3–3: Filter1 LFO Modulation
3–3a
3–3b
LFO1, LFO2, and the Common LFO can all modulate
Filter A and B's cutoff frequencies. You can control the
strength of each LFO's modulation in three different
ways, independently for each filter:
• Set an initial amount of LFO modulation, using the
Intensity to A and B parameters.
• Use JS-Y to scale the amount of the LFO.
• Use any AMS source to scale the amount the LFO.
You can use each of these methods for each of the three
LFOs, and do so separately for both Filter A and Filter
B. The results are added together to produce the total
LFO effect.
3–3a: LFO 1/2
LFO1
Intensity to A (LFO1)
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.
You can produce interesting effects by using the same
LFO to modulate two different parameters (such as
Filter A and Filter B), but with one set to a positive
intensity, and the other set to a negative intensity.

Intensity to B (LFO1)
This controls the initial effect of the LFO on Filter B's
cutoff frequency, before any JS-Y or AMS modulation.
JS–Y Intensity to A (LFO1)
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.
Negative (–) settings will invert the phase of the LFO.
You can also use this to reduce the initial amount of the
LFO, as set by Intensity to A, above. For example:
1. Set Intensity to A to +50.
The LFO will now have a fairly strong effect on the
filter cutoff.
2. Set JS-Y Intensity to A to –50.
Now, if you move the joystick down, the effect of the
LFO will fade away. When the joystick is all the way at
the bottom of its range, the LFO will be completely
cancelled out.
JS–Y Intensity to B (LFO1)
This lets you use JS-Y to scale the amount of the LFO
applied to Filter B.
AMS (LFO1)
This selects any AMS modulation source to scale the
amount of the LFO applied to Filters A and B. The two
filters share a single AMS source, but with separate
intensity settings.
For a list of AMS sources, see "AMS (Alternate
Modulation Source) List" on page 967.
