Just as you so nicely presented, I get the same results as you did. I found that playing a midi style and exiting BiaB then re-entering it will stop the access violation problem. I did not figure out your last part on removing the soloist and re-saving the problem song (never thought to try that). But, as you stated, the problem piece will work after doing that and restarting BiaB. Thanks a million. Now PGMusic needs to work on a solution that will still allow us to save a soloist track with a RealTrack instrument playing, but for now we can at least re-generate the soloist part (though different) each time we want to play the song. Of course, the other way around that problem is to use the DAW plugin and ship it over to RealBand or DAW of your choice and then be able to keep that awesome solo you just got from the RealTrack Blues Trumpet Player. :-)

Thanks for the info!
