15: FILTER
Cuts high- or low-frequency sound. With overdrive, it can modulate the cut-off frequency.
Parameter Value Descriptions
Cutoff 0–127 Control of the cut-off frequency
Resonance 0–127 Rate of emphasis and peculiarity on sound component at the cut-off frequency
Rate 0–127 Vibration cycle of the cut-off frequency
Depth 0–127 Vibration depth of the cut-off frequency
Drive 0–127 Rate of distortion
FilterType LPF, LPF (Low Pass Filter): cuts off high-frequency sound
HPF HPF (High Pass Filter): cuts off low-frequency sound
In addition, if you press the PAGE buttons, "Knob," "Velo" and "Pedal" are displayed. You can then select the parameters to be
controlled with the EFFECTS CONTROL knob, the strength (velocity) used in hitting a playing surface, and the expression pedal.

16: ISOLATOR
Boosts or eliminates the sound at low, medium, or high frequencies.
Parameter Value Descriptions
Low -64–+63 Amplification/elimination of the sound at low frequencies
Mid -64–+63 Amplification/elimination of the sound at medium frequencies
High -64–+63 Amplification/elimination of the sound at high frequencies
In addition, if you press the PAGE buttons, "Knob," "Velo" and "Pedal" are displayed. You can then select the parameters to be
controlled with the EFFECTS CONTROL knob, the strength (velocity) used in hitting a playing surface, and the expression pedal.
