When using Amp Modeling, the control knobs (GAIN/MID, BASS, TREBLE, VOLUME) and Value dial will be active. The VOLUME knob can still be used even when Amp Modeling is “OFF.” If SYNTH is selected as the type, the control knobs will control oscillator selection, VCF setting, direct level, and synth level respectively. Types marked by an asterisk* can also be selected by the amp modeling selector. In order to take full advantage of the characteristics of Amp Modeling, we recommend that you use it in conjunction with Cabinet Modeling when listening through headphones or when recording from line output.

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 up 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 PX4D 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) Each delay type, (1, 2, 3, 4, 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) SLAP1…5 VALUE (Value Dial) Slap-type delay whose delay time is 1/4 of the interval at which you press TAP. DELAY1…5 Stereo delay.
