Edit/Effect Parameters
POST-DIST VCF FC
Range:
01 to 99
This parameter determines the filter cut off frequency after the distortion. Higher values have a
brighter sound. This parameter can also be modulated, using a CV Pedal for a wah-wah pedal
effect. To disable the post-distortion filter, set this parameter to 99.
POST-DIST VCF Q
Range:
1 to 25
This parameter determines the level and width of the resonant peak at the filter cutoff point.
While the FC (filter cutoff) parameter determines where (at what frequency) this peak will occur,
the Q setting controls the presence of the peak. This setting is important for the auto-wah effect.
POST-DIST ENV FOL
Range:
-99 to +99
This parameter determines how much the amplitude of the incoming signal will modify the
distortion filter cutoff frequency. When set to +0, no modification will occur. When set to mid
positive values, FC will go high, but then come down to its nominal setting. When set to negative
mid values, FC will go low, and then go back up to its nominal setting How quickly it does so is
determined by the ATTACK and RELEASE parameters. This sound is the auto-wah; positive
values will boost the high frequencies, offering an “oww-oww” sound, and negative values will
cut the high frequencies, producing a “dweep-dweep” sound.
ATTACK
Range:
50µs to 10.0s
This parameter sets the attack of the envelope follower (i.e. determines how closely the attack is
followed) once the incoming signal has been detected. Generally the attack should be short.
RELEASE
Range:
1ms to 10.0s
This parameter sets the amount of time after the incoming signal has ceased for the envelope
follower to shut down. Generally these times are longer than the attack times.
DISTORTION BYPASS
Range:
OFF or ON
This parameter allows you to bypass the distortion (as shown on the signal routing diagram).
PRE-EQ HP FC
Range:
0 to 1000 Hz
This parameter filters out the low frequencies before the EQ. The higher the value, the less low
frequencies will pass through.
MOD SRC 1
MOD SRC 2
DST 1
DST 2
MIN 1
MIN 2
MAX 1
MAX 2
These parameters are explained in detail in Section 5 — Effect Concepts.
ROM-28 GUITAR AMP 1
ROM-29 GUITAR AMP 2
These algorithms recreate the warm sound of a guitar amplifier. They do this by emulating tube
distortion characteristics. These algorithms are good for all stringed instruments. GUITAR AMP
1, designed for Hard Rock, offers more distortion than GUITAR AMP 2, which is optimized for
“bluesy” type sounds. The BUS1 and BUS2 MIX parameters can be routed into the effect with
different Dry/Wet mixes.
