Patch volume slider not showing in ToneLib...

Every image of the ToneLib interface that I've seen shows a patch volume slider at the top right of the interface. It's not showing on my copy of the software. What am I missing? How can I get it to appear? I'm using ToneLib 4.3.1 free, with a Zoom MS-70CDR pedal. Thanks for any help.

UPDATE: I've just read in the manual that the volume control is not available with the pedal I'm using. Sorry for the oversight.
