Stereo Pitch Shift
General Description
Stereo Pitch
Shift Parameters
Stereo Pitch Shift is a stereo or two-channel mono pitch shifter with several
useful effects, including delay, feedback, and glide. These are independently
adjustable for each channel. The pitch shifter in the 300L 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 LDL and RDL 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 two interacting controls for pitch described below: Pitch Interval, and
Fine Pitch. Adjusting any pitch control activates a display that shows the musical
interval, and any fine adjustment in cents.
