About the Intelligent Pitch Shifter The Intelligent Pitch Shifter creates musically useful harmonies by varying the amount of pitch shift according to the note you play and the key in which you are playing. For example if you select a pitch shift of a 3rd upward in a major key (MAJ3UP), the amount of pitch shift will vary automatically between three semitones (a minor third) and four semitones (a major third). • When MAJ3UP is used with a key setting of C The pitch created by the intelligent pitch shifter is shown in parenthesis ( ). The PX4 provides seven types of intelligent pitch shifting, with intervals of a 3rd, 4th, 5th, and 6th. (For the 3rd, you can select either the upper or lower part, and a major or minor key.) If your instrument is not tuned correctly, the results may not be as you expect. In this case, re-tune your instrument. The intelligent pitch shifter will function when you play individual notes. It cannot produce the effect for chords.

DLY (Delay Modeling) For each type, 1, 2, 3, 4 and 5 have different amounts of feedback. The delay time is set by the interval at which you press the TAP button twice. The specified delay time can be a maximum of 500 ms for SLAP or a maximum of 2 sec for MULTI, and can be checked by holding down the TAP button TYPE (π/† button) VALUE (Value Dial) Slap-type delay whose delay time is 1/4 of the interval at which you press TAP DELAY1, 2, 3, 4, 5 Stereo delay PPDLY1, 2, 3, 4, 5 Dual-tapped ping-pong delay that pans the sound to Adjusts effect level. left and right (0...10.0) ECHO, 2, 3, 4, 5 Tape echo simulation with a warm tone MULTI1, 2, 3, 4, 5 Dual-head tape echo simulation with special stereo design (creates a spacious reverberation)
