As I mentioned, it Might be just my setup that’s garbling the MPE messages.
Sensel and Presonus got together and they had the Morph working fine.
You might want to find someone near you with S1 and take your Morph over to check that it Does work …
I’ll be building a new music PC soon. This one I built in 2012.
Then I’ll see if my Morph works with S1 or not.
It appears to be working in Bitwig, I haven’t tested it since Bitwig 4 came out.
