[sdiy] Four-pole filter with vactrols (new student project video)

I hadn't noticed this while making the video, but upon watching it now, I noticed something interesting... check out around the 5:10 mark...

I switch the cutoff frequency CV signal from a triangle to a square wave - it doesn't seem to instantly snap from one tone to another, there's like a decay; you can can hear it and see it on the scope.

Is this the vactrol "ringing" effect?
