Arnold's MIDI Player 2.5.1b - A.M.P is a simple application that plays any MIDI file on the Macintosh itself or on an external synthesizer. Just drag and drop a MIDI file on its icon or its window and the song is playing ! A.M.P. needs a Mac LC + system 7 (or better) + QuickTime 2 or the Apple MIDI Manager extensions. You can use either QuickTime Music (to play to the internal speaker) or the MIDI Manager (to play on real external MIDI device).
