EG The EG (Envelope Generator) settings determine how the level of the sound changes in time. This lets you reproduce many sound characteristics of natural acoustic instruments-such as the quick attack and decay of percussion sounds, or the long release of a sustained piano tone. Level ATTACK DECAY Key on Sustain Level RELEASE Time Key off [3 ] ATTACK Determines how quickly the sound reaches its maximum level after the key is played. The lower the value, the quicker the attack. 1 [4 ] DECAY Determines how quickly the sound reaches its sustain level (a slightly lower level than maximum). The lower the value, the quicker the decay. [5 ] RELEASE Determines how quickly the sound decays to silence after the key is released. The lower the value, the quicker the decay. Voices VIBRATO Vibrato is a quavering, vibrating sound effect that is produced by regularly modulating the pitch of the Voice. Pitch SPEED DEPTH DELAY Time [6 ] DEPTH [7 ] SPEED [8 ] DELAY Determines the intensity of the Vibrato effect. Higher settings result in a more pronounced Vibrato. Determines the speed of the Vibrato effect. Determines the amount of time that elapses between the playing of a key and the start of the Vibrato effect. Higher settings increase the delay of the Vibrato onset.  EFFECT/EQ Page 1 REVERB DEPTH/CHORUS DEPTH/DSP DEPTH/PANEL SUSTAIN [1 ]/ REVERB [2 ] DEPTH Adjusts the reverb depth. [3 ]/ CHORUS [4 ] DEPTH Adjusts the chorus depth. [5 ] DSP ON/OFF Determines whether the DSP effect is on or off. This setting can also be made from the VOICE EFFECT [DSP] button on the panel. [6 ] DSP DEPTH Adjusts the DSP depth. If you want to re-select the DSP type, you can do so in the "2 DSP" menu explained on page 19. [7 ] PANEL SUSTAIN Determines the sustain level applied to the edited Voice when the VOICE EFFECT [SUSTAIN] button on the panel is turned on. 18 PSR-S975/S775 Reference Manual
