Hello For some reason when I click on instruments in the Channel Strip Settings I get this message: EXS Instrument "Example.exs": Audio file "example audio file with a long name.aif" not found! Running a spotlight search reveals that these files do not exist on the computer. It's highly likely that I have screwed things up as follows: I previously had GarageBand V1-4 and Logic content moved to an external drive (including instruments) which worked fine but was awkward. I then decided to have the Logic content back on the internal disk so have installed it (the content only) from the DVDs, and have installed GarageBand 5 (iLife 09) but not all the earlier versions. Perhaps these missing instruments belong to GB V1-4, in which case why does this message affect so many of them? Is there a way for Logic to reindex its instruments/instrument samples (Like it can with the loops)? There is no problem with missing loops. Or should I reinstall Logic - in which case should I uninstall first, and if so what is the best way? And should I reinstall GarageBand V1-4 (if I still have the disks)? Is there a definitive guide as to which program provides which content, and how to make it available to both GB and Logic? Sorry - that's a lot of versions of the same question!
