The Octave buttons allow you to shift the octave of the keyboard up or down to extend the range of the keyboard. Press the OCTAVE +/– buttons to shift the octave up or down a maximum of four octaves. Press the OCTAVE +/– buttons together to reset the octave shift to zero. The octave shift value will be shown under the Oct tag on the second row of the screen.

Note: This adjustment is only for Zone 1 in the current Preset. If you engage zones 2–4 or select another

Preset, the octave shift value will change according to the setting in the zone. Please refer to the sec-

tion Zones on p. 20 for more information.

Transpose Buttons

Press the TRANSPOSE +/– buttons to transpose a note up or down by a maximum of 12 semitones. Press the TRANSPOSE +/– buttons together to reset the transpose shift to zero. The transpose value will be shown under the Trans tag on the second row of the screen.

Note: This adjustment is only for Zone 1 in the current Preset. If you engage zones 2–4 or select another

Preset, the transpose value will change according to the setting in the zone. Please refer to the section

Zones on p. 20 for more information.

Aftertouch

The keyboard features aftertouch. After hitting a key, keep pressure on the key, and the channel aftertouch (value common to all keys) message will be transmitted. You can change the control of the aftertouch in Setup Mode (p. 17). The transmitting port and channel follow the port and channel settings of Zone 1.

Velocity Curve

The keyboard is velocity sensitive. There are ten selectable velocity curves. Refer to Selecting the Keyboard Velocity Curve on p. 18 to understand how to select a curve.

Modulation Wheel

The MODULATION wheel is usually used to add vibrato effects to tones you are playing. The data range of the MODULATION wheel is 0–127. The transmitting port and channel follow the port and channel settings of Zone 1.

PITCH BEND Wheel

The PITCH BEND wheel is used to bend notes played on the keyboard by raising or lowering the pitch. The response and range of the controller is based on the patch or sound source that is being controlled. The pitch bend wheel is spring-mounted and will return to the center position when it is released.

Pedal

The default setting for the pedal input is sustain. You can assign another control to it in the

Setup Mode. The transmitting port and channel follow the port and channel settings of Zone

1. Refer to the section Pedal Setup on p. 19 to learn how to assign the pedal.

Note: Do not step on the pedal when powering on the keyboard as the unit will detect the polarity of the pedal automatically.

Trigger Pads

The keyboard features four assignable velocity-sensitive trigger pads with aftertouch. The factory setting for the trigger pads is to function as drum pads. When you strike the pad, a corresponding icon will appear and its note MIDI message will be transmitted on channel 10. The pad number and the velocity curve number will be shown in the Operation and Data area of the display and the port, channel, pad type, pad mode and note number information will be shown under relevant tags. When you press a pad, and continue to press it, the pad will send a channel aftertouch message depending on how hard you press the pad.

The pads are configured to two pad banks with different settings for each pad, for a total of eight individual pads. Press the PAD BANK button to switch between the two banks. The active bank will be shown on the display. The factory default settings for pads are listed in the

Factory Default Setting table on p. 32. You can select the pad velocity curve, change parameters, or assign other controls to pads in the Setup Mode.

Setting the Channel, Program, MSB, LSB and Port for the Keyboard

Some parameters can be edited from the Performance Mode. Press the PAGE ◀ / ▶ buttons to cycle through the parameters. Use the DATA +/– buttons to edit data. The edited data in the second row of the display will flash. When you have completed making your changes for all items, press the ENTER button to confirm and transmit them together. To cancel your changes, press the MAIN button. All data will be recovered to its original value.
