Modulation FX Parameters
4: STEP FILTER
This is a lter whose cuto frequency can be modulated in steps. You
can specify the pattern by which the cuto frequency will change.
You can use MFX CONTROL to restart the step sequence from the
beginning (p. 31).

If this is ON, the modulation is
synchronized to the tempo of the
rhythm (owner’s manual p. 24).

Filter type
Frequency range that will pass
through each lter
LPF: frequencies below the cuto
BPF: frequencies in the region of the
cuto
HPF: frequencies above the cuto
NOTCH: frequencies other than the
region of the cuto
Filter Slope -12, -24, -36 [dB]
Amount of attenuation per octave
-12 dB: gentle
-24 dB: steep
-36 dB: extremely steep

Filter resonance level
Increasing this value will emphasize
the region near the cuto frequency.
Filter Gain 0–+12 [dB] Amount of boost for the lter output
Level 0–127 Output level
5: ENHANCER
Controls the overtone structure of the high frequencies, adding
sparkle and tightness to the sound.
