I think it is quite interesting to realize that we today still talk about gaps between changing presets on high priced guitar modelers..this is funny at least..
Well, they work differently than kemper, with different demands on the hardware; and many people don't use presets, but scenes, other categories, pla pla. I certainly prefer the kemper preset way.
I wonder if switching between presets based on captures, considering they are much more "lightweight" could be quite fast on cortex too though. Don't know if they've addressed this.
