Compressor (Comp); Equalizer (Eq) - Roland TD-12 Owner's Manual

Compressor (COMP)

A compressor adjusts the envelope (changes in the volume
over time) and changes the character of the sound in response
to playing dynamics.

Description
EMPHASIS
Emphasizes the at-
tack of the sound.
CRUSH
Press the attack.
This changes Thre
and Ratio values.
This changes Atck,
Hold, and Rels val-
ues.
Output level of the
compressor
Description
Volume level at
which compression
begins
Compression ratio
Time from when the
volume goes up the
threshold level until
the compressor effect
applies
Time compression is
kept
Time from when the
volume falls below
the threshold level
until the compressor
effect no longer ap-
plies
About Threshold and Ratio
As shown in the diagram below, these parameters determine
how the volume is to be compressed.

Threshold

Equalizer (EQ)

You can use three-band equalizers (for high, middle, and low
frequency ranges) to adjust the sound.

Parameter Value
Q 0.5–8.0
(only for MID)
Freq 20–1k (LOW),
(Frequency) 20–8k (MID),
1k–8k (HIGH)
Gain -15– +15 (dB)
