Even if you have loaded The XSP with my presets
the XSP ignores this until you do the following:
(a trick that is not in the X-Session or Enigma manual):

1. Press the tiny button "A" at the back with a pin or toothpick
2. Let go
3. Press the Left Play/Pause button

You may have to exit Traktor for this to work.

To use XSP with ableton like you have been doing until now,
do the same except press the left >> button (in step 3) instead of Play/Pause button.
If this does not work you will have to restore factory settings
1. Press the tiny button "A" at the back with a pin or toothpick
2. Let go
3. Press the reset button on the back

I stored my preset in the Play/Pause button
In fact you may have noticed this when you were in Enigma.
But i could have stored it anywhere
(10 possible, because 10 buttons)
.

In fact, i did store presets elsewhere.
Instead of the Play button try the headphone buttons.
The Left one lets you control FX of four decks.
The Right one lets you control FX of four decks.

The << buttons are the same as headphone buttons
except decks ABCD are rearranged
