If your Midi Fighter 64 isn't detected by the MF Utility please follow the steps below:
- Download and install the latest version of the MF Utility for your OS: Windows / OS X
- Download this file and unzip it, it will give you a "MF64_RESCUE.hex" file. Don't open it, you'll do that in step 6.
- Connect your 64 to a USB port (do NOT use a USB hub) while holding down the bottom-left arcade button. You'll see a blue checkerboard pattern across the controller to indicate
- Close any music related software that can handle MIDI such as Traktor, Maschine, Ableton, SeratoDJ, VirtualDJ, FLStudio, etc and then run the Midi Fighter Utility.
- Click "Tools>Midi Fighter>Load Customer Firmware>For a 64"
- Navigate to the file you downloaded in step 1 and click "Open".
- The utility will now flash your 64 and it should now behave correctly.
If your 64 sends MIDI to other software but the MF Utility doesn't recognize it in OS X do as follows:
- With your unit connected directly to your computer go to Applications>Utilities and open the Audio MIDI Setup application
- Once that is open click on Window>Show MIDI Window
- If you see your Twister greyed out then select it and click on Remove Device
- Finally click on Rescan MIDI and your fighter should work properly
Note:If your computer detects it as a Generic MIDI Device then double click it and change the Device Name to "Midi Fighter 64".
