Create Original Sounds c EG (Envelope Generator) Envelope Generator effects determine how the level of the sound varies over time. You can make the attack faster for a more percussive sound or slower for a violin-like sound, for example. Or you can lengthen or shorten the sustain to most ideally match the music. Attack Time Release Time Knob A adjusts attack time (the amount of time it takes the sound to reach maximum level when a key is played). Knob B adjusts release time (the amount of time it takes for the sound to decay to silence after a key is released). Level Sustain Level ATTACK DECAY RELEASE Time Key Played Key Released v Style Filter Filter Cutoff Filter Resonance In this case the knobs apply the filter effect to the style being played. Knob A and Knob B have the same functions as for "z Filter" described on the preceding page. b Style Tempo Tempo -No Effect- Knob A adjusts the tempo of the style and arpeggios. Rotating the knob clockwise increases the tempo while rotating it counterclockwise decreases the tempo. The knob's center position produces the initial default tempo. 20 PSR-E413 Owner's Manual
