● 0104: Isolator
This is an equalizer which cuts the volume greatly, allowing you to add a special effect to the
sound by cutting the volume in varying ranges.

Description
These boost and cut each of the High,
Middle, and Low frequency ranges.
At -60 dB, the sound becomes
inaudible. 0 dB is equivalent to the
input level of the sound.
Turns the Anti-Phase function on and
off for the Low frequency ranges.
When turned on, the counter-channel
of stereo sound is inverted and added
to the signal.
Adjusts the level settings for the Low
frequency ranges.
Adjusting this level for certain
frequencies allows you to lend
emphasis to specific parts. (This is
effective only for stereo source.)
Settings of the Anti-Phase function for
the Middle frequency ranges
The parameters are the same as for the
Low frequency ranges.
Turns Low Booster on/off.
This emphasizes the bottom to create a
heavy bass sound.
Increasing this value gives you a
heavier low end.
Depending on the Isolator and filter
settings this effect may be hard to
distinguish.
Output Level
Description
Center frequency at which the lower
range will be boosted
Amount by which the lower range will
be boosted
Width of the lower range that will be
boosted

Output level
Description
Filter type
Frequency range that will pass through
each filter
Lpf: Frequencies below the cutoff
Bpf: Frequencies in the region of the
cutoff
Hpf: Frequencies above the cutoff
Notch: Frequencies other than the
region of the cutoff
Amount of attenuation per octave
-36 dB: Extremely steep
-24 dB: Steep
-12 dB: Gentle
Cutoff frequency of the filter
Increasing this value will raise the
cutoff frequency.
Filter resonance level
Increasing this value will emphasize
the region near the cutoff frequency.
Amount of boost for the filter output
On/off switch for cyclic change
How the cutoff frequency will be
modulated
Tri: Triangle wave
Sqr: Square wave
Sin: Sine wave
Saw1: Sawtooth wave (upward)
Saw2: Sawtooth wave (downward)

MIDI Implementation
Description
When this is set to "note," the effect is
synchronized with the tempo.
