This is a filter that cuts the high-frequency
region above the cutoff frequency.
This is the most common type of filter, and is
used to cut part of the overtone components,
making an originally bright timbre sound more
mellow (darker).
When the “Filter Type” is Low Pass Resonance,
the cutoff will have a steeper slope.
Resonance Use the Filter Resonance to boost the part of the sound spectrum
around the cutoff frequency.
LFO Depth Intensity of the Vibrato (LFO).
LFO Speed Speed of the Vibrato (LFO).
LFO Delay Delay time before the Vibrato (LFO) begins, after the sound starts.
