It is un-listenable, certainly unplayable. As mentioned in the OP I don't think it's a tuning issue, at least not on the sax, as I've checked it more than once on different tuners. I could probably live with 2 or 3 cents difference in the sax tuning, but the sound jars on my ear, so it's more than that.

As an afterthought, is it possible to check the tuning on BIAB, and if so how?
