Hi BitFlipper. If indeed you are the same as the BitFlipper on SONAR, we are very fortunate to have you here, with your audio engineering knowledge. Welcome. I'm 'Riojazz' on the SONAR forum (much more active here).

Of course, Welcome even if you aren't the same BitFlipper!

I concur with Mike, the presence of a chord after the 'end' is not enough to crash BIAB with any of my songs. I actually do this a lot, since I might try out many alternative chords as I compose a song, and I store the various ideas in the gray area beyond the 'end' of the song.

I have heard of corrupted songs before, but I do not recall one ever becoming unusable. Anyone else?

BitFlipper, just looking for more clues:

Did you by any chance use the Freeze function on any Real Tracks?

Does it make a difference if you set UAC in Windows 7 to the minimum?

What are you using for MIDI Output? DXi? External synth?

And one tip:

Whenever BIAB starts acting as you know it should not, there is a user settings file (/BB/intrface.bbw) that apparently can get corrupted. Opt, Return to Factory Settings will restore everything and sometimes solve those nagging problems. You can save your settings first, or else it will prompt you to do so (assuming you have BIAB version 2010).
