Effects
Compressors, Expanders, and Gates
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 set the bandwidth of the filter 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 filters, 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 filter frequencies for each set of filters. After setting the filter parameters
(Freq, Gain, and Width), the FreqScale parameters will move each of the four filter 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 filters, and when set to
100%, the "B" parameters control the filters. Between 0 and 100%, the filters are at interpolated
positions. When morphing from A to B settings, the A filter #1 will change to the B filter #1, A
filter #2 moves to B filter #2, and so on. Range is 0 to 100%.
Compressors, Expanders, and Gates
A wide range of Compression and Expansion effects is available in the PC3K. The various
algorithms include different combinations of:
•
compressors with soft‐knee characteristic—the compression action comes in gradually as
the signal level approaches the threshold
•
compressors with hard‐knee characteristic—the compression action comes in abruptly
when the signal reaches the threshold
•
expanders
•
multiband compressors that break the signal up into three frequency bands and compress
them all separately
•
sidechains or output EQs
•
reverbs and compressors in combination
•
gates
•
gated reverbs
All of the Compression algorithms use these parameters:
FdbkComprs (Feedback Compression) selects whether to use feed‐forward (set this to "Out") or
feed‐back (set this to "In") compression. The feed‐forward configuration uses the input signal as
a side‐chain source, which is useful when the compressor has to act really quickly. The feed‐back
configuration uses the compressor output as the side‐chain source, which lends itself to more
subtle, but not as quick‐reacting, compression.
Atk (Attack) Time for the compressor is adjustable from 0.0 to 228.0 ms.
Rel (Release) Time for the compressor is adjustable from 0 to 3000 ms.
