Bandpass This bandpass filter passes only a relatively narrow band of frequencies centered at the cut-
off point.
• Knob 4 (Q/Width) adjusts the width of the filter's pass band.
• Knob 5 (Distance) has no effect with this filter type.
BandElim The opposite of the bandpass response, the Band Elimination filter "eliminates" (cuts out) a
relatively narrow band of frequencies centered at the cutoff point.
• Knob 4 (Q/Width) adjusts the width of the filter's elimination band.
• Knob 5 (Distance) has no effect with this filter type.
Peak1 A peaking filter which can be used to boost a band of frequencies centered at the cutoff
point.
• Knob 4 (Q/Width) adjusts the gain of a resonant peak at the cutoff frequency.
• Knob 5 (Distance) has no effect with this filter type.
Peak2 The "Peak2" filter mixes the direct signal with the peak-filtered signal for a drier sound.
• Knob 4 (Q/Width) adjusts the gain of a resonant peak at the cutoff frequency.
• Knob 5 (Distance) has no effect with this filter type.
2Peaks This mode provides two peaks.
• Knob 4 (Q/Width) adjusts the gain of resonant peaks at the cutoff frequencies of both
peaks.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two peaks.
2Dips This mode provides 2 dips.
• Knob 4 (Q/Width) simultaneously adjusts the width of both filter dips.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two dips.
DualLPFs Two low-pass filters having different cutoff are combined to produce a "stepped" low-pass
response.
• Knob 4 (Q/Width) adjusts the gain of resonant peaks at the cutoff frequencies of both low-
pass filters.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two low-
pass filters.
LPF+Peak A combined low-pass filter and peaking filter.
• Knob 4 (Q/Width) adjusts the gain of resonant peaks at the cutoff frequencies of both fil-
ters.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two filters.
DualHPFs Two high-pass filters having different cutoff are combined to produce a "stepped" high-pass
response.
• Knob 4 (Q/Width) adjusts the gain of resonant peaks at the cutoff frequencies of both high-
pass filters.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two high-
pass filters.
HPF+Peak A combined high-pass filter and peaking filter.
• Knob 4 (Q/Width) adjusts the gain of resonant peaks at the cutoff frequencies of both fil-
ters.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two filters.
LPF+HPF A combined low-pass and high-pass filter.
• Knob 4 (Q/Width) adjusts the gain of resonant peaks at the cutoff frequencies of both fil-
ters.
• Knob 5 (Distance) adjusts the "distance" between the cutoff frequencies of the two filters.
The graphic response display in the upper right corner of the LCD panel will give you an idea of the
type of response you have created. You can also use the [AUDITION] key at any time to actually hear
the sound produced with the current settings.
