Filter Type, Filter A, Filter B
Selects the type of filter, and specify the “Frequency” 
(cutoff frequency) and “Resonance” (resonance level).

• Low Pass Resonance (24 dB/oct low pass filter 

with resonance): Make settings for filter A.

• Low Pass & High Pass (12 dB/oct low pass filter 

and 12 dB/oct high pass filter in series connection): 
Make low pass filter settings in filter A, and high 
pass filter settings in filter B.

This is the most common type of filter, which passes 
the low frequency range and cuts the high frequency 
range. When the overtones of the high range are cut, a 
bright sound will become darker (more mellow).
24 dB/oct and 12 dB/oct refer to the steepness of the 
cut. 24 dB/oct means that the gain will decrease 24 dB 
in one octave (i.e., as the frequency doubles). A 12 dB/
oct filter would decrease the gain 12 dB in one octave. 
The 24 dB/oct filter produces a steeper cut.

This type of filter passes the high frequency range and 
cuts the low frequency range. Use this when you wish 
to make the sound thinner. However if the cutoff fre-
quency (Frequency) is raised excessively high, the vol-
ume will become very low.

When “Resonance” is set to a higher value, the over-
tones in the region of the cutoff frequency will be 
boosted as shown in the diagram below, giving a dis-
tinctive character to the sound.

Controllers and the filter EG can be used to modulate 
the filter cutoff frequency that was specified in the 
Basic page. By using a controller to vary the tone or by 
using an EG to create time-varying changes, you can 
add a rich variety of tonal change to the sound.

This varies the cutoff frequency according to the posi-
tion of the key on the keyboard that you play.

• When Ramp “Low” is set to a positive (+) value, 

the cutoff frequency will rise as you play lower on 
the keyboard, making the sound brighter. When set 
to a negative (–) value, the cutoff frequency will fall 
as you play lower on the keyboard, making the 
sound darker.

• When Ramp “High” is set to a positive (+) value, 

the cutoff frequency will rise as you play higher on 
the keyboard, making the sound brighter. When set 
to a negative (–) value, the cutoff frequency will fall 
as you play higher on the keyboard, making the 
sound darker.

• Int. “to A” and “to B” adjust the effect that 

keyboard tracking will have on filters A and B 
(

Adjusts the effect produced by the filter EG, whose set-
tings are made in the EG page.

• Use the Int. “to A” and “to B” settings to specify 

the depth of the filter EG.

• Use the Vel “to A” and “to B” settings to specify 

the effect of velocity on the filter EG.

• “AMS” and “Int to A, B” adjust the effect that AMS 

will have on the filter EG depth.

These three settings will determine the depth of the 
tonal change produced by the filter EG.

Set this when you wish to produce tonal change by 
using controllers etc. to vary the cutoff frequency.

Indicates settings that allow the LFO to produce cyclic 
changes in tone (a “wah” effect).
