Fractured Software has released version 2.0 of its Rondo MIDI Player, adding several larger pianos as well as a MIDI library with playlists for storing, organizing, and playing MIDI files. Rondo lets users follow along with music as it plays, serving as a practice aid for professional and amateur musicians.
This is a free upgrade for existing users. The full software is US$25 and requires Mac OS X v10.3, a 700MHz G3 processor, and QuickTime 6.5.2.
