That is one interesting case. Usually the Estradin-230 is all black.

"This is Soviet synth Estradin-230. The most successful copy of MINIMOOG (ever made in USSR).

The synth is in very good cosmetic and functional condition. It is really nice monophonic analog synth with 3 OSCs and VCF. Please see its specification here."

Note the extra patch points are both in front and back.

"ARP Odyssey Mk2
Model number 2811
Serial number 0044

As can be seen from the photos, this ARP Odyssey has been modified by the removal of the keyboard and the addition of 3.5mm jack sockets for extra CV and audio inputs and outputs. There is also a round multi pin connector fitted, but I don't know what it is for. Possibly for the removed keyboard, which I don't have. It was already modified when I got it about 8 years ago in a part exchange deal. I assume that it was done by Analogue Solutions, as there is one of their stickers on the front panel. Cosmetically, it is not brilliant with quite a few scratches and chips to the panel paintwork. It has not been serviced or any parts replaced since I have had it. When I got it a few sliders were stiff and a couple of them were crackling. So I opened it up and lubricated all sliders, switches and sockets with contact cleaner, and it has been working fine since then. As far as I can tell everything is working properly. I have played it with a midi keyboard with a midi to CV/gate convertor, and recently I checked it with a QuNexus keyboard.

Internally, it didn't look too bad, although not very clean. it looks like it might have been poorly stored as the solder joints looked dull and some metal parts are rusty.

The labelling on the fitted sockets could do with replacing as they are starting to peel off and the print is fading. Here is a list of the sockets. All socket are working. I checked them using my Eurorack setup.

Mutable Instruments Shruthi-1 Yellow Magic Edition

via this auction

"Hybrid Analog Mono Synth (Digital Waveforms/Analog Filter)
- Allows best of both worlds. Use traditional waveforms, complex waveforms and wavetable style synthesis through fully Analog Filter and VCA stage.

The Yellow Magic Edition features a moody and sometimes screaming low-pass filter inspired by the MS-20 LPF; and a low-fi digital delay. The delay has a minimal EQ section in its feedback loop, creating brooding, dark echoes or dub build-ups."

New Analog Bytes tbDSP Eurorack Module with Knob Touch Detection

"tbDSP is a modular synth that’s currently under development. It will be available in 2014. Here is a picture of the current prototype (remember, the front panel aesthetics and screen graphics aren’t finalized yet)"

"With tbDSP we set out to create not only the most powerful DSP synthesizer platform in Euro, but also a platform that could evolve over time. At the heart of this goal is the ability to add functionality and make improvements once the module has been released into the wild. To support this, we put a USB port on the module and developed PC and Mac applications so that when a new idea pops into our heads, we can share it with everyone that owns the module. Likewise, it will allow users to influence development.

Selection Knob

USB Port

Outputs (+/- 5 V, Audio or CV)

tbDSP features three chips that share the processing duties:

Altera FPGA - graphics, SD, and audio processing
Analog Devices SHARC - floating point audio processing, FFTs
Microchip PIC32 - USB, Firmware Update, and housekeeping

The FPGA processes audio at sampling rates as fast as 98MHz, and the SHARC can compute over 24,000 1024-point FFTs per second."

You can find additional details and follow progress at http://tbdsp.tumblr.com. The following are a couple of videos and audio demos.

"My appreciation of the old Atari POKEY sound chip compelled me to recreate its guts in a tbDSP engine. Some might argue that doing so is a waste of perfectly good DSP, but I saw an opportunity to make an engine with features that I wish the original chip included. The new engine is called POKE. I want to cover two of the new features here."

Chvrches: NPR Music Tiny Desk Concert

Published on May 12, 2014 NPR Music ·549 videos

Update: make that ALTO, not LTO. Only one previous post on MATRIXSYNTH. Synths include the DSI Tempest, Mopho x4, and Teenage Engineering OP-1.

Update 2 via Chris Haynes in the comments: "That ALTO is controlling a Moog Minitaur for the bass drones."

"For a brief moment, I imagined hearing Chvrches perform "Recover" or "Gun" with a couple of acoustic guitars and perhaps a shaker or two. And, though these songs would surely stand up well when broken down and bared, I'm thrilled that Chvrches came with a small arsenal of synthesizers to perform a few highlights from last year's album The Bones of What You Believe.

Seeing these now-familiar earworms executed up close was nearly as much a campfire moment as an acoustic set might have been, except the flames burned brighter. Lauren Mayberry's voice felt powerful and vulnerable, while Iain Cook and Martin Doherty kept those memorable synth lines bubbling underneath. The result works as a perfect introduction to the Glasgow trio, but also a reaffirmation of talent and longevity for those already love with the band. --BOB BOILEN

Finishing the SH-2000

Published on May 19, 2014 organfairy·422 videos

"A couple of videos ago I got the defective Roland SH-2000 back to working order - not that it was very difficult. But I still need to finish the cabinet. There is a missing top part and I make a new one in this video.

The music is something I made back in the analogue days. It is 'Little Lady' that was a hit for Scottish singer Aneka in the early 1980's. I play it on Yamaha and Technics organs as well as the other SH-2000 that I bought in 1994."

Devil Fish-Controls the Modular

Published on May 19, 2014 TB-303 Devil Fish·19 videos

"A live jam of a track called 'Sparrows HEAD' by Random Knobhead.
MIDI, AUDIO, CV signal routing-
To start in some sort of logical order, I will begin with the master tempo and transport commander:-
Yamaha RS7000 is sending MIDI (100bpm) to the Roland TB-303 Devil Fish and the Elecktron Analog four. The RS7000 has percussive parts playing from internal synth voices and is not sending out note data.
The Analog four is sending clock pulses to the Roland SH-101 and the TipTop Trigger Riot modules Ext Clock Ins, The A4 is playing a panning percussive pseudo random sound, and has the SH-101 running through its Reverb unit, it is also sending a gate pulse on the first of a 64 step pattern to the Trigger Riots Reset in.
The SH-101 is playing an internal sequence.
The Trigger Riot is sending (the A4s) Clock out to the Make Noise Woggle Bug and Echophon modules, along with Clock Divisions to the TipTop BD808 module, and Clock Division Pulses to the Echophons Freeze in, and to the Devil Fishes 2 Dynamic Bank Switching inputs alternating it between 4 or 8 internal patterns depending on if 1 or 2 patterns were selected.
The Devil Fish is sending CV to the Make Noise DPO modules second oscillator (the first is an FM source for the second which is also being FMed by the Make Noise Woggle bug modules 'smooth' random out), the Devil Fish is sending gate out to the 4MS Pingable Envelope Generator which is opening the Make Noise QMMG (DPOs channel after its filtered through the Intelligel Korgasmatron module), the Devil Fish is also sending its Accent out to the TipTop Hats808 modules Open Hat. Devil Fishes Audio out is through the Boss SD-2 distortion pedal(not used) and through the A4(with no effect).
The iPhone is not synced but still set to 100bpm it has the NodeBeat app playing a simple melody into the Echophon which has the Pitch knob modulated by the Random out of the Woggle Bug.
All Audio from the modules is routed to the QMMG then to the mixer.
The Korg Kaoss Pad 2 is a send effect for the mixer and is used to 'Stutter' the RS7000 and Modular together and separately.
I think thats all..."
