PG Music Home Forums PG Music Product Forums Band-in-a-Box for Windows ACCESS VIOLATION ERROR: My investigation and a solution I discovered

• Bass: #538 – Bass, Acoustic Pop Sw 190
  
• Piano: MIDI
  
• Drums: MIDI
  
• Guitar: #374 – Guitar, Acoustic, Strumming Hank Sw 190
  
• Strings: MIDI
  
• Melody: as per demo file
  
• Soloist: #818 – Guitar, Electric, Soloist Country Classic Swing Sw 190

• Load song demo for Burkes.STY and return to the chord sheet window
  
• Add Reatrack instruments (as above) to Bass and Guitar.
  
• Mute Melody.
  
• Use “Soloist” button to activate soloist.
  
• Select Realtrack #818 and generate solo in “Middle chorus only”. (When I play the song now, it sounds fine.)
  
• Save the song with some temporary, new name. (On my computer, a message pops up and tells me that the Soloist has been locked and that the Realtrack solo has been saved... etc. At this stage, if I unfreeze the Soloist and save the song again, the Soloist will freeze on saving. )
  
• Save song with the frozen Soloist.
  
• Exit BIAB.
  
• Restart BIAB and open song.
  
• When I try and generate the song, I get the error Access violation at address 00405F74 in module bbw.exe. Read of address 00000004 at 00405F74
  
• Click OK.
  
• Now when I try to generate the song, I get a pop-up message saying Playback generation is already in progress. Load another song if this message persists.
  
• If the above does not cause the problem for you, try un-checking "Soloist" under the "Freeze" icon and then save.

• Load a MIDI-only song, generate it and let it play for a few bars to check that it works. Exit BIAB.

• Start BIAB and load the problem song
  
• Right-click on “Soloist” on the menu bar and “Erase” the Soloist track.
  
• Save the song. At this stage, the song will still not generate for me
  
• Exit BIAB and restart it (after saving the song with the Soloist data erased).
  
• The song now plays for me.

• Seems like my problem is caused by the Soloist's freezing when being saved and then reloaded after BIAB has been restarted.
  
• Unfreezing the Soloist track, erasing all data from it, saving the song and restarting BIAB allows me to load the song again without incident.

I'd be interested to know if others can produce this error or if it is mine alone! Hope this information helps.

• Opened BIAB as the first and only program after startup (other than my antivirus software which has always been on)
  
• Turned off VSTi
  
• Restarted BIAB
  
• Regenerated the Soloist
  
• Unchecked the "Soloist" under the by right-clicking on the "Freeze" icon. Saved the file using "Save+" I was annoyed that the problem file worked, today, I repeated this procedure of unchecking and saving numerous times!
  
• Then when exiting BIAB, I had four access errors; one after the other popping up in my screen.
  
• I restarted BIAB, opened the file again, and it played! Now I'm really puzzled.
