I have this feeling like I should be hearing the drum from the library "in place" when it has that orange dot next to it.
the normal preview icon (headphones) is greyed out when I am in hotswap mode - this would seem to indicate that I shouldbe getting a preview of the drum from the library in place of the one in impulse I am intending to swap.
Otherwise how are we meant to find out if it is a good swap?
