FILTER 1
KEY FOLLOW
Determines the extent to which the filter fre-
quency follows the pitch (Note Number) and the
Pitch Bend. The function uses C 1 (MIDI Note
Number 36) as a neutral starting point or base
note: Regardless 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 fil-
ter:
- LOWPASS The low pass filter suppresses
frequencies higher than the CUTOFF frequen-
cy (see appropriate section) and allows the
lower frequencies through.
- HIGHPASS The high pass filter works in the
opposite manner of the low pass filter: It sup-
presses the lower frequencies in a signal and
lets the higher frequencies pass.
- BANDPASS The band pass filter suppresses
both ends of the tonal spectrum and allows
only a narrowly defined bandwidth of the
original sound to pass.
- BANDSTOP The band stop filter, band reject
filter or notch filter works in the opposite
manner of the bandpass filter. It allows all of
the frequencies of a signal except for a nar-
row 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 spectrum.
