Cubasis and Fugue Machine I’m I missing something?

Hello there.i just bought Fugue Machine from the AppStore to control SynthS in cubasis.fugue is a midi sequencer with 4 play heads each f witch can be assigned to a different midi and output.i set up 2 instruments in cubasis and routed the inputs to Fugue.in theory the play heads in Fugue should play each instrument in sync.but it doesn’t happen in cubasis.i need to choose the instrument track befor it plays…tried it with bs-16i standalone and it works like it should.but in cubasis unless I select the track.pleas give this video a watch for better understanding https://youtu.be/h6yXiUPFfmc
