Installation Instructions

Do not connect your USB MIDI interface or controller to the computer yet!  The driver installer should be run first!

1. Download the latest M-Audio driver for Mac OS X from our drivers/updates page.

2. The file you are downloading is in "Disk Image" (extension "dmg") format.  This means that once the download is complete, your Mac should automatically launch the file and create a virtual drive on your desktop - you will now see two new icons on the Desktop.


Note: The current MIDI driver version numbers will not match the pictures in this guide, but the process is still the same


Immediately after this, a finder window will automatically open and show you the two icons below:


(If this Window did not open automatically, double-click on the downloaded Disk Image file).


3. If this is the first time you install an M-Audio USB MIDI driver on your system, please skip to step 7 of this guide now.  If an M-Audio USB MIDI driver was previously installed on your system, it has to be removed before you can successfully install the new driver.  Please double-click "M-Audio USB MIDI Uninstaller" and follow the instructions on screen.

4. When prompted, enter your administrator name and password to continue with the driver removal.

5. Restart your computer to complete the driver removal.

6. After your computer is fully restarted, double-click on the downloaded Disk Image (dmg) file.  This will bring you back to the contents of the virtual drive and show you the same two icons (M-Audio USB MIDI Support.pkg/uninstall) displayed above.

7. Double-click the file named "M-Audio USB MIDI Support.pkg" - you should now be looking at the following window:

8. Click "Continue" in the welcome screen of the installation program (see above).

9. The following screen will give important information about the driver you are installing.  Click "Continue" after you are done reading this document


10. Select the hard drive you want to install the driver to. A green arrow will appear over the selected hard drive. Then click "Continue".


11. Click "Install" - the driver files will be copied to your computer.


12. You will have to enter your Administrator name and password.  Click OK once your done.


13. The installer informs you that the software (driver) was successfully installed.  Click "Close".


14. Connect your USB MIDI device to an available USB port on your computer.  If you have a Midisport 8x8, also connect the power supply and turn the unit on.

Your M-Audio MIDISPORT USB device is now ready to be used.

15. For Midisport users:

  • Connect the MIDISPORT's MIDI input(s) to the MIDI output(s) of your MIDI controller keyboard(s)
  • Connect the MIDISPORT's MIDI output(s) to the MIDI input(s) of a sound module, or MIDI keyboard with built in sounds.


Once you have completed the installation procedure above, a new icon is placed in the MIDI section of Audio MIDI Setup (AMS).  To verify that the installation succeeded, open AMS by clicking on the "Go" menu (on top of your screen) and select "Utilities".  Then locate and double-click "Audio MIDI Setup".  Switch to the "MIDI Devices" section*.  A new icon with your Midisport's name (e.g. 1x1 or 2x2), or "Keystation" (for Keystation classic devices) should be displayed in light blue color.  The blue color indicates that your computer is communicating with the device.

* Note: In OS X 10.6 Snow Leopard, users may need to go to the Audio MIDI Setup Menu>Preferences>General Tab, and select to open the MIDI window if the MIDI Devices section doesn't appear.


In the rare case that this icon should appear gray (like the IAC Driver shown above), unplug the USB Cable from the device and plug it back in while your computer is running and/or restart your computer.
