Re: Is there a "copy preset" (and paste) function in the Ultra?
I don't use the looper much, but I do have one patch where I use it in a way that slightly differs from what you're doing. I'll describe it here, even though it doesn't specifically answer your question, because it might give you a different approach that might also be suitable for your use.
I use a single patch, not two (hence the "not answering your question" glitch). But it's a dual-signal chain patch. On one signal chain, I have a clean amp, chorus, the looper, and also a drive pedal in front for a little occasional grit. On the other signal chain, I have a lead tone (amp, delay, and an optional flanger). The two signal paths meet just in front of the reverb, and then out to the output. The main thing that makes this usable for me is I assigned an expression pedal to morph between the two signal chains (* see note). At heel-down, I get the clean sound, record my loop, stop recording, let it play by itself, then push the pedal, and at toe-down, I get to play lead on top. At any time, I can heel-down again, and record additional layers onto the loop.
It's actually a pretty bad patch - tuned way back in f/w v5.x. Since then, both the Axe f/w itself and my soundscaping capabilities have evolved a lot. So I find the patch sound like crap. However, it's really cool for capturing quick rhythm parts and then jammin leads on top. I use it a lot for practicing (where I can forgive the poor sounds), and it actually inspires quite a bit to use a looper that way.
Anyhow, consider doing it with a single patch, as described. Nevertheless, I am also interested in finding the answer to your real question, which is how to enable the looper so that spillover in two patches (with the looper, of course) works as required.
(* Note: unlike the "usual" setup for morphing between two signal chains, in this case I'm not fading the levels of the two amps in opposite directions. Instead, I assign the controller to (a) the looper's ingain parameter in a negative curve and (b) to the lead amp's output level in a positive curve.)
Hope this can be of some help. The Axe is filled with infinite potential, so sharing these thoughts can always be useful to someone.
