Step Filter
This is a filter whose cutoff frequency can be modulated in steps. You can specify the pattern by which the cutoff frequency will
change.
Parameter Value Explanation
Step 1–16 0–127 Cutoff frequency at each step
Rate Sync
OFF, ON If this is ON, the rate synchronizes with the tempo of the rhythm.
Tempo (Pattern) (P.53)
Tempo (System) (P.77)
Rate 0.05–10.00 [Hz] Frequency of modulation
Rate Note Note (P.167)
Attack 0–127 Speed at which the cutoff frequency changes between steps
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
Reso
0–127 Filter resonance level
Increasing this value will emphasize the region near the cutoff frequency.
Gain 0–+12 [dB] Amount of boost for the filter output
Level 0–127 Output Level
Enhancer
Controls the overtone structure of the high frequencies, adding sparkle and tightness to the sound.
Parameter Value Explanation
Sens 0–127 Sensitivity of the enhancer
Mix 0–127 Level of the overtones generated by the enhancer
