Nonlinear Circuits Poultry In Motion White and Gold Eurorack

Brand new build, never racked. Powered to confirm function. Works as it should.

Built by me, experienced builder with hundreds of successful builds.

Will ship with 10-16 power cable, 3mm screws and washers.

The upper half of the module is a fairly standard PT2399 delay with two inputs and CV control over delay time. But maybe you need a VCO that doesn't track 1V/Oct. Well, Poultry In Motion has you covered. The designer took the clock out from the PT2399 (which is in the MHz range) and divided it down to get a square wave VCO. Flip the toggle to Delay Sync for this function. The delay time controls the frequency range, fastest with the knob fully CCW (about 8.6 kHz at the /2 output), slowest with it fully CW. Then there's the Egg Timer function. I checked it with a 40,000 count DMM and found it to be pretty accurate. 63.99 Hz at the /2 output, 1.999 Hz at the /64, .999 Hz at /128 and so on. Handy for clocking. Oh, and it's 10HP.

Description from the designer:

This module is a voltage controlled PT2399 delay with sync out. It is not very practical to force the PT2399 to sync with whatever else is going on, so I took the opposite stance and decided everything else has to sync with what the PT2399 is doing.

The sync out is fed to a divider to get 12 stages of sync signal. The sync signal is the delay IC’s internal clock, which runs in the MHz range so quite a lot of dividing is done to bring it down to a range suitable for use in modular.

Anyway, the divider can be used separately, so you have a VC Delay and a clock divider on one panel. Or you can ignore the delay and use it all as a VCO with divided outputs (not 1V/oct). Or you can flick the switch and get the egg timer mode, which uses a crystal to generate a second count (0.125Hz, 0.25Hz, 0.5Hz, 1Hz, etc). This is for getting your system to work with BPM type drum machines or just to have a regular count or whatever you think might be fun.

The /8 output is fed into the switch of Delay input1 to ensure it is always spitting out some sounds and the module can run without any inputs.

The name comes from one of my favorite albums, the 1st time I tested the proto-type it sounded like an angry chicken so had to go with the theme.
