How to select tracks/channels in Sound Studio 4.7.0 and later:

To select an individual track or set of tracks in Sound Studio, hold down the Command key and then click on the track(s) you'd like to select. By default, clicking once in the main waveform view automatically selects all tracks. Many users were previously unable to easily select and edit all tracks in Sound Studio, so we made this change to make this feature possible. You can read more about this feature in our user manual under Keyboard Shortcuts at http://felttip.com/ss/reference.html.
