CGS Funky Dummer Module (Ken Stone)



via this auction

"One of the wildest and rarest Eurorack modules I've encountered! Strange fun awaits! CGS Funky Drummer, euro 32 hp
this is the classic clarke68 euro panel for building the cgs funky drummer module (ken stone)

more information on building the module is here:

the panel is 32hp wide

This DIY module is based on a panel designed by user Clark68 from Muffwigglers. It combines several CGS PCBs mounted horizontally behind one Panel. It consists of:
CGS13 - Gated Comparator
CGS36 - Pulse Divider and Boolean Logic
CGS31 - Digital noise

Functionally equivalent to the left half of Zthee's Serge SWAMP panel.

The digital noise is a very standard pseudo-random digital noise source with a few enhancements. Instead of running a fixed high frequency clock, a VCO is used instead, allowing for unusual sweeps, and for reducing the speed right down to a series of random pulses. The internal linear VCO can also be bypassed so an external source such as a 1V/Oct. VCO or LFO can be substituted. It has pink and white noise outputs, and two separate (unique) digital outputs for use in triggering other circuits.

The Pulse divider outputs /2,/3,/4,/5,/6,/7, and /8 with a reset button or CV reset.

The logic block consists of two inverters, as well as an AND Gate, and an OR Gate

The Gated Comparator is a bit of a doozy. It is a Comparator mixed with an 8 stage Digital Shift Register. This DSR, when clocked pusheds the current Comparator value down along the register. The contents of the DSR can be help in a loop, or Manually input. Additionally Pots bootstrapped to the stages outputs are mixed into a common out put creating a CV sequence. The so called "Klee" sequencer. Also, Also- the values of the 8 stages get converted from their Binary values at any given time and turend into an Analog CV equivalent. And that same thing but inverted. Read this to be equally confused: gatedcomparator.html
or read this post: What does my Gated Comparator/Klee do? Funky Drummer?

For more general info about this Panel:

122 mA +12V
31 mA -12V
0 mA 5V
70 mm deep
Module is available as a DIY project only"
