Stereo Pitch Shift - Lexicon 300 - V3.0 REV 1 Owner's Manual

Stereo Pitch Shift is a stereo or two-channel mono pitch shifter with several
useful effects, including predelay, feedback, and glide. These are independently
adjustable for each channel. The pitch shifter in the 300 includes a pitch
detection feature which automatically adjusts the period of the splices to match
the pitch of incoming signals. This feature greatly reduces the artifacts associ-
ated with pitch shift. In stereo mode both channels are linked, and the sum of the
two channels (L & R) is used in the pitch detector. In mono mode each channel
splices independently. In either case it takes about 40 ms for the pitch detector
to obtain an optimal pitch value. Setting the LDLY and RDLY controls to this
value will give the smoothest pitch shift. Shorter values can be used for special
effects, or when extra delay cannot be tolerated.
There are three interacting controls for pitch described below: Glide, Pitch
Interval, and Fine Pitch. Adjusting any pitch control activates a long display that
shows the pitch percentage, the musical interval, and any fine adjustment in
cents. Always use this long display when matching Glide to Pitch Interval and
Fine Pitch.
