Top Panel Descriptions
   Modulation Wheel (Modulation): This is an assignable controller with a default of controlling vibrato or tremolo 
effects assigned to the instrument you are currently playing  This type of real-time controller was originally introduced 
on electronic keyboards to give the performer options such as adding vibrato, just like players of acoustic instruments 
do  If you are using your keyboard as a MIDI controller, the Modulation wheel transmits MIDI modulation (MIDI CC 01) 
messages as it is moved  Some external MIDI devices may not respond to modulation messages, and not all instruments 
respond to modulation data sent from the Modulation wheel  Check the MIDI implementation charts provided with your 
other MIDI equipment or software for modulation details  Details on how to change the function of this wheel can be 
found in the “Advanced Features in Edit Mode” section 
   Headphone Outputs (Phones): These two output jacks accept standard 1/4” TRS headphone plugs, and are rated to 
accept headphones in a broad range of impedances, between 32 and 600 ohms 
   Pitch Bend Wheel (Pitch Bend): The Pitch Bend wheel is used to bend the pitch of a note up or down  This enables 
you to play phrases not normally associated with keyboard playing, including guitar-style riffs  If you are using your 
keyboard as a MIDI controller, the Pitch Bend wheel transmits MIDI pitch bend messages as it is moved  Some external 
MIDI devices may not respond to pitch bend messages  Check the MIDI implementation charts provided with your other 
MIDI equipment or software for pitch bend details  
   Octave < > Buttons (Octave): By default, these buttons apply octave shift to the notes played on the keyboard  
Pressing the Octave > button (right) will shift the notes played on the keyboard up by one octave  When octave shift is 
active (i e  after pressing this button) the LED above this button will light  Pressing the Octave < button (left) will shift the 
notes played on the keyboard down by one octave  Pressing both Octave buttons together will restore the default octave 
(Octave shift = 0)  Any lit LEDs will go out and the keyboard will now transmit MIDI notes that are not octave-shifted 
 
 The Octave buttons can also be assigned to send different MIDI data  This is explained in the “Advanced Features in Edit 
Mode” section
