Modulation Wheel Assignment
It is possible to assign MIDI effects to the Modulation Wheel. Some useful effects are: MIDI CC 01 (Modulation),
MIDI CC 07 (Volume), MIDI CC 10 (Pan), and MIDI CC 05 (Portamento). There are 132 effects in total. However, for
these effects to have any affect on the sound, the receiving MIDI device must be able to read and respond to these
MIDI effect messages. Most devices will at least respond to volume, modulation, and pan data.
To assign an effect to the Modulation Wheel:
1. Press the Advanced Functions button to engage Edit Mode.
2. Press the black key representing "WHEEL."
3. Use the Numerical Data Entry keys to enter the number of the effect you want to assign to the Modulation
Wheel.
Instead of entering in the value number, you can cycle through each effect one at a time using the "+" and
"-" buttons. Once the correct value has been selected, press the ENTER key.
If you have made an error while entering the numerical data value, you can press the CANCEL key to exit Edit Mode
without changing the effect assigned to the Modulation Wheel.
Note that each time the keyboard is turned off, the data assigned to the Modulation Wheel will be lost. Each time the
keyboard is powered up, the Modulation Wheel will be assigned to modulation (effect number 01) by default.
For the sake of example, we will assign effect number 10 (pan, or balance) to the Modulation Wheel.
1. Press the Advanced Functions button to engage Edit Mode.
2. Press the black key representing "WHEEL."
3. Press "1."
4. Press "0" so you have entered "10."
5. Press "ENTER."
Directional Buttons and Transport Controls
The directional buttons and transport buttons use the Mackie Control or HUI protocols to control certain functions in
software that support them.
To select which protocol these buttons use to communicate with your software:
1. Press the Advanced Functions button to get the keyboard into Edit Mode.
2. Press the key representing MACKIE/HUI.
Note: "+" and "-" LEDs will be lit green when in Mackie mode, or red when in HUI mode.
3. Press Enter.
Note: Your software must also be set to receive commands from an external device (i.e., Keystation 49es)
using the Mackie Control or HUI protocol. Mackie and HUI controls are sent on Virtual Port 2.

Troubleshooting

General
Here are answers to common questions you may have, using your Keystation 49es 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.
