Set the cutoff, resonance, and input and output levels of

This lets you bypass Filter A completely.
If Bypass is Off, Filter A functions normally.
When Bypass is On, Filter A will have no effect.
This controls the cutoff frequency of Filter A, in increments
of 1/10 of an octave. The specific effect of the cutoff fre‐
quency will change depending on the selected "Filter Type."
This adjusts the volume level at the input to the filter. If you
notice that the sound is distorting, especially with high Res‐
onance settings, you can turn the level down here, or at the
Resonance emphasizes the frequencies that are around the
When this is set to 0, there is no emphasis, and frequencies
beyond the cutoff will simply diminish smoothly.
At medium settings, the resonance will alter the timbre of
the filter, making it sound more nasal, or more extreme.
At very high settings, the resonance can be heard as a sepa‐
rate, whistling pitch.
To make the resonance track the keyboard pitch, please see
"Key Follow" on page 39.
AMS Source (Resonance)
This selects an AMS source to control the Resonance
amount. For a list of AMS sources, please see "AMS (Alter‐
nate Modulation Source) List" on page 121.
This controls the depth and direction of the Resonance mod‐
For example, if Velocity has been selected, changes in key‐
board velocity will affect the resonance. With positive (+)
values, the resonance will increase as you play more
strongly, and as you play more softly the resonance will
approach the level specified by the Resonance setting. With
negative (–) values, the resonance will decrease as you play
more strongly, and as you play more softly the resonance
will approach the level specified by the Resonance setting.
The resonance level is determined by adding the Resonance
and" AMS Intensity" values.

This controls the output level of Filter A. You can use this to
balance the volumes of Filters A and B when the Routing is
set to Parallel, or to turn down the volume to avoid clipping
later in the signal chain.
This selects a modulation source to control the output level
of Filter A. For a list of AMS sources, please see "Alternate
Modulation Source (AMS)" on page 121.
This controls the depth and direction of the output level
Filter B is available if the "Routing" is Serial or Parallel. Oth‐
erwise, all parameters in this section are unavailable, and
cannot be edited.
The filter B parameters are the same as for filter A ( "Filter
A" on page 36).
