Pro Tools does not have real MPE support, yes (which btw is a shame…). But there is a workaround, if you set up multiple MIDI Tracks and route them to the Instrument. Roli has a good discription to this procedure.
But that does not work with StudioVerse Instruments AAX, it seems.
Please add the Multichannel MPE support to StudioVerse Instruments in AAX. Would be the perfect way to use MPE-ready VSTs in Pro Tools (like Equator2 from Roli).
