Explanation
FILTER
[HPF] knob
Sets the cutoff frequency of the -6dB/Oct high-pass filter.
[TYPE] knob
Select the filter type.
LPF: A -24dB/Oct low-pass filter. This cuts off frequencies above the cutoff frequency. Cutting off the
high frequencies makes the sound more mellow. This is the most frequently-used type.
BPF: A -12dB/Oct band-pass filter. This cuts off frequencies except for those around the cutoff frequency.
This filter type is useful for making sounds with a unique character.
HPF: A -24dB/Oct high-pass filter. This cuts off frequencies below the cutoff frequency. This filter type is
useful for creating percussion sounds and the like that have a distinctive high end.
