I can't even drag and drop into a performance any more. I can drag and drop the first one in slot 1. But dragging does not work in any other slot, well at least until I discovered that you have to turn the slot on and the profile is then displayed.
Also the component controls do not seem to work in performance mode when using the remote to change . For instance I cannot adjust the Amplifier settings for the selected performance. If I change to a different performance profile the compressor is on in the performance but showing off in Rig Manager. If I turn it on and off it then shows the current status. If you adjust the parameters on the Kemper they are not reflected in RM3. It is all slightly random.
Is it right that the space bar is used to toggle the components on and off?
