Mosaic 1.5's new instrument library helps you easily create any ensemble you wish when you are making a new Mosaic document or importing a standard MIDI file. Instrument definitions instantly generate voices, staves and views with the proper clef and transposition (for score and part), note range, staff name and staff abbreviation. Definitions can be easily modified, and you can create as many custom instrument definitions as you like. You can even order them as you wish - alphabetically or score order.
