The Gate Module
The Gate is part of the DrawmerGCL plug-in. It 
is based on the highly acclaimed Drawmer 
DS201 hardware dynamics processor, which was 
instrumental in creating many recording effects 
that have become industry standard practice 
such as the Gated reverb, and enhanced percus-
sive kick-drums.

Gate Parameters
HF & LF Key Filters
These controls adjust the roll-off frequencies of 
the Key filters. The LF or low frequency filter 
ranges from 32 Hz to 4 kHz and attenuates sig-
nals below the cut-off frequency at 12 dBs per 
octave. The HF or high frequency filter ranges 
from 250 Hz to 16 kHz and attenuates signals 
above the cut-off frequency. When both filters 
are used, only the frequency band between the 
two settings remains. 
These controls do not overlap each other, since 
this would produce very little audio output.
Side-Chain/Internal Control
Setting this control to Side-Chain enables side-
chain processing. Side-Chain processing permits 
triggering of the Gate by a mono source or key 
input other than the gated material itself. Setting 
this control to internal disables side-chain pro-
cessing. (See “Using the Side-Chain Input in 
DrawmerGCL” on page 24 for more informa-
tion.) 
Key Listen/Normal Switch
Set this toggle to Key Listen to monitor the au-
dio specified as the key input. (See “Using the 
Side-Chain Input in DrawmerGCL” on page 24 
for more information.)
Threshold Control
The Threshold control sets the level below 
which gating takes place (the level at which the 
output of the Key Filter triggers the Gate). 
Threshold ranges from –70 dB to 0 dB. Setting 
this control fully counter-clockwise closes the 
Gate.
