Having the exact same problem right now, I am composing with Live mainly so it is hard to acommodate AK sequencer.

I am thinking of developing some ideas with the elektron first and then record them as audio clips, then add content with live clips.

The other option which I dont like is just sequencing the Ak with Live, seems like a waste but depending on what I am doing it might be faster.

But certainly being able to change patters by track, and not for all the 4 tracks, would be great.
