Ahh, the joy of infinitely evolving, uhmmmm, textures?
Probably not worth breaking down because this thing probably makes sense or it doesn't...
Initially inspired by the Karplus-Strong thread, I felt bad grunging up nitro's thread as this is getting pretty off topic, although related.
So, the WG is getting note info from the arpeggiator (and/or NoteCV) and it's amplitude is controlled by the DADSR envelope. The output feeds a mixer which then goes thru a low pass filter and a delay. The delay feeds back to the mixer creating a loop. The filter in the loop helps keep the loop from self -oscillating out of control. To change the delay depth (wet level) and close the loop use the marked Delay Out (or 'In', depending on how you like the echo tail dealt with) as opposed to the mixer In2 which is much harder to adjust without bursting into insanity.
The Sub Osc and state variable filter create the UltraLFO (do a search of the site) which changes the Pitch over time. The Sub Oct Octave and Semi knobs control The LFO speed. The top oscilloscope shows the speed of the LFO output altering the pitch.
Generates bowed, plucked and bell liked textures, try adjusting the Sustain level as well. Don't forget the Arpeggiator has an off switch. Switch to pattern mode to adjust manually.
You can drive it into blissful feedback and self-oscillation by CAREFULLY raising the upper right Res knob, usually somewhere around 9 o'clock.
It seems like the delay loop (and maybe filter roll-off?) causes a form of additive synthesis, you can see the saw wave is modulating with sine waves.
And... tweaking the arp rate is cool. An obvious application is to raise the rate as the pitch rises and vice versa. Wish I had some kind of Midi control surface, this kind of thing would be fun to 'play' live.
