Let's Splosh!
This is 8 different rectifiers processing 4 input signals. It is happy to work with audio or CV or both at the same time. It has 16 outputs that will deliver 16 different signals made up of components of the 4 incoming signals. To put it simply, it makes a gloopy mess of the incoming signals and smears it all over your patch. If this module name and the food names make no sense look up some sploshing videos on youtube. That is pretty much what this module will do to your CV and audio signals with corresponding amounts of pleasure for the receiver.

This uses the core circuit of the Korg 3100 Resonator, with component choices for the filter sections as per the mods introduced by RJB in his blog back in 2005.
The main difference of this version is that it has 4 VC bandpass stages and a feedback control, the original has 3 stages and no feedback. The 4 VC bandpass stages can be controlled by a single CV on input 1 (with an attenuator) or individually with each of the 4 CV inputs.
The CV processing sub-circuits are greatly simplified from the original Korg version, simply using op amps to drive the vactrols.
The 2 inputs are summed together. Out 2 is an inverted version of Out 1.

Timbre & Timbre
This is simply a dual version of the Timbre!, which was based on the Buchla circuit. It is all smd (the single version is thru-hole) and the tri2sin circuit has been dropped, there is an input attenuator for each section.

The only changes to the original version are to fit the
signal levels to Eurorack standard. The circuit will deliver some noise when
there is no input signal so it is best to patch it directly to a VCO or patch a
VCA downstream. The original Buchla Timbre was the waveshaping section of a VCO
so there was always an input signal.
