What I was saying is that you can separate audio interface caused latency from plugin caused latency by temporarily removing your plugins from the guitar track, and then seeing if you have a delay from just the raw guitar signal going to the track.
Audio interface latency would show up there if you had any. An absence of latency with just your raw guitar signal to the track would point to one or more of the plugins causing the problems.
By adding back plugins one at a time, you can eventually figure out which one(s) cause the latency problems.
If on the other hand you heard latency with no pluging - the raw guitar signal, then you have to figure out a set of ASIO settings that will lower your latency.
ONE of the above two should - I think - be relatively easy to work through, and would seem to be reasonably of isolating the cause.
