MIDIFlex 4

We are aware of an issue with port routing the MIDIFlex4 MIDI Interface, which occurs in MacOS 14 (Sonoma) and iOS 17. As a result, data which is routed to Port 3 and Port 4 will be passed through Outputs 1 and 2.

Our contact at Apple has told us that the problem will be addressed in OS updates as it occurs with a number of other MIDI interfaces and controllers.

Update: This issue is fixed in MacOS Sonoma 14.4 and iOS 17.4.

If you are using MIDIFlex 4 in MacOS Sonoma 14.3.1 or earlier you will need to remove the MIDIFlex 4 icon from the MIDI Studio window in Apple’s Audio MIDI Setup app, so the configuration can be refreshed. Please follow the steps below:

  1. Open a Finder window
  2. Open the ‘Go’ menu at the top of your screen
  3. Select ‘Utilities’
  4. Double-click on ‘Audio MIDI Setup’ (look for the keyboard icon)
  5. Go to the ‘Window’ menu at the top of your screen and select ‘Show MIDI window’. If it says ‘Hide MIDI window’ then you should already see the ‘MIDI Studio’ window
  6. If you do not see Panorama’s icon, scroll over or expand the window, as the icon may be hidden
  7. Disconnect the MIDIFlex 4.
  8. The MIDIFlex 4 icon should now be grayed out. Click on it to select.
  9. Press the ‘Delete’ or ‘Backspace’ key on your computer keyboard. The MIDIFlex 4 icon is now removed.
  10. Reconnect the MIDIFlex 4. A new icon appears and you are now ready to check that outputs 3 and 4 are working again.
