Dynacord Echocord Super 65 + Microbrute

Published on Sep 23, 2015 HoldernessMedia .

"I had a nice bit of luck in finding this Dynacord Echocord Super 65 a couple of weeks ago. A little bit of tinkering/cleaning and it's running pretty smooth. The new tape loops arrived today so I had to give it a quick whirl with a little sequence from the Microbrute. I'll try to record a proper demo of this unit at some point as there aren't many audio demos out there."

Lupine Systems First Vintage DIY Analog Synthesizer For Sale

via this auction

Here's an interesting bit of DIY synthesizer history. The only other post to mention Lupine Systems went up last October here. Below are the details from the auction including a link to an audio demo. Note there is a Lupine Systems website still online.

Details via the auction:

Hello DIY synthesizer fans! Way back in the 1970's I designed a number of synthesizer systems. Many of them were basic but for the time they were quite impressive.

I used to build small devices while in school to impress my friends. I often gave away copies of the diagrams, many of which I have seen online in one form or another -- many are very simple in nature and have survived the many years. This design is a hybrid -- the keyboard is digitally scanned but the audio is generated by analog circuits. This combo allows for the use of a matrixed keyboard. The heart of the system is the M50240 Top Octave Generator chip for which the output is divided down to lower frequencies and blended to form the sound to be processed by the filters.

Up for auction is a copy of one of my original synthesizers. The original was built using pad-per-hole and point-to-point wiring. I decided a while back to draft a set of printed circuits for this design "just for the heck of it". Up for auction are the results.

The PC board had a few drafting errors which have been professionally corrected with jumpers (a corrected version is now available but not yet up for auction).

All controls are fully functional and since the photos were taken I have added knobs to all of the rotating controls. I have also added a 1/4" phone jack for the audio output mounted on the rear (not shown).

PLEASE NOTE: THE AUCTION IS FOR THE SYNTHESIZER PC BOARD SET, NOT THE KEYBOARD SHOWN. The keyboard IS HOWEVER INCLUDED. The keyboard is CHEAP and is not of high quality so it is being TOSSED IN WITH THE AUCTION to get you started. Note in the photos that one key has been replaced and does not truly match the rest but plays OK. IT IS HIGHLY RECOMMENDED YOU REPLACE THE KEYBOARD WITH A DECENT ONE rather than rely on this toss-in.

Schematics are included with this auction.

Todd Barton's Ancient Krell patch

Published on Sep 23, 2015 Stephen Drake

"So I built a 208r, version 2. It's a clone of the original version of the Buchla Music Easel, the top sound producing part. After much troubleshooting it now seems to be fully working, except for some minor calibration things which I haven't gotten around to. And I don't have a proper enclosure for it yet. While I have a 218e controller for it, it's not used in this patch, so I moved it out of the way so I could get better camera angles.

This is the Ancient Krell patch from a group of Music Easel patches that Todd Barton posted recently. It probably sounds different on this easel than on Todd's because I don't have the high range mod on my Modulation Oscillator yet, and the Timbre range on the Complex Oscillator isn't folding enough (yet). Thanks for the patch Todd!

Other than a bit of reverb from an Eventide Space (the Blackhole preset), this is a straight recording direct from the Easel to my computer."

Roland Jupiter 6 SN 291008

via this auction

"Okay, it's not a jp8, but it's pretty darn close for a fraction of the price and with some features not available on the jp8, not the least of which is that it has MIDI. If you're contemplating acquiring one of these classics you've doubtless researched the feature sets of both synths and know what a remarkable piece of analog synth history this is. Built like a tank and noted for its durability and reliability. This one is in beautiful condition. (see condition description above). The patches loaded are not the factory presets but these can be downloaded from the net if preferred. Comes with the proper 2 pronged Roland power cord."

Emu Drumulator SN 7201 with MIDI Sync

Uploaded on Oct 24, 2007 rolandsh1000's channel

"This is a demo of some of the sounds of the Emu Drumulator and how it can be controlled via MIDI."

Update: Video added above. It turns out the MIDI actually lets you trigger each sound over MIDI.

via this auction

"For sale is a EMU Drumulator. Perfect working order, and recently serviced by professional techs. Cosmetics are a 7/10. Look at picks carefully. There are some scratches, chips etc, due too age but over all a great looking and performing machine... The midi is stock, it's only sync, no trigger of voices or anything."

ERD Brings Dirt (Literal Earth Soil) to Your Modular

"Unedited recording from the ERD/ERD (Earth Return Distortion) module released 23 September from micro_research. In this recording a sine from RS-95e is passed through earth and modulated in ERD/ERD by a triangle living VCO."

Also see the ERD/SIR further below. ERD is a new modular maker.

You can swap out the dirt with other compositions!

via ERD:

"ERD/ERD (Earth Return Distortion) is the first and most extreme expression of the ERD philosophy, seeking to literally put the earth back into circuit with technology. All world electricity travels through the earth and nearly all electronic circuitry and devices are extracted and refined from the earth. ERD/ERD puts a small block of forest earth into the Eurorack circuit, allowing control and audio signals to be distorted and amplified as they pass through the earth block. It can be viewed in conventional terms as an earth conditioned VCA (amplification factor by knob control or CV) and distortion. Local electrical and atmospheric signals can condition and distort the earth signal. Two jack connections are also included, optionally switching out the local earth block in favour of routing through local earth piles and forest sites. Discounts are available in return for earth samples (eg. Edgar Allen Poe earth from Baltimore, vampire earth from Transylvania or Whitby)."

"The ERD modular eurorack series, from the creator of the Black Death and Dark Interpreter noise synth devices,aims to infect and contaminate the world of Eurorack with a radical, new artistic sensibility.

ERD/ERD (Earth Return Distortion) and ERD/SIR (Susceptible, Infected, Recovered) are the first ERD releases of 2015. All ERD modules are supplied fully hand assembled and totally Eurorack compatible (+ and -12v supplies). Each series will be sold in a limited, strictly numbered edition of 40 modules each. Future modules planned for 2015 and early 2016 include: ERD/γ, a radioactive source and true random voltage generator, and ERD/WORM speech synthesizer and vocoder."

"ERD/SIR offers a fully fledged viral computation unit including a central plague unit [CPU] acting as interpreter for selected instruction sets which operate on the interior cells or sound-generating individuals (the simulation of a medieval village within the synth). Instruction sets include masque (of the red death, courtesy of E.A Poe), brainfuck, redcode, plain plague and SIR (susceptible, infected, recovered).

ERD/SIR is a digital/analogue module which can be used as a stochastic, chaotic pattern and waveform generator. The three knob controls and CV can be used to change the speed of simulation and output voltage, the selected plague and instruction set, and to actually input instructions, live coding style, into the simulated plague processors or CPUs."
