There will be some latency while switching between the slots of a performance if the Profiler is connected to Rig Manager at the same time.
This is explained in the reference manual.
Ahhhh ok thank you. I haven’t really noticed what’s happening live. I don’t do many quick preset changes. It’s usually one preset per song. I use the morph feature for a volume/gain/mid bump instead of an entirely different preset. I gigged last night though and didn’t notice any lag on one particular song that I switched presets.
