06 - Pre-Distortion VCF Q Range: 01 to 25
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.
07 - Envelope Follower to Pre VCF Range: - 99 to +99
Determines how much the amplitude of the incoming signal will modify the distortion filter
cutoff frequency. When set to
00, no modification will occur. At mid positive values, Fc will go
high,
but then come down to its nominal setting. At negative mid values, Fc will go low, and
then go back up to its nominal setting How quickly it does so is determined by parameters 11
and 12. This sound is the auto-wah; positive values will boost the high frequencies, offering an
"oww" sound, and negative values will cut the high frequencies, producing a "dweep" sound.
08 - Post-Distortion VCF Fc
09 - Post-Distortion VCF Q
10 - Envelope Follower to Post VCF
These three parameters are identical to the previous parameters, and are used to control the
second VCF that exists after the distortion.
11 - Envelope Follower Attack
Range: SOilS to 10. 0s
Sets the attack of the envelope follower (Le . determines how closely the attack is followed) once
the incoming signal has been detected. Generally the attack
should be short.
12 - Envelope Follower Release
Range: 1 ms to 10.05
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.
13 - Distortion Bypass Range: Off or On
This parameter allows you to bypass the distortion (as shown on the previous diagram) .
14 - Pre-EQ High Pass Cutoff Range: 0 to 1000 Hz
Filters out the low frequencies before the EQ. The higher the value, the less low frequencies will
pass through .
15 - Mod1 Source
16 - Mod1 Destination Parameter
17 - Mod1 Param Range Min
18 - Mod1 Param Range Max
19 - Mod2

20
- Mod2 Destination Parameter
