Project from Ableton to Digitakt – Elektron Gear

Hi,
I found in a hard disk a bunch of old projects, and I would love to integrate some of them into my Digitakt (2). Some tracks are midi, some others are audio it’s quite a mess … I wonder if some of you have an idea of how properly do that and try to eventually have a look like track from Ableton to Digitakt.
For now, for simple synth sounds I do it from scratch and by ear, and reproduce midi trig information by hand. And for more complexe sounds like to much LFO and randomness, I accept to make it as a few bars sample, and play it as it is.
So two technics there : reproducing step by step (too long and sometimes we just can’t do it, Ableton has infinite possibilities in a digital world) OR just import long samples into the hardware and play it, not very fun I would like to be able to play with it as much as it is possible.
Any method ?
Thanks
