So this is another Eurorack patch using external devices: here, my homemade cracklebox.

I built this thing quite a while ago; it's a copy of the classic STEIM Krakadoos design. Its oscillator exploits bugs in the design of the ancient μA709 op amp chip to produce squelchy and crackling sounds when you touch the brass buttons on the left hand side. I've been intending to supplement the audio output jack on it, which is directly wired into the discrete amplifier circuit, with an output transformer; I've been told that doing that will make it so that plugging it into something doesn't couple that amplifier to the internals and change the sound.

But I decided tonight that before making any modifications, I should try plugging it into the sync input of my VCO 3340. This audio clip is the result: a solid chip oscillator being intimately tied to a weirdo.

The original zwoopy bounce is the patch as it stands without sync added, and then I turn the Cracklebox on, soft-syncing the VCO first with the ultrasonic base waveform of the Cracklebox, and then going through varying pressure on different patterns of touch knobs. I flip the Cracklebox off in the middle and switch to hard sync before going through the process again.
