Hello, Noel,

Thanks for quick reply.

I first load midi file into BIAB (use "open" instead of "import") and play it, found there is only one track can be heard. I haven't assign any Realtracks yet.

Sorry I am fully unfamiliar with Realband..so if I import (or open) a midi file in RB, the default tracks (bass, drums, piano...etc just like BIAB) will also appear in Track view? I need these default track to generate the Intro & Interlude by loading Realtracks.

Anyway I will try RB at first, Thx again:)
