By combine the HPF setting of filter 1 with
the LPF setting of filter 2, it is possible to create
a BPF (Band Pass Filter) response that allows
only frequencies that fall between the cutoff of
the HPF and LPF to pass. In this case the cutoff
of the LPF must be set at a higher frequency
than that of the HPF. It is also possible to set
both filters to "LPF" and the same cutoff fre-
quency, resulting in a steep 24-dB per octave
filter slope.

ENVELOPE GENERATOR," page 75.
Bandpass Filter (HPF + LPF) Response
Cutoff
Summary: Sets the cutoff frequency of the selected
filter.
Settings:
0...127 (LPF)
0...114 (HPF)
Procedure: Use the and cursor keys to
select the Cutoff parameter. Use the [DATA EN-
TRY] control, [-1/NO] and [+1/YES] keys, or
numeric and [ENTER] keys to select the desired
cutoff frequency.
Filter 1 or Filter 2 can be selected by holding
the [SELECT] key and pressing the numeric [9]
or [6] key, respectively.
Details: Lower cutoff values produce a lower cutoff
frequency and higher values produce a higher
cutoff frequency.
With an LPF response, a lower cutoff fre-
quency reduces the range of high frequencies
passed, making the sound "darker" or "rounder."
With a HPF response, a higher cutoff fre-
quency reduces the range of low frequencies
passed, making the sound "thinner" or "sharper."
