Re: Who here uses MIDI, Programmable looper or any bank/patch system live?
Right and this is how those racks got so big. Running some effects in parallel (because of the audio gap) and some in series, a line mixer, etc..it adds up $$ and weight. Even modern multi-effects are better at switching, but not 100% seamless. They may have delay trails go over, or reverb spill over, but it takes time for the memory to be flushed and a new sound loaded in. On my Fractal, it is about 50-100 ms, which is noticeable. So you have to do creative programming to hide that.
Lexicon doesn't make a decent guitar-oriented processor; they're designed for PA or studio work. I'd know because I tried to use both an MPX-550 and MX-200 in a guitar rack. The 550 sounded pretty good and switched quickly, but was quite limited as far as processing power and simultaneous effects. The MX200 would run two effects at most, switched very slowly, and it muted during switching. That means that your guitar rig would be 100% silent during a patch change unless you had a line mixer or parallel loop for effects. Rackmount multi-effects also don't include any boost functionality; you'd need a loop switcher and a few pedals for that.
