Trouble-Shooting

My M-Audio hardware suddenly stopped working after having performed fine since installation.

Switch off the unit and leave for 10 seconds. Then restart your computer and try again. If the problem persists you may have to re- install drivers for the unit.

My drivers are listed in the Device Manager and are said to be working, but the keyboard is not recognized in any software.

Windows 2000 and XP have a limitation to how many MIDI device drivers you can have installed at one time. However, the computer will not give any indication that you are using the maximum number of drivers and the drivers will install as if there is not a problem. To remedy this, go to the driver download section of our website at http://www.m-audio.com/index.php?do=support.drivers and download the MIDIFix utility.

I have plugged a sustain pedal into my M-Audio keyboard, but it works the wrong way around.

The polarity of the sustain pedal is calculated by the keyboard when it is powered up. On power up, the sustain pedal is assumed to be in the off position. If you want the sustain pedal to be off when it is not pressed, make sure the pedal is not pressed when you power up.

When I press a key, there is a delay before I hear any sound.

This delay is known as latency. Latency with MIDI signals occurs as a result of the softsynth you are using. MIDI data is simply control data that is read by a softsynth, which must complete a large number of complex calculations in order to produce the sound you hear. This process takes time.

If you are experiencing a noticeable delay between playing a note and hearing it, you are most likely using a software-based synthesizer and outputting audio through an audio card that is currently running on a less efficient driver. Try switching to the ASIO driver for your sound card. If your sound card allows you to adjust the buffer settings, lower them until the latency is acceptable.

Caution: Electrostatic Discharge, Electrical Fast Transient and Conducted RF interference may cause the unit to malfunction. In the case of such an occurrence, unplug the unit and plug in again to restore normal operation.
