Tuning; Touch Response - Yamaha PORTATONE PSR-248 Mode D'emploi

Tuning

Tuning determines the fine pitch setting of both the main voice and the bass/chord accompaniment
of the selected style. It also determines the pitch of the songs and the Multi Pads. This allows you to
accurately match the tuning with that of other instruments. The Tuning settings can be adjusted over
a range of ± 50 (approx. ± 0.5 semitones).
Select the Tuning function in the Overall menu.
Press one of the OVERALL s/t buttons, repeatedly if necessary, until "Tuning" appears in the
display.
Change the value.
Use the OVERALL +/- buttons to increase or decrease the Tuning
value. Holding down either button continuously increases or
decreases the value.
Restoring the Default Tuning Value
If you've changed the Tuning setting, you can instantly restore the default
setting of "00" by pressing both OVERALL +/- buttons simultaneously (when
Tuning is selected in the Overall menu).

Touch response

The PortaTone features a Touch Response function that gives you dynamic, expressive control over
the volume of the voices. The Touch Sensitivity parameter lets you set the degree of Touch Response.
To turn on Touch Response, press the TOUCH button.
Change the Touch Sensitivity value.
Simultaneously hold down the TOUCH button, and press
the appropriate numbered button on the numeric keypad:
1, 2, or 3.
A setting of "1" results in a narrow dynamic range, no
matter how lightly or strongly you play the keys. A setting
of "2" provides a normal dynamic range from soft to loud,
while "3" (default setting) results in a wide dynamic range
that lets you play from very soft to very loud.
