22 settings - negative gating
An interesting variant of the groove ducking
technique is negative gating which is based on
faster release times and the use of the Anti Log
mode. Higher ratios are also very typical for this
process.
If you feed a bass drum into the external side-
chain as a trigger signal, for example, the com-
pressor will reduce the audio signal by a signifi-
cant amount, resulting in gain reduction values
of 30 and 40 dB caused by the negative ratio.
After the trigger signal has gone, the gain re-
duction value is kept constant by the Anti Log
function for a short moment, after which it
snaps back very fast.
This special envelope makes the effect almost
sound like a gate – but with the difference that
the signal is made quieter instead of being to-
tally muted.
If you want the effect to be as stable as possible,
please take care that the trigger signals have
constant attacks and levels.
Of course you would not want to use extreme
effects like this for a standard compression sce-
nario, but if you are looking for some extraor-
dinary rhythmical effects, the negative gating
procedure might just be what you have been
looking for.
