Hi OH/EX/OH, have You tried to set the synchronization of Ableton midi output in options, midi preference, output Elektron Analog Four?
I have set a correction to -52 ms and all work flawlessly.
I think this video can help you, http://youtu.be/DDzjnumzI_Q , from 0:40 to 1:20.
I hope you find it useful, bye.
