Touch Sensitivity; Voice Set - Yamaha Portatone PSR-640 Owner's Manual

Other Functions (Utility)

Touch Sensitivity

The keyboard of the PSR-740/640 is equipped with a touch response feature that lets you
dynamically and expressively control the level of the voices with your playing strength —
just as on an acoustic instrument. The Touch Sensitivity parameter gives you detailed
control over the touch response feature by letting you set the degree of touch response.
• Set the value with the data dial, the [+/YES] button, the [-/NO] button or the
number buttons [1]-[0].
The greater the value, the more sensitive the keyboard is to your playing strength and the
more dynamic range that can be brought out of the voices.
A setting of "0" results in a fixed touch response, or no level change no matter how hard or
how soft you play the keys. (This setting is good for instrument sounds such as organ or
harpsichord, which normally do not have touch response.) You can also achieve the same
effect by turning touch response off with the [TOUCH] button on the panel (the indicator
turns off).

Voice Set

The VOICE SET feature brings out the best in each individual voice by automatically
setting a range of important voice-related parameters whenever an R1 panel voice is
selected. The parameters that may be set by the VOICE SET feature are listed below. This
function lets you turn VOICE SET on or off, as required.
