Analogue Renaissance ACID SCREAMER TS-303-GT: Morphing Distortion 2nd Prototype

The Acid Screamer morphing distortion eurorack module by Analog Renaissance utilizes the Sound Semiconductor SSI2164 QUAD VCA (see this post for some notes form Analog Renaissance on the SSI2164).

Details via Analog Renaissance who will be at SUPERBOOTH, booth H254:

"The shape by which the waveforms are bent, can go seamless from distortion (hard clipping like the DS-1) to overdrive (soft bend the waveform outward like the TS-808) and also in the opposite direction to what I call underdrive (bend the waveform inward) and looks a bit like wave folding + anything in between.

The shape can be seamlessly adjusted from perfect symmetric (like the OD-1) to assymetric (like TS-808) and beyond to one side of the waveform being overdrive and the other distortion.

This bending is frequency adjustable: You can select the part of the audio spectrum that is bent and the selectivity. This is somewhat related to a filter, but in this case it only affects the bent part of the signal and has interesting effects like isolating out the sequencer noise of a 303 or turning it into a bassdrum. This frequency selectivity is constructed around a SSI2164.

Like the previous MK2 version this one is remains capable of restoring the signal dynamics associated with overdrive and distortion effects.

Contrary to the previous version, the whole design is done from the ground up with voltage control taken in mind and a full modular version is in the works with CV-control for all parameters.

Do drop by if you're interested in more about these things. I'm at booth H254"
