Using Effects; Effect Structure - Yamaha S90 Owner's Manual

In the final stage of programing, you can set the effects parameters to further change the sound's character.

Effect structure

The S90's effect processing features the following
effect units.
System Effects (Reverb, Chorus, Variation)
System Effects are applied to the overall sound,
whether it be a voice, an entire performance setup, a
song, etc. With System effects, the sound of each part
is sent to the effect according to the effect Send Level
for each part. The processed sound (referred to as
"wet") is sent back to the mixer, according to the
Return Level, and output — after being mixed with the
unprocessed "dry" sound. This arrangement lets you
prepare an optimum balance of the effect sound and
the original sound of the parts.
Reverb
The Reverb effects add a warm ambience to the sound,
simulating the complex reflections of actual
performance spaces, such as a concert hall or a small
club. A total of 12 different Reverb types are available.
Chorus
The Chorus effects use modulation to create a rich
ensemble sound — as if one part were being played by
several instruments simultaneously. A total of 25
different Chorus types are available.
Variation
The Variation effects provide a wide variety of sound
transformations and enhancements. A total of 25
different Variation types are available. Variation is not
available in the Voice mode.
Insertion Effects (1, 2)
Insertion effects can be applied individually to each
part. Insertion effects are mainly used to directly
process a single part. The depth of the effect is
adjusted by setting the dry/wet balance. Since an
Insertion effect can only be applied to one particular
part, it should be used for sounds you want to
drastically change. You can also set the balance so that
only the effect sound is heard, by setting Wet to 100%.
The S90 features two Insertion effect systems — one
with a total of 104 internal effect types and the other
with 25.
Plug-in Insertion Effects
This is a special effect system, only available when an
effect-type Plug-in Board (page 22) is installed. Plug-in
Board effects are not available in the Voice mode.

Using Effects

Master Equalizer
Usually an equalizer is used to correct the sound
output from amps or speakers to match the special
character of the room. The sound is divided into
several frequency bands, then by raising or lowering
the level for each band, the correction is made.
Adjusting the sound you play according to the genre—
classical music being more refined, pops music more
crisp, and rock music more dynamic—can also serve to
draw out the special characteristics of the music and
make your performance more enjoyable.
The S90 possesses a high grade five-band digital
equalizer function. The four sliders can be used to
adjust the gain of the four bands (among five).
Example of Effect Settings
Here we'll show an example of editing effect settings
in the Voice Edit mode (page 60). In this example,
we'll change the Insertion1 setting of the Voice Or:
BreathPipe (PRE1: E13) from Thru to FLANGER
(a jet-like sound).
1 Select the Voice Number of the Voice you wish to
edit (Here, Or: BreathPipe=PRE1: E13), then
enter the Voice Edit mode (pages 36 and 60).
2 Press the [COMMON] button to select the
