Change the sound of a track using the Track Sheet. The name of the initial program change for each track (which selects the instrument or sound in your synthesizer or sound card) is displayed in the program field. If there is a little dash in the field, there is no program change at the beginning of the track. To choose a new program for your track, click on the program field and a drop-down list box will appear. Select the new program you want. This program change will be entered at the beginning of the track.
You can choose your program names so that they correspond to the instrument(s) you have in your setup using the Patch Lists dialog.
