3–3: Filter1 LFO Mod.
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) [–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. 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.
LFO modulation of Filter Cutoff
Intensity to B (LFO1) [–99…+99]
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) [–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.
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 canceled
out.
JS–Y Intensity to B (LFO1) [–99…+99]
This lets you use JS-Y to scale the amount of the LFO
applied to Filter B.
AMS (LFO1) [List of AMS Sources]
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 “Alternate Modulation Source
(AMS) List” on page 901.
Intensity to A [–99…+99]
This controls the depth and direction of the LFO1 AMS
modulation for Filter A.
For example, if AMS is set to After Touch , positive settings
mean that aftertouch will increase the amount of LFO1
applied to Filter A.
Intensity to B [–99…+99]
This controls the depth and direction of the LFO1 AMS
modulation for Filter B.
