Thank you for the reply 
Ok that’s nice to clear up, however: It is possible to layer “samples” or “instruments” onto pads using the above method.
Perhaps some sample information is lost doing it this way? I can live with that!
Today I’ve been happily layering samples out of my Neuro Mindset and Lazer Beams libraries. This feature is one of the major perks of GA5 for me.
