8-IN/8-OUT USB MIDI Interface/MIDI Patcher

Q.I've connected a MIDI device to a Macintosh via USB, and am creating a setup in Free MIDI, but the connected MIDI device is not detected (or my computer freezes).

A.

It is possible that Free MIDI and other system extensions are being read simultaneously and are causing a conflict. To avoid this, try the following measures.

Delete the Free MIDI default setting files

 1. From the [HD]-[System Folder]-[Preferences] folder, drag the following files into the trash.

     Studio Patches Prefs
     Free MIDI Preference

 2. Empty the trash, restart your Macintosh, create the setup once again, and check whether your MIDI device is detected.

Change the system extension to "OS basic"

 1. Start up [Apple menu]-[Control Panel]-[System Extension Manager].

 2. Make a note of the "Set" value in the upper right of the [System Extension Manager], and write it down for later reference.

 3. In "Set," choose "Mac OS xx basic".

 4. In the "Duplicate Set" dialog box, enter a name of "OS basic + Free MIDI," and click the "OK" button.

 5. Add a check mark to the following items in the "System Extensions" folder.

     Free MIDI System Extention
     Free MIDI Soft Synth Extention
     Free MIDI PowerPlug
     USB××Driver 

 6. Click the "Restart" button to restart your Macintosh, and create the setup once again.

Reinstall Free MIDI

 1. Drag the [HD]-"FreeMIDI Application" folder into the trash.

 2. Drag the [HD]-[System Folder]-"FreeMIDI Folder" into the trash.

 3. From the [HD]-[System Folder]-[System Extensions] folder, drag the following files into the trash.

     Free MIDI System Extention
     Free MIDI Soft Synth Extention
     Free MIDI PowerPlug
     USB××Driver 

 4. From the [HD]-[System Folder]-[Preferences] folder, drag the following files into the trash.

     Free MIDI Set up Prefs
     Free MIDI Preference

 5. Empty the trash, restart your Macintosh, and reinstall Free MIDI. Then create your setup.
