MFX Parameters
94
Parameter Value Explanation
Boost Sw
OFF, ON Turns Low Booster on/off.
This emphasizes the bottom to create a heavy bass sound.
Boost Lv
0–127 Increasing this value gives you a heavier low end.
Depending on the Isolator and filter settings this effect may be hard to distinguish.
Level 0–127 Output Level
Low Boost
Boosts the volume of the lower range, creating powerful lows.
Parameter Value Explanation
Boost Freq 50, 56, 63, 71, 80, 90, 100, 112, 125 [Hz] Center frequency at which the lower range will be boosted
Boost Gain 0–+12 [dB] Center frequency at which the lower range will be boosted
Boost Wid WIDE, MID, NARROW Width of the lower range that will be boosted
Low Gain -15–+15 [dB] Amount of boost/cut for the low-frequency range
High Gain -15–+15 [dB] Amount of boost/cut for the high-frequency range
Level 0–127 Output Level
SuperFilter
This is a filter with an extremely sharp slope. The cutoff frequency can be varied cyclically.
Parameter Value Explanation
Type
LPF, BPF, HPF, NOTCH 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
Slope
-12, -24, -36 [dB] Amount of attenuation per octave
-12 dB: Gentle
-24 dB: Steep
-36 dB: Extremely steep
Cutoff
0–127 Cutoff frequency of the filter
Increasing this value will raise the cutoff frequency.
Resonance
0–100 Filter resonance level
Increasing this value will emphasize the region near the cutoff frequency.
