Keys stopped working but pitch bend, modulation, and volume work fine
Text size [-] [+]

Q: The keys on my M-Audio USB MIDI Keyboard stopped working and no longer trigger sounds; however, I do see that MIDI is being received when I use the pitch bend, modulation, or volume slider.

A: You should first attempt to reset your keyboard to factory default settings.  Devices including the Keystation 49e/61es/88es, KeyRig 49, and KeyStudio 49 do not store any settings and are effectively reset by powering off and on.   Axiom users should see this article if only some of the keys are no longer working, and Keystation Pro 88 users should see this article.  If resetting your keyboard doesn't fix the problem, the next step is to test your M-Audio USB MIDI keyboard to confirm that only they keys have stopped transmitting MIDI data


Windows XP/Vista

MIDI-OX is a free, all-purpose MIDI utility program that you can use to test the MIDI Input and/or output of your device.  Download and install MIDI-OX 7.0 from www.midiox.com and follow the steps below to test your device.

1. Launch MIDI-OX.

2. Go to the Options Menu and select MIDI Devices.
 
3. Select your device as the MIDI Input:


Note: A Keystation 49e is used in this example.  Some M-Audio USB MIDI keyboards may show up as USB Audio Device when the Microsoft class-compliant driver is being used in Windows XP.

4. Click OK.

5. Start pressing keys on your M-Audio USB MIDI keyboard.



If any Note On/Note Off messages are received (pictured above), your M-Audio USB MIDI Keyboard is working properly.  Check the MIDI settings and routing in your application.  If no Note messages are received when playing keys, test the volume slider (if available), pitch bend, and modulation wheels.




If MIDI messages are received from the volume slider (if available), pitch bend, and modulation wheels (pictured above), but not from the keys, this is due to a hardware malfunction with the device; please contact tech support to arrange a repair.  If you are located outside of the United States, please contact your local M-Audio Office or M-Audio dealer for repair information.


Mac OS X

 

1. Launch Apple’s AMS (Audio MIDI Setup) utility, this can be used to test  your M-Audio USB MIDI keyboard.  You can find it in Macintosh HD>Applications>Utilities.

2. Click "MIDI Devices" and your M-Audio USB MIDI keyboard should appear.



3. Click the “Test Setup” button (Mac OS 10.3 and higher only). 

Please note the triangles on your MIDI device icon’s bottom end that are pointing to- and away from it. 

4. Send MIDI into the computer by pressing keys on your M-Audio USB MIDI keyboard.  If this causes your Mac to make a “ping” sound (make sure your speakers are on and that you can hear other system alert sounds through them), the arrow pointing towards (upward) your MIDI device icon should – at the same time, light up in blue for a short time. 

If this happens your M-Audio USB MIDI keyboard is working properly.  Check the MIDI settings and routing in your application. 

5. If no MIDI messages are received when playing keys, test the volume slider (if available), pitch bend, and modulation wheels.

If MIDI messages are received from the volume slider (if available), pitch bend, and modulation wheels (pictured above), but not from the keys, this is due to a hardware malfunction with the device; please contact tech support to arrange a repair.  If you are located outside of the United States, please contact your local M-Audio Office or M-Audio dealer for repair information.
