Pitch: position of the block on the grid

• 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 Cab block. Try moving the pitch before the Cab for smoother results."
• "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." (source: Bakerman)

Pitch: Poly or Mono tracking

• The Pitch Track parameter (Fixed Harmony and Whammy) offers: “Off”, “Poly”, and “Mono”. Poly tracking works best for shifting chords and/or lower amounts of shift. Mono tracking works best for shifting single notes and/or larger shift amounts.

Pitch: CPU priority

• Cliff: "Once the CPU usage crosses a certain threshold (which could happen if you are streaming audio) the pitch detection will slow down as the global pitch detector necessarily has a lower priority than the primary audio processing. If you change the Pitch Source to Local then the local pitch detector runs at the same priority as the audio." Source

Pitch: learn

• 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.

Pitch: harmony scales

• The manual contains a table that lists Harmony scales.

Pitch: arpeggiator

• The Arpeggiator mode uses 16 steps. Here's a trick to expand that to 32 steps.

Pitch: octaver effect

• If you need an Octaver effect (1 octave down voice):
  • set the pitch shifter to Fixed Harmony, 1 octave down, or
  • use the Ring Modulator effect in tracking mode, or
  • set the Pitch block to Octave Divide.

Pitch: detune effect

• Pitched detuning is a great alternative to a Chorus. There's no "swirl", associated with that 80's chorus tone. Use it in stereo for a very wide effect.
• In general: detune up and down the same amount, between +/-5 and +/-10, delay the voices for more width (let's say 7 ms), set mix at 25% or lower, put the block after the Amp block but before the Cab block, and pan the voices for a wide stereo effect. Beware of phase cancellation when running a mono rig.

Pitch: Whammy pedal

• Go here for tips about optimizing the curve of the expression pedal.
• You can engage a Whammy on the fly without using Auto-engaging a pedal.
  1. Put a Pitch block in line, set to Classic Whammy. Source: Global. Bypass Mode: Thru.
  2. Assign the Control parameter to your pedal's external controller.
  3. Assign the same external controller to the Mix parameter. Set Mix at zero. Modifier menu: Start 40, Mid 100, End 55, Slope 0, Scale 10, Offset 100.
  4. Make sure the Pitch block is engaged and save the preset.

Pitch: simulation of dropped tuning

• Use a Pitch block at the start of the grid and set it to Fixed Harmony. Select the desired voice. Set Mix to 100%, Tracking to On and adjust Track Adjust if necessary. Pitch Track: Poly.
• If you can't stand the latency (there always will be some latency), try Simeon's neat trick, explained here and here.

Pitch: shimmer effect

• The Shimmer effect raises the pitch of notes and reverberates them. Pioneered by Digitech (IPS 33 and other devices). Used a lot by U2's The Edge, among others.
• You can use the Pitch Shifter's Crystals mode (set to Reverse Feedback). Or use the Plexi Shift mode in the Multi Delay effect.
• A low-pass filter helps to keep the dry signal clear and separate from the shimmering notes.
• Attach an external controller to Input Gain to fade in the effect with a pedal.

Pitch: dive bomb

• The Axe-Fx II can simulate an automated dive bomb or rising pitch effect.
• On the Axe-Fx:
  1. Create a preset with a Pitch block after the Amp block.
  2. Set Pitch mode to Classic Whammy, Up|Dn 2 Oct., Pitch Track off, 100% mix.
  3. Enter the Modifier menu of the Control parameter in the Pitch block. Set Source to an external. Set Damping to 750, for starters.
  4. Enter the Modifier menu of the Bypass parameter in the Pitch block. Set Source to the same External controller as above.
  5. Save the preset.
• On the floor controller:
  1. Program a switch switch to send the External controller's CC.
  2. The switch can be latching or momentary, whatever works for you.
• To operate: select the preset. Press the switch (press and hold if it's a momentary switch) for the effect to kick in. Press again (or release) to stop, and bypass the Pitch block.
• You can also use your expression pedal instead of a switch. Use the corresponding External controller.
• Instead of a switch, you can also use Auto engage.
• You can adjust the length of the dive through the Damping parameter, use another Whammy mode, make it even more dramatic by adding a flanger, etc.
