I am unable to use a vst instrument because nothing shows inside of it when i click on it. I don’t understand how do make this work.
For a start you are looking at the Media Tab which you’d use for finding stuff like Loops. You want to start in the VSTi Tab and click on the Edit Button. Or on an Instrument Track click on the Edit Instrument Button or the VSTi in the Inspector.
First: You have a filter enabled to show only audio files
Then: click on the home icon (little house symbol), click VST Instrument and drag’n’drop a chosen instrument into the project.
