Insert effect parameter functions
COSM Comp/Limiter
(COSM Compressor/Limiter)
This effect can be used to produce a long sustain sound by
evening out volume levels in the input signal. In addition,
you can also use it as a limiter to suppress only peaks in the
volume and prevent distortion.
A limiter is an effect that prevents distortion by suppressing
input signals in excess of a specific value (i.e., the threshold).
You can also get the same effect achieved with a compressor
by setting the threshold to a low value.
The BR-1600CD uses COSM technology to model four types
of compressor/limiter effects, which combine the functions
of a compressor and a limiter.
Effect On/Off OFF, ON
Sets the compressor/limiter to ON or OFF.
Type
Selects the compressor/limiter type.
Attack 0–100
(Active when BOSSCmp or D-Comp is selected.)
This parameter adjusts the strength of the picking attack produced
when the strings are played. Larger values will result in a sharper
attack, creating a more clearly defined sound.
Sustain 0–100
(When set to BOSSCmp, D-Comp)
Boosts low-level signals, adjusting the time over which sounds are
sustained. Higher values deepen the effect, resulting in a longer
sustain.
Threshold 0–100
(Active when Rack160 is selected.)
Adjust this parameter to match the input signal from your bass.
Compression will be applied to input levels in excess of this level.
The smaller the value set here, the lower the level at which the
limiter kicks in.
Input 0–100
(Active when VtgRack is selected.)
This parameter controls the input level. Increasing the value will
produce a deeper effect.
Ratio (Rack160) 1:1–20:1, inf:1 (VtgRack) 4:1–20:1
(When set to Rack160, VtgRack)
This adjusts the limiter compression ratio. Higher ratios produce a
stronger compression effect.
Attack Time 0–100
(Active when VtgRack is selected.)
This parameter adjusts the amount of time it takes for the
compression ratio set by “Ratio” to be reached once the input level
exceeds the set threshold level and compression begins. The larger
the value set here, the more rapidly compression will be applied.
Release Time 0–100
(Active when VtgRack is selected.)
This adjusts the time it takes for compression to be removed once the
signal level drops below the threshold. Higher values cause the
compression to be released more rapidly, making it easier to
distinguish the sound from successively played strings.
Tone -50–+50
(Active when BOSSCmp is selected.)
This parameter adjusts the tone. Higher values cause the high
frequencies to be boosted more, and this results in a harder sound.
Level 0–100
Adjusts the overall volume of the effect.
COSM Overdrive/Distortion
This effect distorts the sound to create long sustain
Effect On/Off OFF, ON
Turns the Overdrive/Distortion effect on or off.
Type
Selects the type of distortion.
Drive 0–100
Adjusts the depth of distortion.
Bass -50–+50
Adjusts the tone for the low frequency range.
BOSSCmp
Models the BOSS CS-3 compact effects
processor.
D-Comp Models the MXR dyna comp.
Rack160 Models the dbx 160x.
VtgRack Models the UREI 1178.
BLUES OD
This is a crunch sound of the BOSS BD-
2.
TURBO OD
This is the high-gain overdrive sound of
the BOSS OD-2.
BOOSTER
This is a booster that works very well
with COSM amps.
DISTORT
This gives a basic, traditional distortion
sound.
AMERCAN This models a Proco RAT.
GUV DS This models an Marshall GUV’ NOR.
OD-1 This is the sound of the BOSS OD-1.
TSCREAM This models an Ibanez TS-808.
DST+ This models an MXR DISTORTION+.
60S FUZ This models a FUZZFACE.
OCT FUZ This models an ACETONE FUZZ.
MUF FUZ
This models an Electro-Harmonix Big
Muff
π .
MT-2 This is the sound of the BOSS MT-2.
R-MAN This models a ROCKMAN.
HVY MTL This creates a heavier distortion sound.
