This is a high-pass filter that passes the high frequencies and cuts the low frequencies.

Here you can adjust the amount of time-varying change (envelope) for the volume.

[LEVEL] slider
(Square wave/Asymmetrical pulse wave).
Turns the sub-oscillator on/off.
Adjusts the volume of the sub oscillator.
Adjusts the volume of the noise.
EXPLANATION
Specifies the cutoff frequency of the high-pass filter.
Frequency components below the cutoff frequency are cut.
EXPLANATION
Specifies the cutoff frequency of the low-pass filter.
Frequency components above the cutoff frequency are cut,
making the sound mellower.
Resonance boosts the sound in the region of the filter's cutoff frequency.
Higher settings produce stronger emphasis, creating a distinctively "synthesizer-
like" sound.
Selects the polarity (direction) of the envelope.
Adjusts the depth by which the 8 ENV (envelope) controls the cutoff frequency.
Uses the 3 LFO to vary the cutoff frequency.
Adjusts the way in which the pitch of the note affects the cutoff frequency (key
follow) when using the keyboard to control cutoff frequency. If this slider is
moved upward, the cutoff frequency rises as you play higher notes.
EXPLANATION
Selects whether the volume is controlled by 8 ENV (envelope) or by the gate
signal.
Adjusts the volume of the patch.
