Not quite sure what you mean.
If you refer to input-output latency, this is only a few milliseconds, which is rarely a problem. It can be an issue if you do a parallel mix, when you can get some “comb-filtering”, but this applies to all digital equipment. KILLDRY can be helpful here.
So, I’m loading patches with external MIDI footswitches, and when I hit the footswitch, there is a long lag before the effect kicks in. Esepcially noticeable on pitchfactor algorithms. Is that a better explanation?
