In performance mode your controller needs to send a CC (50-54) to select the different performance rigs, not a patch change as you might have in Browse mode.
I should also add that you can use midi program changes. You will see that bank 1 -1 is midi program 1 ( could also be program zero depending on controller). Bank 1-2 is midi program 2, etc...
So the midi numbers will/could be different than what you have in Browse mode.
In Performance mode you are recalling the performance slot and not the amp. In Browse mode you are recalling amp rig.
I do do find that there is a lot of lag in switching in performance mode with midi.
One more thing. Make sure you have an amp inserted into the slot you are trying to recall.
