Treb Gain and Bass Gain control the amount of cut or boost above (Treb) or below (Bass) the
center frequency. The range is -79 to +24 dB.
Midn Gain sets the cut or boost for the parametric band n, with a range of -79 to +24 dB.
Midn Freq sets the center frequency for parametric band n, with a range of 16 to 25088 Hz, in
increments of a semitone.
Midn Width sets the bandwidth of the Þlter on band n, with a range of 0.01 to 5 octaves.
Enhancers
Enhancers modify the spectral content of the input signal by boosting existing spectral content,
or stimulating new ones. Two- and three-band versions are provided.
Drive adjusts the input into each band. Increasing the drive will increase the effects. Range is
-79.0 to 24.0 dB.
Xfer adjusts the intensity of the transfer curves. Range is -100 to 100%.
EQ Morpher
This algorithm uses two four-band bandpass Þlters, A and B, and moves between them, which
among other things, can produce a very convincing simulation of a human vocal tract.
FreqScale offsets the Þlter frequencies for each set of Þlters. After setting the Þlter parameters
(Freq, Gain, and Width), the FreqScale parameters will move each of the four Þlter frequencies
together by the same relative pitch. Range is -8600 to 8600 cents.
Morph A>B. When set to 0% the A parameters are controlling the Þlters, and when set to 100%,
the B parameters control the Þlters. Between 0 and 100%, the Þlters are at interpolated positions.
When morphing from A to B settings, the A Þlter #1 will change to the B Þlter #1, A Þlter #2
moves to B Þlter #2, and so on. Range is 0 to 100%.
Compressors, Expanders, and Gates
A wide range of Compression and Expansion effects is available in KDFX. The various
algorithms include different combinations of:
¥
Compressor with either soft-knee or hard-knee characteristic
¥
Expander
¥
Multiband compressor that breaks the signal up into three frequency bands and compresses
them all separately
¥
Sidechain or output EQ
¥
Reverb and compressor in combination
¥
Gate
¥
Gated reverb
All of the compression algorithms use these parameters:
FdbkComprs (Feedback Compression) selects whether to use feed-forward (set this to Out) or
feedback (set this to In) compression. The feed-forward conÞguration uses the input signal as
the side-chain source. The feedback conÞguration uses the compressor output as the side-chain
