Yeah this should be possible. From MSS you would have to create a generator and then create a mapping that maps that generator to some CC output. I'm not familiar with Studio One but I did come across this tutorial that covers how to map the MIDI output of a different MIDI plugin to Studio One
http://www.cableguys.de/midi-shaper-studio-one.html . Should be pretty similar for MSS.
I'll attach a sample MSS program that generates some tremolo and maps it to CC7.
