I used Brainspawn's Forte to control Arturia's CS-80 and MiniMg. I find Forte very effective in controlling soft synths in real time. There is a link here to a youtube video with myself playing Saga's Don't Be late. When they recorded this song Jim Gilmour was playing a CS-80, polyMg, Mg voyager and an electric piano. The sound coming out of Arturia's CS-80 and MiniMg is almost identical.
