GeOsync TB-EFA / awesome 303 sauce for your VCO / VCF ENV VCA DRIVE

video upload by BRiES

"Someone lent me this module from their personal collection to explore and demonstrate. I honestly didn't expect it to sound this good. In this clip I ran a square wave sequence from the minibrute (no internal filter or vca used) straight into the input of the TB-EFA. The trigger out of the minibrute was connected to the trigger input in the TB-EFA. I added a stepped random wave to trigger the accents.

It's really really good."

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

video upload by John Schussler

"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.
