HPF (High Pass Filter Cutoff)
The HPF setting determines the cutoff frequency of the
High Pass Filter. Frequencies above the setting are
passed while those below are cut off. Turning the knob
to the right increases the HPF Cutoff frequency,
resulting in a brighter sound.
Settings: 0 ~ 127
This High Pass Filter is applied to the signal after the mixer, and is different than
the one available in the VCF Type.
VCF Type
The VCF Type setting determines the type of filter used
by the VCF. The VCF passes only a specified range of
frequencies while cutting off the rest, to give you
versatile control over the timbre. There are six types of
filters, as described below.
Settings: LPF24, LPF18, LPF12, BPF, HPF12, BEF
LPF24, LPF18, LPF12
The Low Pass Filter passes only those frequencies below the
specified cutoff point. A cutoff curve of 24dB/octave (LPF24),
18dB/octave (LPF18) and 12dB/octave (LPF12) can be
selected.

BPF
The Band Pass Filter passes only those frequencies in the
specified range, with a cutoff curve of 12dB/octave.
HPF12
The High Pass Filter passes only those frequencies above the
specified cutoff point, with a cutoff curve of 12dB/octave.
BEF
The Band Eliminate Filter passes only those frequencies
outside the specified frequency range. The Resonance setting
(see page 65) determines the eliminate range.
The filters listed above apply to the signal output from the HPF located between
the Mixer and VCA. For more information about the signal path, see page 10.
