Posted in Announcement on October 9th, 2009 by admin

This listing is out of date, please check this one for the latest information: http://macumbista.net/?p=1416

It’s a bit painful doing this, but I have some urgent bills to pay in the next 4 weeks. I’m selling my mixed Cwejman/Analog Systems/Doepfer A-100 modular synthesizer system as well as one Sennheiser MKH40 microphone. Selling the synth isn’t as bad as it seems, since I’m currently more than halfway finished building the DIY modular of my dreams…

Click photos to enlarge, of course.

This A-100 system of mixed modules from Cwejman, Analog Systems and Doepfer is about two and a half years old, is in very good condition and is located in Berlin, Germany.

I’d prefer to sell the whole system together, but I can sell individual
modules if needed. Base price is now 75% of retail.

Doepfer A-100 Suitcase 220V    EUR 370 /75% = EUR 277.50

Halfway across the Great Loneliness…

Posted in Documentation on October 7th, 2009 by admin

The only true wisdom lives far from mankind, out in the great loneliness, and it can be reached only through suffering. Privation and suffering alone can open the mind of a man to all that is hidden to others.

—Inuit shaman Najagneq, recorded by Knut Rasmussen

If you want to build a modular, my advice is not to do it if you want to have any friends, it takes too much time.

—Jessica Rylan


(click photos to make them BIGGER)

My new DIY synthesizer project is getting better and better. Right after I got my residence permit I realized I had almost a month in Berlin without having to get on a plane, train, bus or boat, so I decided to maximize that time by going deep into the modular cave. The Great Loneliness indeed–but with incredible revelations! This is the realization of a dream I’ve had for ten years now, so forgive me if I geek out for a moment…

The modules I’ve built, from top left to right:

TOP ROW
Two Dual Thomas Henry XR-2206 Voltage Controlled Oscillators (Bugbrand PCB layouts, self-etched)
4×4 Bipolar DC Matrix Mixer (Ken Stone CGS 33 & CGS 04 PCBs)
Blank Panel (singlewide)

MIDDLE ROW
Super-Psycho Modulation Source (Ken Stone CGS 21)
Wave Multiplier (Ken Stone CGS 29)
Blank panel for another Dual Thomas Henry XR-2206 VCO (will complete tonight!)
Blank panel (doublewide)
Two channel DC Mixer (three inputs per channel, large jack outputs)(more CGS 04 PCBs)

BOTTOM ROW
Dual Synthacon Voltage Controlled Filters (Marc Bareille PCBs)
Dual Polyvoks Voltage Controlled Filters (Marc Bareille PCBs)
Blank Panel (doublewide)
Blank Panel (singlewide)
Breadboard Prototyping area (= doublewide blank panel)

Besides most of the PCBs, I’m really committed to making every part of this thing with my own hands. Some people in the synth DIY scene send their front panels out to get professionally etched and anodized. I’m not really concerned with having the “professional look”, partly for financial reasons, and partly because it’s really important to be able to rapidly prototype things, get them in the case and make some fucking noise. The fact that it looks handmade separates it from all that store bought crap that people don’t have any clue what goes on inside of anyways.

With that in mind, I found a great “finish” for the metal by using an orbital hand-sander and 100-grit paper. Very Neanderthal, just the way I like it! The top row modules all have this finish. I’ve got some metal-stamps on order for the panel lettering, and then I’ll probably clear-coat each panel to keep the finger-grease out.

Speaking of noise, sounds soon, maybe on the weekend.
