"FreeMIDI is a complete MIDI operating system for the Macintosh. It
ships
free of
charge and is automatically installed with all Mark of the Unicorn
music
software products. FreeMIDI is rapidly being supported by more and
more third
party developers. If you are a developer who is interested in
participating in the future of MIDI development on the Macintosh, get
the
FreeMIDI
dev kit.
FreeMIDI
automatically detects what type of MIDI interface is connected to
the
Macintosh serial or USB ports, automatically detects what MIDI devices
are
connected to interface (it "knows" over 200 types of devices), and
provides a
graphical representation of their MIDI studio.
FreeMIDI
also provides pop-up sound lists for over 100 popular MIDI
synthesizers-as well as generic support for any General MIDI device. It
even
includes
advanced features such as inter-application communication, multiple
application
real-time synchronization, and support for Digidesign's Sample
Cell Nubus
card."
