I'm using my KPA mostly in Performance Mode during my live-gigs and also in our rehearsals. For this reason I have created a few basic-rig-sounds (f.e. nice clean crunch and lead sounds) in Browser mode an have copied them in different performances-slots, because I use them in a lot of songs.
The problem in live-situations is, that when I'm optimizing a rig-sound f.e. in performance 1 slot 1 (f.e. to match my sound to the surrounding for a optimum stage sound) I cannot use the result in all the different performance-slots automatically. I have to copy it first, which -for sure- can not be managed in live situation (when using many performances).
The reason for this is, that the used rig in performance mode don't refer to the "original created Rig" in the Browser-Mode, because it is only a copy of the rig.
I think, for the KPA-live-use it would be more conveniant, that every rig in performance mode is a copy of the original rig in Browser Mode, so that a change to a rig (via Browser- or via Performance-Mode) is valid in each place where this rig is used. (I hope I'm not confusing anyone)
So it could be a really necessary feature, to be able to create rigs in browser-mode and then f.e. tag them as "global". Any change to those "global-rigs" f.e. in performance mode then cause a change of this rig also in Browser-mode so that automatically this rig-change is done in all the other referring performance-slots.
May this be a feature of the future (hopefully)
