The Parameters
FILTER SECTION/MENU
Filter 1
KEY FOLLOW Determines the extent to
which the filter frequency follows the
pitch (Note Number) and the Pitch Bend.
Depending on the FILT SELECT setting,
KEY FOLLOW affects the first filter, the
second filter or both filters. The function
uses C 1 (MIDI Note Number 36) as a neu-
tral starting point or base note: Regard-
less of the KEY FOLLOW value, the filter
frequency is not influenced at this pitch.
In the FILTER EDIT menu you have the
option of freely defining the base note
under Keyfollow BASE.

FILT 1 MODE Selects the operating
mode of the indicated filter:
LP The low pass filter suppresses fre-
quencies higher than the CUTOFF fre-
quency (see appropriate section) and
allows the lower frequencies through.
HP The high pass filter works in the
opposite manner of the low pass filter: It
suppresses the lower frequencies in a sig-
nal and lets the higher frequencies pass.
BP The band pass filter suppresses both
ends of the tonal spectrum and allows
only a narrowly defined bandwidth of
the original sound to pass.
BS The band stop filter, band reject fil-
ter or notch filter works in the opposite
manner of the bandpass filter. It allows
all of the frequencies of a signal except
for a narrow frequency band around the
cutoff to pass. The term “notch” is fairly
descriptive; you might say this filter
chops a notch out of the sound spec-
trum.
