The H8000 preset is a bit different from that example (none the strange resonances) . Plus that pitch down thing at the end doesn't happen on it. BTW I found another video by this person that has this preset and it doesn't sound as strange as the example here.
I did come up with variation that does a pitch down when you let it ring out.
This is for the XL

Thanks, Sean. You know, I listened to that other video, and it pretty much sounds just like another shimmer-rtrype effect. The example above sounds much more interesting and different. How can one reproduce those artifacts you mentioned? To me, that's what makes it unique!
