Vcf - Distort 2 - ENSONIQ DP/4+ Reference Manual

VCF - DISTORT 2

VCF - Distort 2 combines a voltage control filter and a raspy distortion, and a second voltage
control filter. This algorithm is identical to the VCF - Distort 1 algorithm, with the addition of a
"tunable" feedback signal.

01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters earlier in this section. For this
algorithm, Volume controls the distortion output level. For high distortion input gains, use lower
volumes.
03 — Distortion Level In
Controls the gain going into the distortion effect. Distortion Level In will boost the signal level
up to 48 dB. For more distortion, use a high input level gain and turn the Distortion Level Out
(04) down to keep the volume under control. For less distortion, use a low gain input level and a
higher output volume.
04 — Distortion Level Out
Controls the gain coming out of the distortion effect. Generally, if the Distortion Level In (03) is
set high, set this parameter lower to control the volume.
05 — Pre-Distortion VCF Fc
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 envelope follower (parameter 07) is 00. To use as the auto-wah, set this parameter
close to 01 (lower values) and turn on parameter 07.
06 — Pre-Distortion VCF Q
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
Determines how much the amplitude of the incoming signal will modify the distortion filter
cutoff frequency. When set to +00, no modification will occur. When set to mid positive values,
the Pre-Distortion VCF Fc will go high, but then come down to its nominal setting. When set to
negative mid values, the Pre-Distortion VCF 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-oww" sound, and
negative values will cut the high frequencies, producing a "dweep-dweep" sound.
