IIRC the HD500x did this quite well, you could choose to put the looper at the very start or the very end of the chain. Helix only supports one looper, but I find that it's useful to have it at the start (while I'm working on the tone) but it's best at the end when I want to use it to record a quick chord progression to solo over.
I get that now you can put it wherever you want, but action + joystick is very tedious.
Should I submit an Ideascale entry to suggest adding a button to cycle the looper's position to one of the following options:
1/ Right after input 1
2/ Right after input 2
3/ Right before output 1
4/ Right before output 2
Or is there some other way to do this that I have missed? It doesn't seem possible to have more than one looper, which would be another way to solve this - even if only one of them can be used at once.
