Requested Feature

Add the ability to import instruments from BambooTracker files (.btm). The workflow can be similar to the Import From Bank File... feature: Instrument > Import From BambooTracker File..., which opens a file dialog, and then a Select instruments dialog.

This feature will make it easier to reuse instruments across different projects.
