Project playing over bluetooth?

hi.
I have never been able to … and am probably guessing that i can’t due to the fact that the project is basically all midi channels.
I would like to listen to my project on my bluetooth speaker on the fly, rather than mixing down, exporting to audio format… and then direct that to my speaker. Setting my mac to connect to my speaker doesn’t work.
Or did i just answer my question in the first sentence ?

Hi,

Use a virtual instrument (for example built-in HALion Sonic SE) to generate a sound from your MIDI data.
