1. DC Power Adapter Input: If you do not wish to power Keystation through the USB connection and are
using the MIDI connector to trigger an external sound module, connect a 9V DC, 200mA, center-positive
power adapter (sold separately) here.
2. USB Port: The USB port delivers power to the keyboard and transmits MIDI data when connected to a
computer to trigger a software synth or MIDI sequencer.
3. MIDI Out: Use a five-pin MIDI cable (sold separately) to connect this jack to the MIDI IN of an external
sound module or to the MIDI In of a synthesizer.
4. Sustain Pedal Input: This socket accepts a momentary-contact foot pedal (sold separately). When
pressed, this pedal will sustain the sound you are playing without having to keep your fingers pressed
down on the keys.
NOTE: The polarity of the sustain pedal is determined by the keyboard upon startup. When Keystation is
powering up, the sustain pedal is assumed to be in the "up" (Off) position. It is important that the sustain
pedal is not pressed during startup, otherwise the pedal will reverse its operation, and notes will sustain
when the pedal is not pressed.
NOTE: A foot pedal can be used for sustaining the sound that you are playing, without having to keep
your hands on the keyboard (just like the sustain pedal on a piano).
You can plug a foot pedal of any polarity, sold separately, into the foot pedal input on your M-Audio
keyboard. The keyboard will automatically detect the correct polarity when powering up. If you want to
reverse the polarity, simply depress the pedal when you switch on your keyboard.
5. Expression Pedal Input: Connect a 1/4" TRS expression pedal (sold separately) to this input for
adjusting the volume vibrato, or reverb depth of an instrument patch.
6. On/Off Switch: Use this switch to power the device on or off.
Advanced Functions
In addition to setting an octave shift, the two octave "+" and "-" buttons discussed earlier in the manual under
the section "Octave Buttons" can also be used to control one of six MIDI functions.
The first 6 labeled black keys are used to select the function of the octave buttons. Some of the functions that
these keys can be used for cannot send out a value less than 0. When used to control these functions, both
LEDs above the buttons will remain on, regardless of the current setting of that function.
To select an alternate function:
1. Press the Advanced Functions button, putting the keyboard into Edit Mode.
2. Press the black key that represents the function you want. Edit Mode will finish as soon as you have
selected the function and you will be able to play notes again.
