In the image above, when I hover over 'Drums and Percussion,' I find no instruments to choose from. Have I deleted any default files or folders? What is the source destination that the sampler gets the other instrument options from? I can clarify my issue if unclear. Thanks for any help in advance!
1. Go to /Library/Application Support/Logic/EXS Factory Samples/03 Drums & Percussion and check whether there are any subfolders containing .wav files.
2. If so, create a new logic project and go to your library by clicking the library icon in the upper left corner of the logic window.
3. In the lower left of the library section, click the gear symbol and select "Refresh library".
