The Q control affects the width of the already narrow notch lter. Higher Qs give you an even
more narrow notch.
Comb (Resonate) Filter
The Slope control acts as a dry/wet control for this Filter, which is really more of a delay than a
lter anyway!
The Tune control is as with the other Filter types.
The Q controls resonance, with positive values giving you all harmonics and negative values
given you odd harmonics.
Data Display: Shows Slope/Tune/Q depending on which control is moved. The Tune control
will show MIDI note or Frequency depending on back panel setting, allowing you to tune the
lter based on MIDI note and frequency simultaneously.
Slope: Unique continuously variable slope control from 0 - 48 dB/Oct. Allows you to modulate
slope control and ne tune the lter slopes without having to jump between settings.
“Slope Control” Notes:
The Slope control is a multifunction control, affecting slope on the Low Pass, Band Pass, and
High Pass lters and affecting notch “depth” on the Band Reject lter and “blend” on the Comb
Filter.
For all Filter Types the bottom position represents“no effect”. For slopes, this is a slope of “zero”
(no effect). For the Band Reject and Comb lter the bottom position equals 100% “dry” (no
effect). This is for consistency, especially as it concerns linking the Filters with the EQs in the
Master section, where moving the master Gain control to 0% effectively removes any
processing on ALL bands, lter and EQ alike.!
Tune: Tune the lter in semitones from 20 Hz to 20 kHz, allowing you to quickly dial in the
lter based on pitch rather than frequency. Frequency is also displayed on the Data Display if
selected on the back panel, which is the default (the display can be switched to show MIDI
note).
Q: Features positive and negative resonance amounts. Negative resonance creates even more
gentle slopes around the cutofffrequency.
Routing:
The Routing selector allows the lters to be moved between three positions: “Pre EQ” ,“Post
EQ”, and“Post Saturation”. When in the default “Pre EQ” position, the lter can remove
“garbage” (such as sub sonic energy) to prevent it from being saturated in the EQ bands that
follow. Moving it to the “Post EQ” position prevents it from affecting saturation in any way, but
still affects the main EQ path/signal.“Post Saturation” allows you to lter the saturated signal
before it is summed with the EQ signal. Applications include removing excess high-frequency
by using a low pass lter, or creative effects such as band pass or comb ltering of the
saturation signal.
EQ Bands 1-5
Selig ColoringEQ features ve identical EQ bands, with ten EQ types to choose from each
covering the entire audible spectrum. Beyond the typical EQ types, the Selig ColoringEQ also
includes unique “constant slope” shelves, Tilt/Shift and Smily/Frowny“tone controls”, and
