Roland TB-303 with Acidlab Mod – MGD Wishlist

Posted on 19 March 2013 by MasterDelight


Perhaps one of the most coveted TB-303 mods in the history of the synth. Almost impossible to find on eBay (units have been sold for over a grand) and, to make matters more confusing, there is another Acidlab synth company that has a similar product but is not the same. Also, this picture: Venetian Snares¬†using one of these mods (although he’s got colored knobs ’cause he’s cooler than most of us). So, all that adds up to an MGD wishlist item.

Here are some details about the mod found at Matrixsynth (with more information at Synthfind):

Mod details:

  • The inputs are q- accent- gate- slide- vcf- vcf cut off-vca-cv these are for use with a midi-cv converter, analog synth or tb-303.
  • The outputs are eg- accent- slide- square- saw- vcf these could be patched to an external filter or effects unit or tb-303.

Toggle switches:

  • Accent – up normal, down accents on all notes
  • Slide – up normal, down slide on all notes
  • Waveform modulation – saw, square
  • Resonance – up normal, down rear vcf input.


  • Decay – from off to standerd
  • Resonance – adds q level
  • X-mod – modulation level
  • Overdrive – volume control of vco to filter
  • Pots come with 303 type knobs to retain original look.
  • LEDs: three new LED show programming accent, slide, bend.

Motherbrain’s Custom Console

Posted on 05 March 2013 by diode

Motherbrain, a recording studio in Brooklyn has just been outfitted with one of the most gorgeous consoles on earth. To be exact, it’s actually (now) an analog console / DAW control center. UM Project did an absolutely amazing job retrofitting and modernizing this late 60′s¬†Wiener Schwachstromwerke board. It’s been lovingly appointed in a custom bent ply and steel chassis. From the small pictures on their site, it is a little bit difficult to see exactly what is going on but it looks as if on the left there are 14 channels of original analog input, 4 aux returns or busses and a master fader. The center section has been fitted with an Avid/Euphonix protools control surface and what looks to be some tonelux 500 series outboard. The whole right section of the board is set aside for two rows of full size 19″ outboard mounted horizontally and containing an LA-2A, Retro Audio and more.

This desk is just stunning. I’m sure gearheads will make the trek to motherbrain just to feast their eyes on this piece of art.

Analog – a new animated film

Posted on 26 July 2009 by diode

Very very very very very well done animation featuring characters who are part synthesizer. Looks like it was done by a Brazilian team which is interesting since my wife and I know several excellent Brazilian artists in the VFX industry. Check it out … awesome sound design as well.

Custom Line6 Echo Park

Posted on 18 March 2009 by diode

Line6 Echo Park delay pedal in a custom enclosure. The pedal has been modified to include “true bypass” and a carling tap tempo footswitch. The power supply was also modified to accept either 9VAC or 9VDC …and it also has BIG KNOBS!

I’ve been using it this way for a few years with no labeling (I finally memorized the controls after a while) and no switch for the analog and tape emulation modes. It has been permanently set to “digital” for a long time.

The picture below shows an added toggle for delay mode select (analog/digital/tape). Finished this yesterday.

After I added the toggle, I decided to finish the job and label everything. Done!
