I'm sending different midi controllers from Cubasis 3 on my iPad to the Kemper, as documented in the manual: CC #47 to preload a performance and CC's #50-54 to load the slot. I find out that the Kemper is very very slow (I'm talking about 2 seconds!) in responding to this midi data. I monitored the outgoing midi signal from Cubasis, and it sends it well on time to the Kemper. It's the Kemper that takes this long to switch slots. Anyone?
