elysia mpressor Dual-Channel Creative Compressor - Manual (Page 7)

7 controls - sidechain
If the SC Extern button is active, compression
will not be controlled by the actual input signals
anymore, but by different audio signals which
are fed into a specially assigned buss.
Note: Your host software must support this
functionality! If no buss is assigned to the side-
chain of the mpressor plug-in, activating the
SC Extern button will not produce the desired
results.
If a duplicate of the input signal is processed
with an equalizer and then fed into the side-
chain input, for example, the result will be
frequency dependent compression. Another
example is to send the bass drum of a drum
sequencer into the sidechain input in order to
achieve nice groovy compression that is pump-
ing in time with the music.
The external sidechain is coupled with a fixed
high pass filter that has its cut-off frequency at
80 Hz with a slew rate of 6 dB per octave.
This reduces the influence of the low frequen-
cies in the sidechain on overall compression by
a certain amount in order to keep the effect as
balanced as possible.
