Modifying the Brightness of
the Sound (Filter)
Sound consists of a large number of overtones at vari-
ous frequencies. By using a filter, you can cause only a
specific range of overtones to be passed or attenuated,
thus modifying the brightness. The FILTER section lets
you make settings that affect the brightness of the
sound in this way.
Selecting the Type of Filter (Filter
Type)
Select the type of filter.
1. Make sure that the [FUNC] indicator is
dark.
2. Press [FILTER TYPE] several times to select
the type.

OFF:
The filter will not be used (all four indicators are dark).
LPF (Low Pass Filter):
This is the most common type of filter, and allows fre-
quencies below the cutoff frequency to pass. It is used
to make the sound more mellow.
BPF (Band Pass Filter):
This filter allows frequencies in the region of the cutoff
frequency to pass, and cuts the rest.
HPF (High Pass Filter):
This filter allows frequencies above the cutoff frequency
to pass. It is used to make the sound brighter and sharper.
PKG (Peaking Filter):
This filter boosts the overtones in the region of the cut-
off frequency. It will emphasize the mid-range, and is
useful for creating a distinctive sound.

By selecting the Peaking Filter as the Filter Type and
using the LFO to modulate the cutoff frequency, you
can create a ÒwahÓ effect.

Brightening the Sound (Cutoff
Frequency)
Specifies the frequency at which the filter will begin to
affect the frequency components of the waveform (the
Cutoff Frequency). By changing the cutoff frequency,
you can control the brightness of the sound.
1. Make sure that the [FUNC] indicator is
dark.
2. Rotate the [CUTOFF] knob to adjust the cut-
off frequency value.
fig.3-23
Range: 0Ð127
The effect will depend on the Filter Type.
LPF (Low Pass Filter)
Rotating the knob clockwise will cause the sound to
become brighter, approaching the original waveform.
Rotating it counterclockwise will cut more of the high
frequency overtones, making the sound darker.
* For some waveforms, you may not be able to hear any
sound if you lower the value too far.
