M300 Owner's Manual-English - Lexicon

The Algorithms and their ParametersThe Mono Pitch Shift Algorithm has several useful effects, including predelay,feedback, and glide. The pitch shifter in the 300 includes a pitch detection featurewhich automatically adjusts the period of the splices to match the pitch ofincoming signals. This feature makes the splicing intelligent, and greatly reducesthe artifacts associated with pitch shift. the Mono Pitch Shift program, eachchannel splices independently. It takes about 40 ms for the pitch detector toobtain an optimal pitch value. Setting the DLY control to this value will give thesmoothest pitch shift. Shorter values can be used for special effects, or whenextra delay cannot be tolerated.Mono Pitch ShiftGeneral 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.Mono Pitch Shift AdjustmentsDM: PCH DLY FBK-2Oct to M7+48¢ 0-510ms 0-98%, MaxMchB GLD FIN BNPS-2Oct to M7+48¢ +96 cents On/OffEffect Naming PageMono Pitch ShiftParametersFeedbackShifterBandpassΣPITCH FINE GLIDEDelayMono Pitch Shift Adjustments PagePCH adjusts pitch interval. The exact tuning can be altered by FIN, and the exactpitch shift in intervals and cents is displayed. FIN must be set to the exact middleof its range if perfect pitch intervals are to be obtained.PCHIn the long display, fine pitch is shown by the number of cents added to, orsubtracted from, the semitone intervals. Remember that PITCH will produceexact intervals only if FIN is centered. The rightmost character in the long displayis an asterisk (*) if FIN is centered, and a '+' or '-' otherwise. When the VALUEkey turns on the short value display, FIN is not shown in cents, but as a numberranging from -32 to +32 in order to give a clear indication of how much the pitchshift has been changed. When '**' is shown, FIN is centered and inactive. As arule, 1 count of FIN is worth 2 cents near 200%, 3 cents near 100%, 6 cents near50%, and 12 cents near 25%.4-29
