Eurorack acid - TB 303 style modules

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, 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.... 00:00 Intro 00:20 Hydronium 07:28 TB-EFA 13:56 Acid Source 24:14 Pico Acid 30:00 Doepfer A-103/120 46:16 Vult Freak
