Expression & Effects s Harmony ... Press the [HARMONY] button to turn the HARMONY effect on or off. When HARMONY is on (indicator lit), playing single notes or chords on the right-hand section of the keyboard produces automatic harmony matched to the accompaniment chords. The harmony function can be turned on when AUTO BASS CHORD accompaniment is off, but in this case the harmony produced will consist only of unison and/or octave notes. NOTES • The type of harmony produced can be selected via the HARMONY EASY SETTING display, or via the HARMONY function display. See page 114 for details. • The harmony is based on the ABC chords, and is added to the highest note played except when only the LEAD voice is on, in which case the harmony notes are added to the last note played. • The HARMONY feature cannot be turned on when the FULL KEYBOARD ABC mode is selected. TOUCH HARMONY SUSTAIN RESPONSE REVERB CHORUS DSP EFFECT s Sustain ... Press the [SUSTAIN] button to turn the sustain effect on or off. When on (indicator lit), extra sustain is applied to the selected voice. When sustain is applied via a footswitch, however, the panel [SUSTAIN] button will not function. NOTES • Sustain can be applied to any combination of the LEFT, RIGHT 1, RIGHT 2 and LEAD voices via the SUSTAIN BUTTON parameter available via the SUSTAIN EASY SETTING display or the CONTROLLER function display. See page 104 for details. • The sustain effect may not produce the same effect for all voices. TOUCH HARMONY SUSTAIN RESPONSE REVERB CHORUS DSP EFFECT s Touch Response ... The touch response function turns the PSR-4000's keyboard velocity response on or off. Normally, touch response should be turned on - the [TOUCH RESPONSE] button indicator should be lit - to allow normal dynamic control via the keyboard (i.e. the harder the keys are played, the louder the sound). In some cases, however, you might want to turn touch response off (indicator off). For example, most organs have no keyboard velocity response, so touch response can be turned off for greater realism when playing organ type voices. Touch response can also be turned off to create a constant-volume sound with any voice. Use the [TOUCH RESPONSE] button to turn touch response on or off as required. TOUCH HARMONY SUSTAIN RESPONSE REVERB CHORUS DSP EFFECT NOTES • Touch response sensitivity, off level, and voice assignments can be set via the TOUCH EASY SETTING display, or via the CONTROLLER function display. See page 107 for details. 33
