What was you did not like about using performances if you feel like sharing?

Of course:
I use the Kemper exactly the same way I used all other amps: I used many amps, the best and "longest-staying" IMo was the Elmwood M60 Modena amp, a 2x2 channel amp with the fucking coolest sounds (flexible, warm, with power and growl even on lower volume settings)...
4 channels (of course "rigs") with different effects - controlled by the GCP
But I don´t need to build any performances (by songs or by any proceed)...
I play in a few bands, a wedding combo with lots of Top40 songs, oldies, rock, pop with acoustic and electric guitars,
an acoustic band without any drummer focussed on good singing and cool music,
an acoustic duo with some funny lyrical songs,
stuff with just a female singer in bars, etc...
and I am a "sub", I don´t know, if that´s the regular name: so if a guitarrist is ill, the band calls me to help them out... (sorry for my bad english - I hope you understand everything)
So I like the idea of having my rigs (the amps channels) clean, crunch, lead, heavy (of course with the Kemper these are different amps!) to switch between them on different banks.
So i use two different banks with 4 "channels" each an different effects
plus a bank for acoustic guitar sounds
and a bank for special sounds (like U2stuff or special delay settings for Pink Floyd or something like that)
with the browser mode it´s exactly the same as i am used to with amps,
i can use it with every kind of band i am playing the concert,
i see the amps name on the kemper and the GCP, I can switch on and off all stomps and effects...
I tried to get there with performance mode one day, but I didn´t like it...
Best regards guys!
