"...The most exotic feature of Compressor II is the sidechain EQ. The “sidechain” is the part of the signal
that is used to control the compressor. Normally the sidechain signal is the same as the input signal.
However, it can make sense to apply some filtering here. Imagine a bass drum, a snare and some
chords in the background. The bass drum has a pretty high level and it will normally determine how
the compressor reacts. If you now turn the side chain EQ on and set its Frequency to 100 Hz and the
Gain to -15 dB, the bass drum will not influence the compression anymore and the behavior of the
compressor will be very different. You could also set the Frequency to around 1 kHz and turn up the
gain to make the compressor more responsive to the snare. Since the EQ is only in the sidechain and
not part of the normal signal path, it will not change the sound of the input signal. It only changes
how the compressor reacts to different frequencies of the input...."

Not much of a Live geek but I guess U need 2 group the kick and the sound U want 2 sidechain and the use Comp II on that track (or bouce u audio all of them 2gether)... or just use comp 2 on the master efx!
