I was also experimenting with it after seeing the reverb vid. There's little actual information in those vids, it's like a cooking show where they go "an now we will be grating some unicon horn on top, and sprinkle with elfen tears" I don't have a prophet 5 lying around lol.
2 things that took this patch to the next level for me: i put the filter state to about 8 o'clock and set aftertouch to filtermode down the same amount, so i can make notes more expressive and deep with AT.
I also used some tricks from these vids:
One of the masters at work, Steve Porcaro from Toto... he's so coked-up it's hilarious, but dang this cat got skills.
