I am new to Helix. I loaded a patch and saw that there are two paths? There are an amp and IR and when I follow the path it ends up with "Path A2" Then there is a line below starting with "None" instead of "Guitar" as above. And a new chain of amp and IR . It ends up with "Multi" I do not understand these paths. Why two path? And how are they connected? I do not believe that there are two amps and cab in serial ..

Can I change the setting of a preset to test different setting without destroy the patch? When I try to edit in POD HD500X EDIT the patch is edited as soon I change something. I would prefer to be able to test and if I find it nice I would like to save otherwise just leave. But the patch is edited as far I change something in the patch..
