I was fiddling with the polivoks vcf's resonance this evening and came about a startling setting. Something I can only describe as a sustaining vinyl needle slip.
The only modules in this set up (as shown to the right) are a Livewire Dual Cyclotron -> PlanB Model-15. the Model-15 pulse out -> Polivoks vcf -> Model-13 set fully open (vca-only setting).
The polivoks settings are static, no modulation inserted into the unit of any kind. The input attenuation is at about 60%. Luckily (or not, depending on your opinion) I'd been recording the patch. I brought the cutoff down slowly, once the "needle scratch" is sustained I touched nothing else. The circuit eventually stopped and restarted the oscillation on its own.
It doesn't sound pretty, thats for sure. but we likes it.
