There is no channel called EXS! When I open a new project, should I create a software instrument or an audio track? Do I need the track already entered at the beginning of the video before I can open it? Everyone seems to start the videos with things already set up, so I can't do anything. Please help! 😭


You can open EXS24 from the instrument slot on a software instrument track. https://app.box.com/s/hbon04phc8e27me74t8pdnhyhwfbdjij


I opened EXS24, but there is no Edit button! I think an update changed it, but I couldn't figure it out from any website. Please help!
