No problem man - glad I could help you out!
As for your next question: Not sure if I understand correctly...let me see if I got it: You set up a patch, like I did in the vids, and then you want to in/decrease the delay of that patch?
Afaik, there's only one way to do that and that's setting up a new patch on a different slot with more delay / less delay on the Xpression and saving it.
Basically - as an example:
Slot 00: Channel 3, midcut, Xpression patch 20 mapped to slot 00 on your footswitch.
Slot 01: Channel 3, midcut, Xpression patch 20 (more/less customized delay on the Xpression) mapped to slot 01 on your footswitch.
Keep in mind that you can customize your patches on the Xpression. Nothing's keeping you from copying a patch and tweaking it to your liking.
