PX Mini Editor - No MIDI on MacBook Pro

[Nevada Princess]

All,

I have a Pandora PX Mini guitar effects processor that has the ability to interface with a computer through a MIDI driver. I have installed the driver, but when launching the software there is no option to select a MIDI driver...it's simply blank. I can't seem to find any other support references, so perhaps someone here knows where I might turn?

Thanks very much!
