DLY adjusts the length of a delay line from zero to 510ms in 2ms steps.Optimal
DLY
pitch shift occurs when DLY is about 40ms.
FBK controls the amount of positive feedback from the output of the pitch shift
FBK
to the input of the pre-delay line. The control is adjustable from 0 to +99%. Some
very useful efects can be obtained by combining pitch shift, delay, and feedback.
GLD changes the pitch continuously over a range of -2 octaves (25%) to +1
GLD
octave (199%). This allows a glissando to be performed, either manually or via
MIDI.
FIN
FIN adjusts pitch continuously over a range of -2 octaves to +1 octave. This
allows a glissando to be performed, either manually or via MIDI.
BNPS is a band-pass filter which rolls off the frequency responce of the audio
before the splicing algorithm. The -3dB point is 100 Hz. The purpose of the band-
pass filter is to give the pitch shifter less information than it actually needs to
decide when to make the splice. Typically, this will further improve the perform-
ance of the pitch shifter.
