Audio MIDI Setup: MIDI Configurations Are Lost
Some non-Apple drivers may not store the previously saved configuration for all devices.
Products Affected
Mac OS X 10.0, Mac OS X 10.3
Symptom
MIDI settings you previously made are lost when you reopen Audio MIDI Setup.
Solution
Audio MIDI Setup queries the drivers for all connected audio devices in order to determine the previously saved configuration. Some non-Apple (third-party) drivers may not store the previously saved configuration for all devices. Contact the vendor of your audio device for an updated driver.
