Filter Types and 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, see “Key
Follow,” on page 73 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 Filter EG tab; the
way that it affects the filters is controlled by the parameters
described below, on the Filter Mod tab:
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 scale the amount of EG modulation.
The AMS setting selects a 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 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 Filter LFO Mod tab lets you set up the following
parameters separately for each LFO:
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 a 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.
