

2. Systematic Vol 1 - Patches 33 to 64 - Jupiter 8 Engine

The final 32 Patches I've made with the Jupiter 8 Engine. It's a very flexible Synth engine and can do some great Sounds.

Roland System-8 FM Patch Demos by GEOSynths

Published on Jul 4, 2018 GEOSynths

"So, just as I was doing my Set for the System 8, Roland brought out an update V1.20 that adds a load of new Features, such as Filters and FM Capabilities. I decided to make a new Bank that utilizes the new features and specifically uses the FM Oscillators...There might be 1 or 2 that have some more traditional waves, but there is at least 1 FM Oscillator being used...It's a great addition to an already great Synth."
