As many users of modern MIDI keyboard controllers rely heavily on portability, it’s fair that the mobile M-Audio Oxygen 25 MK IV USB is in contention. One of the more appealing features of portable of this 25 key midi controller is the kind of software it comes with. After clicking on the app’s USB MIDI button, the app just shuts down. Hope this is fixed in the not-to-distant future as MIDI keyboard control is crucial for using this app!
This guide covers basic troubleshooting steps to determine whether your USB MIDI device is recognized, and working properly on a Mac computer.

Testing to see if a MIDI device is recognized on Mac

- With the MIDI Studio window open, plug in your USB/MIDI keyboard or controller. Once the device is plugged in and recognized it will appear in the window as solid. If the device is grayed out it is currently unavailable. If your device is not listed or grayed out you may want to try a different USB cable and or USB port.
In the example above you can see that the Numark USB Audio Device is plugged in and recognized. The Keystation Mini 32 is either not plugged in or not recognized.
Testing to see if MIDI devices are transmitting data using MIDI Monitor
What is MIDI Monitor?
Midi Monitor is a free utility for Mac OS X which displays MIDI signals in a variety of formats. It can watch both incoming and outgoing MIDI streams, and can filter them by message type and channel. Musicians will find it handy for tracking down confusing MIDI problems. Programmers can use it to test MIDI drivers and applications. MIDI Monitor is free to download and use.
- Download, and Install MIDI Monitor.
- Open Midi Monitor.
- Click on the Sources tab to view MIDI devices. Confirm that your USB/MIDI device is listed.
- Once you confirm your MIDI device is connected and listed. Play any key(s) on your keyboard/controller to confirm each button or key is sending data to your computer. If you device is working you will see a message with data like below. The device is not sending data you may have a hardware issue. Contact the hardware manufacture for further support.
What to do if your MIDI device is not connecting to your Mac
Often, after an update or migration, you will need to 'refresh' certain MIDI devices. This is done quickly and easily in your Mac's Audio MIDI Setup.
- On your Mac, navigate to Utilities>Audio MIDI Setup
- Go to Window>Show MIDI Studio
- Make sure your MIDI device is unplugged
- After you've unplugged your MIDI device, click on it and choose Remove Device
- Plug your MIDI device back into your computer
If the above steps do NOT resolve your issue...
- Empty the contents of the following two folders by moving their files into to two new folders on your desktop:
Macintosh HD > Library > Audio > MIDI Drivers
Macintosh HD > Users > [Your User Name] > Library > Audio > MIDI Drivers
Note: the second location above is hidden on Mac OS X 10.7 and above. To access it see these instructions.
- These are the places where third-party MIDI drivers are stored. If they have become corrupt, or they haven't been installed correctly, removing them and starting over may help.
- Restart your computer.
- Try your MIDI device again.
- If the symptom has been resolved, you should...
- Reinstall each of these drivers by visiting the home page for the respective device manufacturers. Note, if your MIDI device is Class Compliant, it doesn't require any extra drivers to be installed.
- Find and download the latest drivers for the product(s), and install them.
- Confirm all of your devices now work properly, then trash the files you had moved from your MIDI Drivers folder to your desktop.
Sometimes it can be really hard to be sure if your MIDI keyboard controller or other your USB-MIDI interface is working correctly, particularly if you are using it with complicated software. My suggestion is to separate the two things! Test that the hardware is working OK first. Use your computer’s control panel then test the device with a MIDI diagnostic tool.
Once you can see the MIDI device is working you know that you need to work on the software configuration. Tip: Make sure you install, connect and turn on your MIDI controller first, then start up the software you want to use. Some software just won’t find devices if you turn them on after starting up the software. The video below will take you through some testing basics, then read on for links and more information. If you want a bit more info, then you might find our basic guide on what is MIDI helpful.
Which Diagnostic Tool?
If you are using Windows, then download MIDI-Ox, it’s a fantastic piece of software that shows the stream of MIDI data on your screen so you can check every key, fader, pad and wheel on your MIDI keyboard and be sure they are all working OK. Download it here:
MIDI-Ox MIDI diagnostic tool.
Then if you want a step-by-step guide on how to use it, this page on the M-Audio support portal is great, with easy to follow screen shots. Although it is referring to an M-Audio device you can use this software with any MIDI keyboard or interface.
If you are on a Mac then the SNOIZE MIDI Monitor software does a similar job and they have nice documentation on their site on how to use it.
What If The MIDI Keyboard Isn’t Working?
If you still think the keyboard is not connecting correctly, then there is a useful post here on the Numark site which will help you to troubleshoot your plug and play device. Especially in Windows the native drivers can be missing or corrupted and may need to be re-installed.
If your device is not plug and play then you will need to go to the manufacturer’s site and download the correct drivers. NEVER do a ‘google search’ for drivers – there are lots of dodgy sites out there which will try to tempt you to download all kinds of things from them. Instead, go to the official site of the manufacturer of your particular device and navigate to their support/download page directly. The best manufacturers (Alesis, M-Audio, Numark, Roland, Korg, Samson etc) have telephone support as well, so take advantage of it. But do work through the above steps first!
