AR + iPad vs Octatrack + MPD (or other pad controller)


(see 8:00 for my fave sounding track, but the whole thing is awesome!)

Above are links to sounds similar to what I’m looking to achieve.
Most of there work is ITB, I’m looking for an OTB setup. I’m especially interested in the squishy, wet sounds.

AR + OT would be ideal but can only get one at the moment.

Would one of these boxes even be able to do what I’m looking to do?
Or is software the best way to achieve these kinds of sounds?

Thanks!
