Quick Guide Create Original Sounds x Effect Reverb Chorus Send Level Send Level Reverb reproduces the acoustic ambience of a concert hall or club, while chorus produces a layered "multi-instrument" effect. Knob A adjusts the depth of the reverb effect, and Knob B adjusts the depth of the chorus effect. c EG (Envelope Generator) Attack Time Release Time 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. Level Sustain Level ATTACK DECAY RELEASE Time Key Played Key Released 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). v Style Filter Filter Filter Cutoff 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 pre- ceding 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. Owner's Manual 23
