Filter Types and Cutoff Frequency
Low Pass

Band Reject
Cutoff Frequency
Resonance
Resonance emphasizes the frequencies around the
cutoff frequency, as shown in the diagram below.
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 separate, whistling pitch.
To make the resonance track the keyboard pitch, please
see "Key Follow," on page 33 of the Parameter Guide.

Modulating the filters
You can modulate the filter cutoff frequency using the
Filter EG, the LFOs, keyboard tracking, and other
built-in and MIDI controllers. This is a great way to
add a rich variety of tonal change to the sound.
Filter EG
The Filter EG is a multi-stage envelope, which you can
use to modulate the filter (naturally!) as well as other
Program parameters. The EG itself is set up on the EG
tab; the way that it affects the filters is controlled by the
Detailed Editing with Programs Using Filters
parameters described below, on the Filter1/2–
Modulation page:
The Intensity to A and Intensity to B settings control
the basic amount of EG modulation for filter
frequencies A and B, respectively, before other
modulation.
The Velocity to A and Velocity to B settings let you use
velocity to control the amount of EG modulation.
The AMS setting selects an AMS modulation source to
scale the amount of the Filter EG applied to Filters A
and B. The two filters share a single AMS source, with
separate intensity Into A or to B settings.
LFO modulation
You can modulate the filter via LFO1, LFO2, and the
Common LFO. Among other applications, LFO
modulation of the filter can produce the classic "auto-
wah" effect.
The Filter1/2– LFO Mod. page lets you set up the
following parameters separately for each LFO:
High resonance
Intensity to A and Intensity to B specify how much
the LFO changes the tone.
JS-Y Intensity to A and JS-Y Intensity to B specify the
depth of the wah effect produced by the LFO when the
joystick is moved toward yourself, or when CC#2 is
received.
The AMS setting selects an AMS modulation source to
scale the amount of the LFO applied to Filters A and B.
The two filters share a single AMS source, with
separate intensity settings.
For example if AMS is set to SW1: CC#80, turning SW1
on will apply an auto-wah effect.
