answer you are looking for, please feel free to contact M-Audio technical support for further assistance.

Problem 1: My KeyStudio suddenly stopped working after having performed ﬁne since installation.

Solution 1: Close any music applications you are using, switch KeyStudio off, and restart your computer. Once your computer

has completely restarted, switch KeyStudio back on.

Problem 2: I have connected a sustain pedal to my M-Audio keyboard, but its function is reversed.

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.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.Alsochecktoseeifthereisapolarityswitchonyourfootpedal.Itispossibletousethis

switch to change foot pedal polarity as well. Another way to reverse the sustain pedal’s polarity is to keep it pushed while

powering on your KeyStudio keyboard.

Problem 3: KeyStudio does not trigger sounds in my music software application.

Solution 3:BesureKeyStudioisselectedastheMIDIinputdevicewithinyoursoftware.

Problem 4: I cannot locate the KeyStudio USB keyboard in my software’s MIDI devices dialog box.

Solution 4: KeyStudio requires a powered USB port. Try plugging KeyStudio into a different USB port or powered USB hub

connected to your computer.

Problem 5: My synthesizer always recalls the sound next to the program number that I have sent to it from KeyStudio.

For example, if I send a program change with the number 40 (Violin), my software loads sound number 41 (Viola).

Solution 5:SomeGeneralMIDImodulescounttheirsoundpatchesfrom1–128insteadof0-127.Bothmethodsare

common.Asaresult,anddependingonthesoundmoduleyouuse,theremaybeanoffsetof+/-1betweenthesentprogram

change number and the recalled sound patch.
