I'm on BIAB 2013 build 366, running on Windows 7 (64-bit).

I use realtracks / realdrums and realtracks for solos and use BIAB to generate all my backing tracks.

I freeze all tracks and then render finished songs to audio track (play / render). This is because I load them on a laptop when playing on stage and this seems to work best - even though the laptop is a powerful beast I have had BIAB lock up / stutter / go weird, if I don't have everything ready in advance. It also means I know exactly what is coming and have no timing issues.

I notice that when rendering this way the drums track (I use realdrums) changes from green to yellow after the render and says that I am using a MIDI kit - doesn't sound like it to me, just seems to be a bug in the display?
