Yamaha KX25 Manuel D’Utilisation

Use these buttons to shift the note range of the 
keyboard by octave (three octaves, up or down). 
The initial default setting (no shift) is recalled by 
pressing both the buttons simultaneously.

The current octave range can be confirmed via the 
status of the LED lamp above the button.

You can select the desired Velocity Curve which 
determines how velocities are applied according to 
your playing strength. Use the VELOCITY CURVE 
[DEC] and [INC] buttons to select the desired 
Velocity Curve.

The following Velocity Curves are available:

Press the VELOCITY CURVE [DEC] and [INC] 
buttons simultaneously to select “Fix.” The Fix 
setting lets you play the notes with a fixed velocity 
no matter how hard or soft you play the notes.

You can set the fixed velocity by pressing one of 
the VELOCITY CURVE [DEC] and [INC] buttons. 
Pressing both the buttons simultaneously exits from 
this status (Fix setting) to the last selected Velocity 
Curve.

NOTE

You can reverse the LED status (on or off)

about how to reverse the LED status (on or 
off), refer to “Utility Settings” on page 36.

Note names of the keyboard
The range of the keyboard is indicated by note 
name, as described below.

The note name assignment above depends on the 
initial default setting of the KX. This assignment 
can be shifted by using the [OCTAVE] buttons.

Press this to shift the 
octave range down.

Press this to shift the 
octave range up.

Restores the default octave setting.

This curve produces high velocity values 
even for low playing strength. Select this if 
you want a high volume even when you 
play softly.

This curve produces relatively high velocity 
values even for low playing strength. It is a 
more moderate curve than Soft 2 above.

This is a normal, linear curve that has a 
one-to-one correspondence between your 
playing strength and the resulting velocity.

This curve produces relatively low velocity 
values even for high playing strength. 
Select this if you don’t want the volume to 
change much when you play strongly.

This curve produces low velocity values 
even for high playing strength. It is a more 
extreme curve than Hard 1 above. This 
curve is also the optimum Velocity Curve for 
use with the HALionOne VSTi.

NOTE

From the Utility display (page 26), you can 
select a Velocity Curve and specify a 
specific velocity value to be used when Fix 
is selected. For details, refer to “Utility 
Settings” on page 36.
