The Algorithms and their ParametersStereo Pitch ShiftStereo Pitch Shift is a stereo or two-channel mono pitch shifter with severaluseful effects, including predelay, feedback, and glide. These are independentlyadjustable for each channel. The pitch shifter in the 300 includes a pitchdetection feature which automatically adjusts the period of the splices to matchthe pitch of incoming signals. This feature greatly reduces the artifacts associatedwith pitch shift. In stereo mode both channels are linked, and the sum of thetwo channels (L & R) is used in the pitch detector. In mono mode each channelsplices independently. In either case it takes about 40 ms for the pitch detectorto obtain an optimal pitch value. Setting the LDLY and RDLY controls to thisvalue will give the smoothest pitch shift. Shorter values can be used for specialeffects, or when extra delay cannot be tolerated.General DescriptionThere are three interacting controls for pitch described below: Glide, PitchInterval, and Fine Pitch. Adjusting any pitch control activates a long display thatshows the pitch percentage, the musical interval, and any fine adjustment incents. Always use this long display when matching Glide to Pitch Interval andFine Pitch.Stereo Pitch Shift Mode, Pitch and EffectsMODE GLDL - GLDRMono/Stereo -2 Oct to +M7+48¢ - -2 Oct to +M7+48¢PCHL FINL PCHR FINR-2 Oct to +M7+48¢ + 100 cents -2 Oct to +M7+48¢ + 100 centsStereo Pitch Shift Delay and FeedbackLDLY LFBK RDLY RFBK0-510ms 0-98%, Max 0-510ms 0-98%, MaxBNPS SYNC - -On/Off On/Off - -Effect Naming PageStereo PitchShift ParametersFeedbackBandpass Sync ModeMono orStereoΣΣShifterPITCH FINE GLIDEShifterPITCH FINE GLIDEL DelayR DelayFeedback4-15
