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.
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
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
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.
