Got it. The trick is to not run Falcon simulteous with Pro Tools, like good old Rebirth and Reason (thatś where I went wrong). Instead you can just select Falcon in the instruments section in the insert-list in the mix window. as a plugin.

Each instance of Falcon (on each different PT instrument track) should have its part set on Master output. To my findings so far there's no using other Falcon outputs in this setup. Additional outputs apart from the Master fader are only to be used when Falcon runs standalone.
