I load a midi song in biab and everything is on the same channel.

I load it into realband and it seperates the tracks.

I save as type 1 midi and reload it into biab everything is still on the same track.

How can I seperate these channels into different tracks for biab.

I need to use melody in tc helicon but cannot seperate the channels into tracks for biab.

Does anybody know how to seperate the channels into tracks for biab?
