Playing and Editing Midi File

Could some tell me the correct way to import a midi file . I want to be able to see all 16 channels and edit them . I am sure i was able to do this a few years ago but i cant remember how i did it.

I can import the midi file using Open Special / Midi file.

The complete file contents shows up in a track called Bass 2 in he mixer window . Before i loaded the file this track wall called Melody.

I get the chords sheet and can play the file with all the tracks included

How do i get the the 16 channels out into there own tracks in the mixer window so i can edit them ?

I am running 2024 pro version.

Thanks
