What is pitch shifting

• Wikipedia

Learn feature

The Pitch block has a Learn function. Turn it on, play a note, hold it. The Axe-Fx II sets the key according to the note you played. Source

Detune

In general: detune up and down the same amount, between +/-5 and +/-10, delay the voices for more width (7 ms), set mix at 25% or lower, turn down HiCut Freq to 8k or lower, place the block after the Amp block but before the Cab block, pan the voices hard left and right. Check for phase cancellation when running in mono.

Octaver

If you need an Octaver effect (1 octave down voice), set the pitch shifter to Fixed Harmony, 1 octave down. Alternatively use the Ring Modulator (FX block).

Position of the Pitch Shifter block

Cliff: "When going direct, pitch shifting often sounds best when placed BEFORE the cab block. The factory presets may have the block doing the shifting (pitch or multidelay) after the cabinet block. Try moving the pitch before the cabinet block for smoother results." Background (source: Bakerman): "The pitch block basically shifts the entire cab freq. response up/down if it's after cab. A slight detune might sound about the same either way but with a half step, whole step, etc. the difference becomes more apparent."

Harmony scales

The manual contains a table with the harmony scales, see Harmony scales.
