02: 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.

03: FILTER+DRIVE
This is a low-pass filter equipped with overdrive. It cuts the upper range and adds distortion.

Value Explanation
-64–+63 Increases/decreases value for all steps
0–127 Cutoff frequency at each step
Increasing this value will raise the cutoff frequency.
OFF, ON OFF: Rate specified as numerical value
ON: Rate specified as note value
0–127, note Rate at which 8-step sequence is to be repeated
0–127 Speed at which the cutoff frequency changes between steps
LPF, BPF, HPF, NOTCH 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
-12 dB, -24 dB, -36 dB Filter slope (damping characteristics; amount of damping per octave)
-12 dB: gentle
-24 dB: steep
-36 dB: extremely steep
0–127 Filter resonance level
Increasing this value will emphasize the region near the cutoff frequency.
0–127 Output level
Value Explanation
0–127 Cutoff frequency of the filter
Increasing this value will raise the cutoff frequency.
0–127 Filter resonance level
Increasing this value will emphasize the region near the cutoff frequency.
0–127 Amount of distortion
