Yamaha S90 ES Short Manual page 10

Depending on the PLG board you may have
access, via the S90 ES front panel, to selecting a
specific parameter to control with the AC selected
here. Look in the PLG boards NATIVE parameter
area.
Understanding how the Controller and the
Parameter ranges work:
Put on your thinking
Remember I mentioned logic – well here we go.
Minimum-to-Maximum controls versus Negative-
to-Positive controls: Consider the Mod wheel
versus the Pitch Bend wheel as an S90 ES
physical control device. One has its zero position
in the middle, while the other is at zero in the
down position. One changes values from minimum
towards maximum, the other above and below a 0
center value. These factors must be considered
when you make an assignment of a parameter to
a physical control.
controllers in these two groups:
Minimum to Maximum Controllers
Modulation Wheel
Foot Controllers: FC1/FC2
Breath Controller

Foot Switch/Sus *min. or max. only
Negative ~ 0 ~ Positive Controllers
Pitch Bend Wheel (self centering)
Assign 1/2 (center détente)
Assign A/B (center détente)
Control Slider 1/2/3/4 (center détente)
Now think about the parameters and the range of
possible values. Some
minimum to maximum (like volume and effect
sends: 0-127) while others move above and below
a center zero point (pan position: L-C-R), and
filter cutoff: -64 more closed, 0 normal, +63 more
open).
This can be an issue if, for example, you assign a
minimum to maximum parameter, like Common
volume 0-127, to a negative to positive
controller like Assign 1.
Here's what happens:
The center position will be 0 volume, while +63,
at the top, will be maximum volume. For all
settings below the center position, 0 through –64,
the minimum volume is sent out, 0. The control
caps...this is tricky.
Think about all physical
parameters go
seemingly only works half the time. You can't hear
less than 0.
Conversely, if you assign a parameter that is
negative to positive to a controller that does not
have a center détente (a minimum to maximum
controller like MW), you may find it difficult to
place it back to neutral.
It is not
negative/positive parameter, like pan position, to
a negative/positive controller like a S90 ES Slider.
In such a case, negative values pan left, positive
values pan right and the center position is center.
Conclusion: Consider the above when selecting a
controller for a specific parameter.
The Control Sliders
There are 4 Control Sliders, CS1-CS4. We need to
talk about their function in Voice, Performance
and Master Keyboard modes.
Why don't the Control Sliders send cc007 in
Voice Mode? The sliders send Element Level via
system exclusive
combine up to four (sampled) elements you have
a slider for each Element. Of course, they do not
send cc007 (Main Volume) in Voice mode – cc007
is main channel Volume and would affect all
components together (common) because they are
all on the same MIDI channel. You would lose
individual control. It would set all Elements to the
same Volume no matter which slider you moved.
Why don't the Control Sliders send cc007 in
Performance Mode? The sliders send Voice
Level again via system exclusive messages –

individual control because a channel message
would set all Voices to the same Volume no
matter which slider you moved. All Voices in a
Performance are on the same MIDI channel.
What about the Control Sliders in Master
Keyboard Mode? The sliders are assignable to
any control change number from 1-95, when you
are setting up a 4-zone setup. You determine
what each slider sends to each corresponding
zone. You determine the MIDI channel and
destination (internal TG or MIDI or both) for each
zone. The default is cc #007 (volume) for each
zone and this is sent out via MIDI (if you want).
