I just had to go through a lengthy laborious entry procedure to add DIVISIMATE as DEVICE and use it.
I had to create 32 device entries.
In Ableton and Cubase I had to do none of this. I didn't even have to create any device at all before I could start using DIVISIMATE.
Divisimate uses up to 32 MIDI ports to operate. And for each port of DIVISIMATE I need in a project in S1, S1 requires me to create an entry.
