Chapter Three How the Effects function
On the GP·16, sounds are created as a result of the values that are set for each effect
unit. Here explained is the manner in which these parameters function in producing
effects.
• In this chapter, the sound input to an effect unit is referred to as the "direct sound",
whereas the sound which has been altered by, and is output from the effect unit is
referred to as the "effected sound. "
<11-1> COMPRESSOR
While suppressing high level input, it increases the gain
tor weaker input, thus havmg an averaging effect on
. volume. It is
a
digital compressor which does not distort
the anginal sound, and provides long sustamed effects.
Setting used to adjust the tone of fhe effected sound.
"+" Boosts (increases) the amplitude of the upper
sound range.
"±O" The tone is unchanging and flat.
- Cuts (attenuates) the amplitude of the upper
sound range

VALUE-SO-50
Setting which determines the strength of the attack at the
moment of picking (when string is played). With higher
values, the attack for each and every note becomes
more noticeable, thus a sound that is more clear-cut is
produced.

While increasing the gain for weaker input. determines
the range (time) over which amplitude will remain steady.
As higher values are set, the sustain becomes longer.
With the value set low, it can also be used to tunction in
a manner
similar to
a limiter, since it then serves mainly
in suppressing higher levels of input.

Should be set so there is no difference in amplitude when
an effect is tumed on and off. The higher the value is set.
