Apple MIDI Manager: No Longer Supported

On a Performa 6x00 series with internal modem, Apple MIDI Manager does not seem to want to make the Printer port available. However, it does allow the Modem port to be selected in the QuickTime Settings control panel.
The MIDI Manager has been discontinued and is unsupported. The official MIDI interface is now Opcode's OMS (Open Music System). The latest version is 2.3.8 for Mac OS 7.5.5 through Mac OS 7.6.1 users. It is available for downloading from several sites.
