Default Instrument for Midifile import

New user here - how do I change the default instrument that sets up whenever I import a midifile? Right now I get Halion SE that works fine. What I want to get is Halion 6 that I recently purchased. I can open a track with it but need to open multiple versions to get more than one instrument - whereas Halion SE will allow up to 16 instuments in one - Help? :open_mouth:

Thanks in advance

Load Halion 6, then select all MIDI tracks. In the MIDI output section of the Inspector, hold Alt + Shift and then select Halion 6 as the MIDI output:

This will change the output of all selected MIDI tracks to Halion 6.
