Troubleshooting

General

Here are answers to common questions you may have, using your Keystation keyboard:

Problem 1: My M-Audio hardware suddenly stopped working after having performed fine since

installation.

Solution 1: Switch off the unit and let it sit for 10 seconds. Then restart your computer and try again. If the

problem persists you may have to reinstall drivers for the unit.

Problem 2: I have plugged a sustain pedal into my M-Audio keyboard, but it works the wrong way

around.

Solution 2: 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. So if you want the sustain pedal to be off when it

is not depressed, make sure the pedal is not depressed when you power up.

Problem 3: When I press a key, there is a delay before I hear any sound.

Solution 3: This delay is known as latency. Latency with MIDI signals is due to the software application you

are using. MIDI data is simply control data. The MIDI data is read by your software. The software then

completes a large number of complex calculations in order to produce the sound you hear—all this takes

time.

We strongly recommend a proper audio interface. Refer to m-audio.com for a selection of options. If you

already have an adequate audio interface, try reinstalling the latest drivers for the audio interface, or try

reducing the buffer sizes of the audio drivers.

MIDI Functionality

The Keystation keyboards have been designed to make working with MIDI on your computer as simple as

possible. Nonetheless, you may still experience some difficulties. In many cases, the keyboard is not at fault;

the problem lies with the receiving device. To counter this, there are two useful MIDI functions:

All Notes Off and Reset All Controllers.

All Notes Off

If you find there are hanging notes that you cannot stop playing, send an “All Notes Off” MIDI message by

performing the following:

1. Press the Advanced Functions button to engage Edit Mode.

2. Press the black key representing “ALL OFF.”

3. Edit Mode will disengage, eliminating any hanging notes.

Reset All Controllers

If you find there is an effect on a voice that you do not want, rather than having to isolate and identify that

effect, you can send a “Reset All Controllers” MIDI message by performing the following:

1. Press the Advanced Functions button to engage Edit Mode.

2. Press the black key representing “RESET.”

3. Edit Mode will disengage, eliminating all effects.

Factory Reset

1. Power off Keystation.

2. Hold down the buttons "ADVANCED", "OCT+", and "OCT-" simultaneously, until step 4.

3. Power on Keystation.

4. Release the three buttons.

The Keyboard is now back to the factory default settings.
