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. q Voice Set Parameter List • Voice R1 (Volume, octave, pan, reverb depth, chorus depth, DSP depth*) • Voice R2 (Voice number, volume, octave, pan, reverb depth, chorus depth, DSP depth*) • DSP on/off, type, return level and FAST/SLOW on/off • Harmony Type, Volume, Part • DSP1-3 dry/wet (PSR-740) • Multi Effect connection (PSR-740) * PSR-640 only • Turn Voice Set ON or OFF by using the data dial, the [+/YES] button or the [-/NO] button. 136 134
