By range I'm assuming you mean note range. I can change the range in some of my synths but I haven't seen a way to in Studio1. But you can transpose the midi track. To transpose, select the midi track, click on edit (bottom right hand corner), click in the midi area, press Ctrl-A to select all or select the notes you want to change. At the top of the edit pane there are a bunch of options, click on 'Action' and transpose will be near the top.
