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.

Bindubba Sequencer - Eurorack version

This is a re-boot of the bindubba3 sequencer which was originally released in March 2010, tho there have been a few changes since that version. The bindubba3 has no software or microprocessors on board, it is all CMOS, op amps and vactrols.
It is designed to be used with the Divide & Conquer.

This sequencer has 6 inputs to control the stepping. Two clock inputs control the count in horizontal and vertical directions. The two jump inputs send the next step somewhere else that depends on the 2^2 and 2^3 counts of the chips of both step directions......ie somewhat uncontrollable but it enables more complex patterns to be created. The two direction inputs change the direction of the count.

There are two voltage controlled slewed outputs, two CV outputs giving the same CV, 1 inverted CV output and 16 gate outputs.

Covfefe buss board

This buss is designed for use with the small PSU board.
It has 10 connectors, space for decoupling caps, LEDs, 8 mounting holes and spade mounts. It has connections at both ends so that it can be daisy chained. The PCB is 2mm thick to reduce flex when plugging/unplugging.
