MFX Parameters
128
Parameter Value Explanation
S Release
0–124 Adjusts the time after the signal volume falls below the S Thres Level until compression is no
longer applied.
S Thres -60–0 [dB] Adjusts the volume at which compression begins
S Knee
0–30 [dB] This is a function that smooths the onset of compression from the uncompressed state; it
gradually applies compression starting earlier than S Thres.
Higher values produce a smoother transition.
S Ratio
1: 1, 1.5: 1, 2: 1, 4: 1,
16: 1, INF: 1
Compression ratio
S Gain 0–+18 [dB] Level of the output sound
Level 0–127 Output Level
Limiter
Compresses signals that exceed a specified volume level, preventing distortion from occurring.
Parameter Value Explanation
Release
0–127 Adjusts the time after the signal volume falls below the Threshold Level until compression is no
longer applied.
Threshold 0–127 Adjusts the volume at which compression begins
Ratio
1.5: 1, 2: 1, 4: 1,
100: 1
Compression ratio
Post Gain 0–+18 [dB] Level of the output sound
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
Sustainer
By compressing loud input and boosting low input, this effect keeps the volume consistent to produce a sustain effect without
distortion.
Parameter Value Explanation
Sustain
0–127 Adjusts the range in which a low input signal is boosted to a consistent volume.
Higher values produce longer sustain.
Attack 0–127 Time until the volume is compressed
Release 0–127 Time until compression is removed
