This is a filter with an extremely sharp slope (attenuation characteristics). The cutoff frequency can be varied cyclically.
| Parameter | Value | Explanation |
|---|---|---|
| CUTOFF | 0–100 | Sets the frequency range in which the filter works (the cutoff frequency). Higher values increase the frequency range. |
| RESONANCE | 0–100 | Adjusts the filter’s resonance level. The larger the value, the more that the frequency range set in CUTOFF is emphasized. |
| FLT TYPE | Sets the filter type. |
|
| LPF | A low-pass filter. This filter lets frequencies pass through that are higher than the frequency range set in CUTOFF. | |
| BPF | A band-pass filter. This filter lets frequencies pass through that are near the frequency range set in CUTOFF. | |
| HPF | A high-pass filter. This filter lets frequencies pass through that are higher than the frequency range set in CUTOFF. | |
| DEPTH | 0–100 | Sets the depth of the effect. |
| RATE | 0–100 | Sets the cycle (period) of the effect. |
| SYNC | OFF, ON | When this is ON, the effect sound synchronizes with the tempo. |
