This plug-in provides a quick reference guide to the ranges of the instruments present in a score. The user can choose to either see the ranges for all the instruments in the score or to simply select a staff or staves and see just the ranges for the selected instruments.
The plug-in also recognizes any instrument changes which may occur on that staff and includes them in the reference. A built-in translator outputs pitch names and octave numbers as opposed to midi numbers. In the standard plugin, the text is outputted to the trace window for a program inclusive quick reference. For the Pro Version all information is contained within the dialog, so you can check many things before closing the window.
