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-

In the FILTER EDIT menu you have the
option of freely defining the base note
under Keyfollow BASE.

all of the frequencies of a signal except
for a narrow frequency band around the
cutoff to pass. The term "notch" is fairly
