studio - selfmade and modded gear

in research for the perfect sound i built a lot of synths and other stuff.

i plan to make subpages for the individual ones.

ML 303 - the most accurate TB303-clone

First: it was NOT me who created this jewel. This goes far beyond my capabilities. I put it in the selfmadesection because it fits much better to the other DIY-projects.

This is a new repair-modding-project in 2008. The ML303 is a private noncommercial DIY-soldering communityproject from germany and is widely considered as the most accurate TB303-Cone - this might come from the fact, that it just IS a TB303 - exactly the same circuit, same electronic parts from japan, VERY accurate details like the 5.333V in PSU and much more ...

I grabbed this from the bay. Not cheap although it was announced as nonfunctional - which indeed was true :) Read more about my attempt, leading this piece of electronic bay-junk to a whining, yelling, pumping, babbeling musical instument with some capabilities, a lame original TB303 can only dream of.

Syncussion Zapp

It is a drum synthesizer. You feed a trigger-signal into it and get a short sound out of it. There are 4 simple decay-envelopes, 2 VCA, a double-oscillator with frequency- and ringmodulation, a versatile noise source, a typical twin-t-circuit drumvoice, an attenuator and a multimode vcf.

MoogOSCar - a 20year old prototype

Not realy selfmade. I bought this unique prototype of an OSCar (sitting in a case of a moog source) in a horrible condition and brought it back to life and music. see some pix of the long way from a piece of junk to a jewel

stereo optical compressor

a very simple stereo compressor using a ldr-led-combination. it is definately NOT the ultimate mastering-weapon for the perfect mix. but it was fun to build it.

amputator - tubefilter/distortion

this should have been something like the spl charisma which i didnt like because it was to neat (no real distortion)

this one has a 2-band tone control, in- and out-levelcontrol and only contains some resistors and condensators and 2 tubes, no silicon
