Velocity to A

This parameter specifies the depth and direction of the effect that velocity will have on the time-varying changes created by the filter EG (as set on “Page 11 - Filter EG”) to control the filter A cutoff frequency.

With positive (+) values, playing more strongly will cause the filter EG to produce greater changes in cutoff frequency. With negative (–) values, playing more strongly will also cause the filter EG to produce greater changes in cutoff frequency, but with the polarity of the EG inverted.

99…+99 Value of the Velocity to A parameter.

Velocity to B

This parameter specifies the depth and direction of the effect that velocity will have on the time-varying changes created by the filter EG to control the filter B cutoff frequency (see “Velocity to A”).

99…+99 Value of the Velocity to B parameter.

EG Intensity to A

Specifies the depth and direction of the effect that the time- varying changes created by the filter 1 EG will have on the fil- ter A cutoff frequency.

With positive (+) settings, the sound will become brighter when the EG levels set by Filter EG “Level” and “Time” parameters are in the “+” area, and darker when they are in the “–” area.

With negative (–) settings, the sound will become darker when the EG levels set by Filter EG “Level” and “Time” parameters are in the “+” area, and brighter when they are in the “–” area.

-99…+99 Parameter value.

EG Intensity to B

Specifies the depth and direction of the effect that the time- varying changes created by the filter EG will have on the filter B cutoff frequency (see “EG Intensity to A”).

-99…+99 Parameter value.

EG AMS (Alternate Modulation Source)

Selects the source that will control the depth and direction of the effect that the time-varying changes produced by the fil- ter EG will have on the cutoff frequency of filters A and B. See “AMS (Alternate Modulation Source) list” on page 123.

Intensity to A

Specifies the depth and direction of the effect that “AMS” will have on filter A. For details on how this will apply, refer to “EG Intensity to A”.

Intensity to B

Specifies the depth and direction of the effect that “AMS” will have on filter B. For details on how this will apply, refer to “EG Intensity to A”.

Note: The sum of the settings for “Velocity to A/B”, “Intensity to A/B”, and “(AMS) Intensity to A/B” will determine the depth and direction of the effect produced by the filter EG.

Filter A/B modulation

AMS1(fA/B) (Alternate Modulation Source1 for filter A/B)

Selects the source that will control modulation of the filter A cutoff frequency. See “AMS (Alternate Modulation Source) list” on page 123.

Note: The filter B parameters will be displayed when “Filter Type” on page 112 is Low Pass & High Pass.

Intensity

Specifies the depth and direction of the effect that “AMS1” will have.

When “AMS1” is JS X, a positive (+) value for this parameter will cause the cutoff frequency to rise when the joystick is moved toward the right, and fall when the joystick is moved toward the left. With a negative (–) value for this parameter, the opposite will occur.

This value is added to the setting of the Filter A “Frequency”.

AMS2 (Alternate Modulation Source2)

Selects the source that will control modulation of the filter A cutoff frequency (see “AMS (Alternate Modulation Source) list” on page 123).

Intensity

Specifies the depth and direction of the effect that the selected source will have (see “Intensity” on page 114).

PAGE 9 - FILTER LFO1

Here you can use the filter LFO to apply cyclic modulation to the cutoff frequency of the filter (for the selected oscillator) to create cyclical changes in tone.

Filter LFO1Osc1

Selected: Osc1

Intensity to A: +0

Intensity to B: +0

Joystick -Y to A: +5

Selected

Use this parameter to select an oscillator to put in edit. Alter- natively, you can select oscillators using the F1-F4 buttons.

Intensity to A

Specifies the depth and direction of the modulation that LFO1 (set on “Page 17 - LFO1”) will have on the cutoff fre- quency of filter A. Negative (–) settings will invert the phase. -99…+99 Parameter value.
