5-4: Filter LFO Mod

There are three LFO-to-Frequency controls for each
filter: a basic amount (LFO Intensity), joystick -Y
control of LFO amount (JS- Y Intensity), and AMS
control of LFO amount (AMS Intensity). The three
controls are summed together to determine the final
LFO amount.

5-4a: Filter A

LFO Select

[LFO 1, LFO 2, LFO 3, LFO 4,

Common LFO]

This selects an LFO to modulate Filter A’s cutoff
frequency.

The LFO Intensity, JS -Y Intensity, and AMS are all
summed together to produce the final amount of LFO
pitch modulation.

LFO Intensity

[–99…+99]

This controls the initial effect of the LFO on Filter A’s
cutoff frequency, before any JS+Y or AMS modulation.

Negative (–) settings will invert the phase of the LFO.

JS -Y Intensity

[–99…+99]

Moving the joystick “down” from the center detent
position, towards yourself, produces the JS -Y
controller. You can use this to scale the amount of the
LFO applied to Filter A.

This parameter sets the maximum amount of LFO
modulation added by JS -Y.

AMS

[AMS Sources]

This selects an AMS modulation source to scale the
amount of the LFO applied to Filter A’s cutoff
frequency.

For a list of AMS sources, see “AMS (Alternate
Modulation Source) List” on page 967.

Intensity

[–99…+99]

This controls the depth and direction of the LFO AMS
modulation.

5-4b: Filter B

The settings for Filter B are the same as those for “5-4a:
Filter A,” above.

When Link is On, or when the Filter Routing is set to
Single or 24dB/oct, all of these parameters are grayed
out.
