What is the Apple MIDI Manager?
MIDI Manager is a System extension from Apple computer that was designed
to enable the Macintosh operating system to support MIDI. There are actually
three necessary components: MIDI Manager, the Apple MIDI driver, and the
PatchBay.
The PatchBay lets you “connect” MIDI software to the Mac serial
ports and other MIDI Manager-compatible programs. MIDI Manager and
PatchBay are necessary if you have more than one application sharing the MIDI
port.
If you have a Macintosh Plus or Macintosh SE, you’ll need at least 2.5 meg of memory and
System 6.0.2 or higher to use MIDI Manager.
MIDI Manager can be used with great success on Macs with 68020 or higher microprocessors (running system 6?) .
