Mac:
1. Make sure that you have downloaded and installed the Bundled Sounds Installers. You can download the Bundled Sounds installers by going to my.presonus.com and logging into your My PreSonus account. Once logged in, please click on "Products" and then "Software." On this screen, you can click on your Notion product to locate the installers for the sounds.
2. Go to Macintosh HD\Library\Application Support\Notion Music\Notion #\Sounds\Bundled and verify that all of the sounds are in this folder. The sounds should have the extension .prox. If you get to the Sounds folder and it has a red circle with a white hash-mark in it, then there is a permissions problem. You will want to ctrl-click the Sounds folder and choose "Get Info." Next, you can unlock the padlock by entering your Mac password and make sure that "Everyone" has "Read & Write" access.
3. Once you have verified that all of the sounds are in the correct folder, you can open Notion and go to Notion>Preferences>Audio and press the “Choose…” button. From here, navigate to the Sounds folder and press “Select.” This will reload all of the sounds.
