Electrix Filter Queen - Manual (Page 8)

ENV Following Explained: The ENV Follower tracks the
amplitude (volume) of the input to Filter Queen and opens up
the Filter Frequency in scale with the dynamics. ENV Following
will produce totally funked out sounds when the filter frequency
control is set low and the ENV depth is set just right to track the
dynamics of the music.
ENV Follower Depth: Sets the amount the input signal’s
'dynamic envelope' will affect the Filter frequency. Start around 5
with this control. 3-7 is the general range in which most instru-
ments trigger the envelope follower properly. 7-10 is for low-
level signals.
ENV Follower Release: Turning the release knob slows
down and smoothes out the ENV follower response. Use short-
er release settings for more immediate response. This control
can subtly change the percussive quality of your mix.
ENV Follower Band Select: Selects between 7 combina-
tions of the frequency bands the ENV follower can track. The
ENV follower band select can be used to focus the ENV
Follower in on a particular frequency band. For example the mid
band will focus in on the snare drum and vocals, while the high
band will pick up hihats and cymbals. The combinations are rep-
resented by 3 LED for High, Mid, and Low. The combinations
are: All bands, High, Mid, Low, Low+High, Low+Mid,
High+Mid. Note: Every time the Band button is pressed Filter
Queen will cycle to the next combination. However, at any point
in the cycle the Band button can be held down for 300ms and it
will return directly to All bands.
Filter Frequency: Sets the cutoff frequency of the stereo fil-
ter. Use it in conjunction with the resonance control. The more
resonance you use the more distinct any changes you make with
frequency will be. The frequency tuning range of the filter cov-
ers a 12 octave range from 10 Hz to 20 kHz. Any 3rd party 1/4"
TRS Expression Pedal, (such as a Roland EV-5) can control the fil-
ter frequency. (Great for guitar or bass.)
Resonance: This controls the level of the peak at the reso-
nant frequency of the filter, i.e. the frequency you dialed in with
the frequency knob. The Filter Queen’s resonance control can be
set to negative values by rotating the control all the way counter
clockwise. In Low Pass, High Pass and Band Pass modes, nega-
tive resonance will simply smooth out the response of the filter,
making it less distinct. In Notch Filter mode, negative feedback
will increase the depth of the notch filter making it more pro-
nounced.
