This conversation has been going on for as long as the Octatrack has been in existence… Hell, this thread started in Jan '15.
Opinions range widely from “I wouldn’t trust the Octa for anything critical” to “It’s at least on par with RME interfaces”.
Elektron could maybe do the userbase (and their business!) a solid by doing a small comparison video – you know, content marketing and stuff As long as it’s some user on a forum doing the comparison, this thing won’t be put to rest. After all, it’s not like this is something unquantifiable.
My two cents: I think this OT throughput quality discussion is a case of the ‘MPC swing’. No matter if Roger Linn himself says that every other step is delayed by a few ticks, nothing else, there’s still a throng of believers ready to say it’s magic. In other words, the discussion has transcended reason and gone into the ‘feel’ realm, which is usually fine in the context of music, but with simple, quantifiable matters is just a way to drone on endlessly.
But I’ve never done any comparison, or even listened critically, so I might be wrong, and I don’t want to argue over this. Like I said, I’m not qualified.
