At this moment all major daws except Studio One, Live and Fruity Loops are supporting MPE.
There are at least six hardware controllers and 37 software synths that has MPE built in it, among them are Omnispere, Synthmaster, UVI Falcon, Reaktor, Alchemy, Halion and many more.
It will only be a matter of time and all the big companies will have a hardware controller with MPE, because the competition will have it too.
So Presonus; what are your plans about this subject?
I'm now on version 4 but if I'm gonna buy a kontroller with MPE in it in the near future I might step over to another daw and leave Studio One behind.
Look here what's on the market now with MPE already; https://roli.com/mpe
