Eurorack acid - TB 303 style modules

video upload by John Schussler

"If you listen to techno, you listen to the Roland TB-303. It's the sound of acid, and is such a unique sound that everybody wants and uses it.

Although several makers are selling clones in the original 303 design (with the sequencer and original layout), you may just want to get one in Eurorack without all the fuss of learning the 303 sequencer interface (it's not intuitive).

Here are a bunch of 303 modules that either include all the parts (VCF, VCA, envelope, accent, glide...the works) or just one part (the VCF, which is the most critical bit).

There are others as well, these are just the ones I happen to have...."

TB-303 redux: GeoSync TB Super-O vs. Acid Rain Chainsaw

video upload by John Schussler

Update: video re-uploaded.

"I got ahold of a couple modules from GeoSync recently, the TB Super-O triple VCO and the TB-EFA filter/VCA. I also have an Acid Rain Chainsaw, and it occurred to me to wonder how the Chainsaw would do as a 303 source for the TB-EFA. How different might they be?

Of course they're different, but y'know, how exactly?

As with so many of my videos, this is just me trying to answer a random question of comparison between two modules.

Sequence from Stochastic IG. Envelope from Zadar.
