I have found the solution for X1's Beat Jump to behave exactly like the S4 Factory default mapping - jumping in the Beat value set before jumping. Not sure if this has been posted previously....do start with X1 Factory default mapping and try the following -

Preferences - Controller Manager and you should find a total of 12 (Twelve) Size Selectors.

Goto the 11th & 12th Size Selector (counting down from the top of the list) and make changes to the following settings below -

Size Selector (Size) - Select Loop for Deck A

Size Selector (Size) - Select Loop for Deck B

Change The Value to : Loop

Fixing Beat Jump:

Hotcue Play: 

----------------------

To switch to play when holding a hot cue button, you need to use modifiers.

I have mapped the FX1 button to activate play, and FX2 button to activate pause while pressing a hot cue button for the corresponding deck.

You need to add an 'Add In...' for each hot cue button. Choose modifier 7 for deck A hot cue buttons, choose modifier 8 for deck B. Type Button, interaction mode Hold, set to value 1. (same parameters for all hot cue buttons).

Then you need to link the FX buttons: choose 'Add In..', Play/Pause for FX button 1 (deck A). Set modifier condition 1 to M7 (modifier 7), value 1. Type Button, interaction mode Direct. Under button options set to value 1. For FX button2 (pause) do the same but choose set to value 0 to stop playback.

Do the same for deck B, but for deck B you select modifier condition M8.

Additionally you can add 'Add Out...' mappings to light up the FX buttons while you hold a hot cue button depending on the actual play/pause mode:

Map the Play/Pause add out to FX button 1 and set modifier conditions to M7=1 (deck A) or M8=1 (deck B). Type LED, Interaction mode Output, assignment Deck A / Deck B. For FX2 button do the same but check 'Invert' under LED options.

I included my mapping file. (other changes in my mapping: pitch bend without shift. beat jump with shift).
