Hi There,
I have had a few similar issues with dissonant chords sounding. I reported one instance of it (in the pop organ realtrack) to PG Tech support and they advised me that it was a problem with the realtrack file itself. Some similar issues were fixed with other realtracks within the 2009.5 realtracks delivery and a bunch more were fixed in a later update (there is a sticky message regarding this update at the top of this forum).

The problem is a little random. Sometimes a particular chord sequence will work perfectly in one part of the song but will sound discordant in another part of the song. I have used this randomness to effect a tactical solution by doing some cut and paste of the generated WAV file within my DAW (copying the OK instances and pasting them in instead of the discordant ones).

I think that there are still potentially a few unfixed realtracks files (to my ears some of the 'dreamy guitar' realtracks seem to have this problem but there may also be others).

Probably worth posting a copy of your BIAB song file to PG Tech support and seeing if they confirm that it is the same issue. (although I would make sure that you have downloaded the latest realtrack updates first and see if this cures the problem).

Regards, Aubrey

P.S. - If everything is sounding permanetly discordant then Mac's advise re. the soundcard sample rate sounds like a good bet.

If I hadn't seen such riches I could live with being poor.
