Hello, I have some Advanced Orchestra samples that I tried to load into EXS. During the loadup I got a dialogue box asking which of multiple files I meant to be loading (the names of the aifs are just a1.aif, a2.aif, etc. generically). And I clicked the wrong set of files so now my string runs are playing trombone crescendos. How do I go back into the EXS instrument and reconnect the correct files? Thank you!
