X/Y switching (legacy)

User contributions

Idea behind X/Y-switching

• Cliff: "The idea behind X/Y is that people often have multiple distortion/chorus/delay/etc. pedals on their board but they rarely have more than one on at a time. So rather than creating more instances of effects, which sucks up CPU, have each instance capable of more than one sound." Source

Switching, crossfading and spillover

• Switching occurs at block level using a MIDI CC, not on preset level.
• There's no crossfading when switching between X and Y. If you want crossfading, you can use Scene_controllers#Scene_Controllers as an alternative to XY switching.
• X/Y doesn't support delay and reverb spillover. Source
• The selected state of the effect (X or Y) is saved with the preset.
• On the MFC-101 X is green, Y is red. If you prefer the default state to be green, use Y as the default state.

X/Y and preset scenes

• The X/Y state of an effect can vary per scene (firmware 9 and later).

Configuring floor controllers for X/Y-switching

• If you have an effect block with X/Y, you can configure the floor controller to turn on the effect in either X or Y mode. Source
  1. IA Switch 1, ON message: DELAY 1 ON, DELAY 1 X (CC#47:127, CC#106: 127)
  2. IA Switch 1, OFF message: DELAY 1 OFF, DELAY 1 X (CC#47:0, CC#106: 127)
  3. IA Switch 2, OFF message: DELAY 1 ON, DELAY 1 Y (CC#47:127, CC#106: 0)
  4. IA Switch 2, OFF message: DELAY 1 OFF, DELAY 1 Y (CC#47:0, CC#106: 0)
• Or use the controller's group/link feature.

Modifiers

• An assigned modifier applies to both block states: X and Y. It's not state-dependent.

Recall Effect

• Recall Effect always applies to both states. You can't recall only X or Y.

Using XY to compare sounds

• When tweaking, XY can be used to compare sounds before/after.
