Oxygen 49 playing note clusters with one key

My Oxygen 49 plays note clusters when holding down one key, and sometimes sustains a note even after I've stopped pressing any keys. It did this from the very beginning, but not being experienced with MIDI, I figured it was a problem with the way I had Logic configured. After being used less than half a dozen times it ended up in the back of a closet through multiple moves over the course of a few years.

When I took it out recently, it was still doing the same thing. After I looked into this more, it seems like this is a hardware problem and that many people have had similar experiences. Despite the fact that I used (or tried to use) it no more than 5-6 times, it is no longer under warranty, so the email support area is not giving me any options except to take it to a repair place and pay almost what the Oxygen cost me to begin with. This does not seem right, since it didn't work as intended from the beginning and it was only because of my lack of experience with MIDI devices that I assumed it was me and not the keyboard that was the problem, so the warranty ran out without it getting fixed. Has anyone had any successful experiences with resolving this issue without paying $100+? And without losing the $160 that I already put into my M-Audio purchase for nothing?

  • Hey L Lyndes,

    Thanks for posting!

    I'm sorry to hear that! It does sound like there is an internal issue with the key contacts. This is usually resolved by replacing the keybed. We can verify whether your Oxygen is sending rogue MIDI data to your computer with MIDI monitoring software. A MIDI monitor will show you all the incoming data from any MIDI controllers or MIDI interfaces that you have connected to your computer.

    For testing MIDI devices on PC:
    Download MIDI-OX

    This video will get you set up quickly for MIDI input monitoring in MIDI-OX:

    For testing MIDI devices on Mac:
    Download snoize: MIDI Monitor

    Select the Oxygen as a MIDI input source in the monitor and send some data with one key at a time. If you see multiple notes trigger then there is indeed a hardware problem. Warranty and non-warranty claims cannot be handled here on the forum but I can point you in the right direction! Here are a couple of options that you could choose from:

    • Submit a Warranty or Service Inquiry with our Technical Support team by logging onto the M-Audio Support Page. Select Warranty or Service Inquiry from the drop down menu. This will not require a support code.


    • For faster support, call or email your nearest Support Office or International Distributor. Select your country to find the nearest office.

    Make sure to reference or link to this thread to help out the support team.

    I hope this helps! Let me know if you have any additional questions.
