3–2: Filter 1 Mod (Filter 1 Modulation)
29
JS (X) (Joy Stick (X)) [–99…+99]
With positive (+) settings, moving the joystick to the right will raise the cutoff frequency and
brighten the sound.
With negative (–) settings, moving the joystick to the right will lower the cutoff frequency and
darken the sound.
Aftertouch [0…99]
The operation of this parameter will depend on the filter selected by the Type setting of “3–1: Filter
1 A/B.”
For example with a Low Pass filter, positive (+) settings of this parameter will cause the cutoff fre-
quency to be raised when you press down on the keyboard, brightening the sound.
With a setting of Low Pass, negative (–) settings of this parameter will cause the cutoff frequency
to be lowered when you press down on the keyboard, darkening the sound.
Alternate Modulation
AMS (Alternate Modulation Source) [OFF…Tempo]
Select the source which will control cutoff frequency modulation for filter 1A.
With a setting of OFF, modulation will not be applied.
Intensity [–99…+99]
Alternate Modulation can modify the cutoff frequency over a range nearly equivalent to the range
of human hearing.
If AMS is set to EG or LFO, the pitch can be modified to a maximum of ±8 octaves. (The LFO can
add an additional ±8 octaves of adjustment to the offset.)
If AMS is set to a controller, positive (+) settings of this parameter will raise the cutoff frequency,
and negative (–) settings will lower the cutoff frequency. The range of this change is a maximum of
10 octaves.
If AMS is set to SW1 or SW2, the cutoff frequency can be modified up to 10 octaves.
If AMS is set to Tempo, an Intensity setting of +10 will raise the cutoff frequency 1 octave when
the tempo doubles in speed.
For details on how Alternate Modulation and the other AMS functions operate, refer to page 157
“8. Appendix” in this manual and to page 33 “About alternate modulation” in the Basic Guide.
3–2b: Filter 1B Modulation
These parameters will be displayed if “1–1c: Oscillator mode” is set to double, and “3–1a: Rout-
ing” is set to parallel or serial.
These settings specify how Keyboard Tracking, Joy Stick (X), Aftertouch, and Alternate Modula-
tion will affect the cutoff frequency of filter 1B.
For details refer to “3–2a: Filter 1A Modulation.”
3–2c: Filter 1 EG
These settings specify the depth of the effect produced by the filter 1 EG (make settings in “4–1:
Filter 1 EG”) that creates time-variant changes in the cutoff frequency of filter 1A and 1B.
