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
X/Y-switching occurs at block level, not on preset level.
The X/Y state of an effect can vary per Preset scene.
There's no crossfading when switching between X and Y. If you want crossfading, you can use Scene controllers as an alternative to X/Y switching.
In Axe-Edit press the "x" key to switch a block between X and Y.
Axe-Edit shows the X/Y-states of the blocks on the grid without needing to select the block first.
MFC-101: X is green, Y is red. If you prefer the default state to be green, use Y as the default state.

An assigned modifier always applies to both block states: X and Y. It's not possible to have different modifier settings for X and Y.

Recall Effect always imports the entire block: X and Y. You can't recall only X or Y.

When tweaking, X/Y is an easy way to compare sounds. Example:
1. Go to the Amp block, state "X".
2. Double-click the "Y" knob on the front panel, to copy the "X" settings to "Y".
3. Select "Y" and re-select the amp type to reset the model's more advanced settings to default. Or doubleclick Bypass and to reset the block entirely.
4. Now alternate between X and Y on every tab page of the Amp block to see the differences.
You can also do this in Axe-Edit.

If you have an effect block with X/Y, you can configure the floor controller to turn engage 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/switch-link functionality.
