Good replies, all around. I own only the Synthstrom Deluge now, and don't really feel I need more gear. But I do want a recording solution that I can bring on stage as well for gigs, and since I have extensive experience with the Octatrack from before, and a brief but intense experience with the Digitakt, I know these are my two options. Others, such as the MPC Live, Toraiz and so on, are off the table.
The short time I had with the Digitakt, it just felt like whatever came out of it, sounded like a more polished and well-rounded production. As if the Elektron elves had engineered my stuff to sound almost better than it deserved. I hear others say the same thing, so it's interesting to put this suggestion on its edge and just flat out ask, if you isolate it to the sound and just the sound.
Cause that's my consideration - I love the Octatrack. But the one thing the Digitakt did better, at least in my head, was to get me to a sound I much more preferred. Was it the elves, just a fortunate combinations of pushes and turns, or stuff within the Digitakt that just worked better with my music? I have no idea, and I'm not ruling out it's all in my head.
