1.) When you are happy with the corrections you've made to a audio track in the Master Class App you may save your settings to a preset. Go to the menu bar > "File" > "Save Preset"; label it (you can add "ps" at the end to the file name so you know it is a Master Class preset) and save it in a dedicated "MCP" (Master Class Presets) folder on your Mac's harddrive.
2.) To load a preset into the Master Class App , go to the menu bar > " File" > "Load preset" and select the preset you want. All the settings of the preset get recalled.
