Knob 4
• Use this knob to set the filter's output level.
• Note that high settings may produce distortion when used with certain sample sounds
or when many samples are played together.
Q/Width
Knob 5
This knob sets the Q value (resonance) or width setting, depending on the filter type.
• If you select a low-pass or high-pass filter, this setting selects the Q value. The Q value
determines the amount of emphasis applied to frequencies that are very close the
cutoff point. (See drawing above.) Higher settings produce stronger emphasis. Note
that high settings for a LowPass2 or HiPass2 filter may produce distortion with cer-
tain samples.
• If you select the band-pass filter, this setting determines the width of the band that is
allowed to pass. Increasing the setting will widen the band, allowing more frequen-
cies to pass.
• If you select the band-eliminate filter, this setting determines the width of the fre-
quency ranges that are allowed to pass. Increasing the setting will allow more fre-
quencies to pass (will reduce the elimination zone). Note that the elimination band
itself becomes narrower as you increase the value.
Low-pass filter #2. Offers much higher Q (resonance) than low-
pass filter #1.
High-pass filter #1. (A high-pass filter blocks out all frequen-
cies below the cutoff frequency.)
High-pass filter #2. Offers much higher Q (resonance) than high-
pass filter #1.
Band-pass filter. (Allows only frequencies near the cutoff fre-
quency to pass; blocks out all higher and lower frequencies.)
Band-eliminate filter. (Blocks out the frequency range around
the cutoff frequency, while allowing higher and lower frequen-
cies to pass.)
