To add to this discussion, one could add a simple DAW as a slave like Cakewalks MC5, or Reaper to tempo lock the VSTi, and then send the midi data from RB to say MC5 thru rewire, and then out of jamstix.

Until MC3, and or Sonar 4 Cakewalk was also a DX based and therefore used a VST wrapper to make VST and VSTi plugs work as DX and DXi plugs, that was nice but kind of shakey.
