Appendices
The effects of AMS on various param-
eters, and example applications
We'll describe some examples of using alternate modula‐
tion.
Note: The parameter names and values used in these expla‐
nations can be viewed and edited in microSTATION Editor/
Plug‐In Editor.
Pitch (page 28)
Pitch can be controlled by the Common LFO, filter/amp EG,
controllers, or tempo etc.
• If you select Filter EG or Amp EG as the AMS and set
Intensity to +12.00, the pitch will change up to ±1 octave
in synchronization with the EG.
• If you select Tempo as the AMS and set Intensity to
+12.00, doubling the tempo (based on =120.00) will raise
the pitch one octave, and halving the tempo will lower
the pitch one octave.
Pitch EG (page 31)
Pitch EG intensity can be controlled by the Common LFO,
keyboard tracking, controllers, or tempo.
• If you select JS +Y:CC#01 as the AMS and set Intensity to
+12.00, moving the joystick in the +Y direction will
gradually increase the effect of the Pitch EG to a
maximum of ±1 octave. If Intensity has a negative value,
the effect of the Pitch EG will be inverted.
LFO 1/2 (page 52)
Pitch modulation intensity of the LFO1/2 can be controlled
by the Common LFO, an EG, keyboard tracking, controllers,
or tempo etc.
• If you select EG as the AMS, the pitch change width of
LFO modulation etc. can be controlled in synchroni‐
zation with the level changes of the EG. With positive (+)
settings of Intensity, the vibrato effect will gradually
deepen as the EG level rises, or gradually lessen as the
EG level decreases. With negative (–) settings of
Intensity, the LFO phase will be inverted.
• If a controller such as a foot switch connected to the
DAMPER/PEDAL/SW1 or PEDAL/SW2 jack is selected
as "AMS," you can apply a pitch/vibrato effect by
turning on the foot switch only when you want the
effect.
Filter (Cutoff) Frequency (page 37)
The cutoff frequency of filter A/B can be controlled by the
pitch/amp EG, Common keyboard tracking, controllers, or
tempo. Use the Filter Modulation 1 (2) page Filter A/B Mod‐
ulation (page 38) to set AMS and Intensity for Filter A or B.
• If you select JS X as the AMS1 or AMS2 and set Intensity
to a positive (+) value, moving the joystick toward the
right will raise the cutoff frequency, and moving it
toward the left will lower the cutoff frequency. Negative
(–) settings will have the opposite effect.
• If you select the same controller as an AMS1 or AMS2
and set separate intensities for Filter A (Low Pass Filter)
Intensity and Filter B (High Pass Filter) Intensity, you can
use a single controller to simultaneously control the
cutoff frequencies of both filters.
124
Resonance (page 37)
You can use the EG, LFO, keyboard tracking, controllers, or
tempo etc. to control the resonance level.
• If you select Filter KTrk or Amp KTrk as the AMS, you
can use the filter or amp keyboard tracking settings to
control the resonance level. For example if the amp
keyboard tracking parameters Ramp BtmLo and Ramp
HiTop are set to positive (+) values, Amp KTrk is selected
as the AMS, and Intensity it set to a positive (+) value,
playing toward either end of the keyboard will cause
amp keyboard tracking to increase the volume, and AMS
to raise the resonance level.
• You can select a controller as the AMS, and apply
resonance when desired by using the controller.
• You can select Common LFO, LFO1 or 2 as the AMS, and
use the LFO to control the resonance level.
Output (page 37)
You can use the EG, LFO, keyboard tracking, controllers, or
tempo etc. to control the output level of Filter A/B.
• Set filter routing ("Routing") to Parallel, and specify the
desired filter type for each filter A and B. Choose LFO as
"AMS" for filters A and B, and set "Intensity" to +99 and
‐99 respectively. This allows the LFO to cyclically
crossfade between the outputs of filters A and B.
Filter EG Intensity (page 39)
Filter EG intensity can be controlled by the Common LFO,
Common keyboard tracking, a controller or tempo etc. You
can use Intensity to A and Intensity to B to independently
specify the intensity for Filter A and B.
• If you select JS –Y (CC#02) as the AMS and set Intensity
to A and Intensity to B to a positive (+) value, moving the
joystick in the –Y direction will gradually increase the
effect of the Filter EG. If you set Intensity to A and
Intensity to B to a negative (–) value, the effect of the
Filter EG will be inverted.
• If you select JS X as the AMS and set Intensity to A and
Intensity to B to a positive (+) value, moving the joystick
toward the right will gradually increase the effect of the
Filter EG. Moving the joystick toward the left will
gradually increase the effect of the Filter EG with an
inverted phase.
