Chapter 4. Effect Settings
Chapter 4 [EFFECTS]
A compressor adjusts the envelope (changes in the volume
over time) and changes the character of the sound in response
to playing dynamics.
fig.04-003_70
For more detailed setting, adjust the parameters below.
About Threshold and Ratio
As shown in the diagram below, these parameters determine
how the volume is to be compressed.
fig.Compressor.e
You can use three-band equalizers (for high, middle, and low
frequency ranges) to adjust the sound.

Compressor (COMP)
Parameter Value Description
Attack EMPHASIS,
CRUSH EMPHASIS
Emphasizes the at-
tack of the sound.
CRUSH
Press the attack.
Type COMP SOFT 1–2,
COMP MED 1–3,
COMP HARD 1–2,
LIMITER 1–2,
EXPANDER 1–3 This changes Thre
and ratio values.
Time KICK 1–3,
SNARE1–3,
TOM 1–3,
CYM 1–2,
OTHER1–3 This changes Atck,
Hold, and Rels val-
ues.
Gain -15– +20 (dB) Output level of the
compressor
Parameter Value Description
Thre
(Threshold) -30–0 (dB) Volume level at
which compression
begins
Ratio 0.5:1–50:1 Compression ratio
Atck
(Attack) 0–255 (ms) Time from when the
volume goes up the
threshold level until
the compressor effect
applies
Hold 2–9999 (ms) Time compression is
kept
Rels (Re-
lease) 2–9999 (ms) Time from when the
volume falls below
the threshold level
until the compressor
effect no longer ap-
plies
Equalizer (EQ)
Parameter Value Description
Q 0.5–8.0
(only for MID) Width of the frequency
range
A higher Q narrows
the affected area.
Freq
(Frequency) 20–1k (LOW),
20–8k (MID),
1k–8k (HIGH) Point at which the
boost/cut will occur
Gain -15– +15 (dB) Amount of boost/cut
