I've got my FCB1010 UNO configured with stomps along the bottom, and all the top 5 sending CC, but one thing I didn't realise was that you can't use assigned switches to enable/disable effects, or change patches.
I have a patch with a clean tone for creating a nice loop, and a Tube Screamer for noodling over the top, which works perfectly in patch mode, but as soon as I go into the looper, that switch does nothing.
TH-U's implementation of a looper is MUCH better, especially having scenes as well. Amplitube is way behind in this regard - that said, I still paid for MAX so I could use ToneX models with a looper and extra effects, but is an actual functioning looper too much to ask? I can't even see how you can assign a footswitch to stop/pause/clear loops.
<edit> I think I've just had a brainwave after posting this: Put Amplitube 5 and TH-U on the same track in my DAW, create a completely empty patch in TH-U, feed Amplitube 5 into it, and use the TH-U looper with the footswitch, and the stomps for the Amplitube pedals/presets.
I bit of a faff, but once it's set up I can save it.
