Choose a patch
You can view available patches for the selected track in the Library. When you create a new track, you can choose a patch from the Library, and choose a different patch for the selected track at any time.
A track can have only one patch for the length of a project, and you can only choose patches that match the track type of the selected track.
Choose a patch for the selected track
Click the Library button in the control bar (or double-click a track header) to open the Library.
Choose a patch category from the list on the left, then choose a patch from the list on the right.
You can quickly move through items in either list using the Up Arrow and Down Arrow keys, and move between lists using the Left Arrow and Right Arrow keys.
