Noel,
You are correct, it is interpolating and DAW will do the trick.
However, if it is a specific advertised "feature" that does not work, it should be fixed. No excuses.

I got very frustrated yesterday, because I thought it related to the other, EOSerror that I had with BIAB and it took quite a bit of my time to figure out what was actually going on. So instead of doing some music stuff, I was testing things.

What got me confused is that rendered (24bit) files had some "weight" (8+ meg) but no player or DAW would play them.

P.S. Going back to philosophy of "features". I rather see 5 big things done the right way, than see 50 features that need significant ironing and beta testing.
