Top Panel Descriptions

1 . Modulation Wheel (Modulation): This wheel is used to add expressivity to your performance by changing the intensity
of certain effects . The Modulation wheel usually controls vibrato (change in intonation) or tremolo (change in volume) of your
selected sound . The MIDI data range of this wheel is 0 to 127, with 0 being the note-unchanged position (i .e ., the wheel is
rolled downward toward the user) .
Note that the Modulation wheel can be assigned to control MIDI parameters other than modulation (MIDI CC 1) . This topic is
covered in the "Advanced ProKeys Sono Functions in Edit Mode" chapter of this User Guide .
2 . Headphone Outputs (Phones): These two output jacks accept standard 1/4" headphones . The volume of these outputs is
controlled by the Master Volume fader (6) .
3 . Pitch Bend Wheel (Pitch Bend): This wheel lets you create expressive changes in your performances by raising and
lowering pitch . Rolling the Pitch Bend wheel upward will raise an instrument's pitch whereas rolling it downward will lower the
pitch . Note that this wheel is spring-mounted and will return to the center position when released .
4 . Transpose (Data) < > Buttons: In this User Guide, these buttons will be referred to as the Data buttons . By default, these
buttons transpose the keyboard in half-step increments . Pressing the Data > button (right) will shift the notes played on the
keyboard up one half-step (for example, D becomes D-sharp) . When shifted upward, the LED above the right Data button will
illuminate . Pressing the Data < button (left) will shift the notes played on the keyboard downward (for example, G becomes
G-flat) and the LED above the left Data button LED will illuminate . Pressing both Data buttons together will "center" the
keyboard and restore the default transpose state (Transpose shift = 0) and any illuminated Data button LEDs will turn off .
The Data buttons can also be assigned to send different MIDI messages or control other features on ProKeys Sono . This is
explained in the "Advanced ProKeys Sono Functions in Edit Mode" section of this User Guide .
5 . Edit Mode Button (Edit Mode): When this button is pressed, the associated LED illuminates and the keyboard enters "Edit
mode . " While in this mode, the keys on the keyboard no longer transmit MIDI notes, and are instead used to select advanced
functions and enter data . The "Advanced ProKeys Sono Functions in Edit Mode" section of this User Guide contains more
detailed information about Edit mode . Press this button again to exit Edit mode .
6 . Master Volume Fader (Master Volume): The Master Volume fader controls the level of the main outputs (17) as well as
the headphone outputs (2) .
7 . Microphone Gain Knob (Mic Gain): This knob controls the gain level of the Microphone input . The signal (green) LED
illuminates when signal is present at the microphone input (i .e ., incoming audio signal is greater than -20dB) . The peak (red)
LED illuminates when incoming audio signal is clipping (distorting) and indicates that the Microphone Gain knob should be
turned down .
