I have had my G5 for pretty much the whole time its been out and love it. Lately I have been getting into more of the ambient - guitar swells, reverby washy type of stuff (maybe to loop while playing another patch on top of it live etc) and I have also noticed that sometimes when switching patches from one of those patches, I will get no sound from other patches - I can switch through a bunch of patches with no luck, but then ultimately, the other patch will come back. Since I play live, I am concerned about this happening on stage. I am not so sure that is a problem with my unit itself, but more of a design flaw, maybe tied to using such a processor hungry patch. Anyone else ever have a problem with no sound when switching to ap atch, with no way to get sound for awhile?
