ROM-27 VCF+DISTORT

VCF+DISTORT combines a voltage control filter and a raspy distortion. Three effects can be

obtained: Distortion, Wah-wah, and Auto-wah. The last two functions use the same VCF. These

filters can be disabled or used as EQ if desired. There is a second VCF that exists after the

distortion. It can be set to act like a simple speaker simulator, or it can be modulated in parallel

with the pre-distortion VCF.

The BUS1, BUS2, and BUS3 MIX parameters can be routed into the effect with different Dry/Wet

mixes.

The parameters available for this algorithm are:

DIST LEVEL IN Range: 0 to 99

This parameter controls the gain going into the distortion effect. DIST LEVEL IN will boost the

signal level up to 48 dB. For more distortion, use a high input level gain and turn the DIST

LEVEL OUT down to keep the volume under control. For less distortion, use a low gain input

level and a higher output volume.

DIST LEVEL OUT Range: 0 to 99

This parameter controls the gain coming out of the distortion effect. Generally, if the DIST

LEVEL IN is set high, set this parameter lower to control the volume.

PRE-DIST VCF FC Range: 1 to 99

This parameter determines the filter cut off frequency before the distortion. Higher values have a

brighter sound. This parameter can be modulated, using a CV Pedal for a wah-wah pedal effect.

To disable the distortion filter, set this parameter to 99. To use as an EQ, set the desired value

and make sure PRE-DIST ENV FOL is +0. To use as the auto-wah, set this parameter close to 1

(lower values) and turn on PRE-DIST ENV FOL.

PRE-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 PRE-DIST VCF FC parameter determines where (at what frequency) this peak will

occur, the PRE-DIST VCF Q setting controls the presence of the peak. This setting is important for

the auto-wah effect.

PRE-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, the PRE-DIST VCF FC will go high, but then come down to its nominal setting.

When set to negative mid values, the PRE-DIST VCF 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.
