• TOUCH This button turns the touch response of the keyboard on or off. When off, the same volume is produced no matter how strongly or softly you play the keyboard. • SUSTAIN When this Sustain function is on, all notes played on the keyboard with right-hand part (RIGHT 1 and 2) have a longer sustain. • MONO When this button is on, the part's Voice is played monophonically (only one note at a time). Using the MONO mode lets you play single, lead sounds (such as brass instruments) more realistically. It also lets you expressively control the Portamento effect (depending on the selected Voice) by playing legato. When this button is off, the part's Voice played polyphonically. • DSP/DSP VARI. With the digital effects built into the instrument, you can add ambience and depth to your music in a variety of ways - such as adding reverb that makes you sound like you are playing in a concert hall. The [DSP] button is used to turn the DSP (Digital Signal Processor) effect on or off for the currently selected keyboard part. Although many of the Voices have been automatically set to play the certain DSP types to match the particular Voice, you can change the type. On the Voice Selection display, select [6 ] (VOICE SET) TAB [E][F] EFFECT/EQ  [A]/[B] 2 DSP. For details, refer to the Reference Manual on the website. The [DSP VARI.] button is used to change between variations of the DSP effect. You could use this while you play, for example, to change the rotating speed (slow/fast) of the rotary speaker effect. NOTE Portamento is a function that creates a smooth transition in pitch from the first note played on the keyboard to the next. Applying Harmony to Your Right-hand Melody (HARMONY/ECHO) Among the Voice Effects, Harmony is one of the most impressive. When the Harmony/Echo is on, the Harmony effect is applied to the right-hand Voices depending on the chord played with your left hand. 1 Turn the [HARMONY/ECHO] button on. 2 Turn on both the [ACMP] button and [SYNC START] button (page 43) and make sure that the RIGHT 1 part is on (page 32). 3 Play a chord with your left hand to start the Style (page 44) and play some notes in the right-hand range of the keyboard. NOTE Depending on the harmony/echo type, harmony will be applied even when the [ACMP] button is off. Split Point Chord section In this example, harmony notes in the scale of C major (the chord played in the left hand) are automatically added to the notes played in the right-hand range of the keyboard. You can also use the Harmony effect with the Style stopped. Simply hold down a chord with your left hand and play a melody with your right. Although many of the Voices have been automatically set to play the certain Harmony/Echo types to match the particular Voice, you can change the type via [FUNCTION]  [G] (HARMONY/ECHO). For details, refer to the Reference Manual on the website. 40 PSR-S950/S750 Owner's Manual
