Good question. Studio One has innovated in a number of ways, but MPE support is increasingly in the category of essential DAW functions and it's not there. My Roli Seaboard is a powerful musical tool, and MPE is the obvious, already available immediate future for more complex touch response in digital music making. In Studio One, right now, its functionality is extremely limited. There are possible workarounds, but the simplest one, I'm afraid, is to just use a different DAW for a lot of projects. That is a pity. Studio One will inevitably need to add MPE functionality, and sooner would be better than later, yes? My two cents, hoping that a few more pokes will provoke a response in the form of an update. Thanks...
