We haven't seen an issue like this, but will look into it. It would help if you had an example song that does it, since then we would know what tempo, what style etc.
Email a song to beta@pgmusic.com
Also, does it happen if you render, or only with live playback? and is it that the realtracks are synced to themselves but not to real drums?


Have Fun!
