Hi all. I do not play the horn, but have a Q I was hoping someone would be kind enough to answer.

I am a composer, who like most others, has to rely primarily on samples to compose and make a living. It's unfortunate, but that's the way of the world. I have a sample library which has a solo horn patch, a 2FH patch, and 6FH patch. I am noticing something strange in the solo patch (one horn player, obviously). There is a quiver of sorts in almost all of the notes. It's to varying degrees, but definitely noticeable.

Here is a short, 2.4 MB file illustrating what I am talking about.

Is this type of quiver normal? This is from one of the biggest sample library devs around recorded in a major studio - and although I have no idea who the musicians were, I have to assume they hired accomplished players, as opposed to, say, a HS student.

Any thoughts will be appreciated. Thanks in advance.

This type of quiver is NOT normal.
This sounds like someone who doesn't play regularly. The embouchure is not toned, the air is used inefficiently. Not a good quality sound at all.
This is a poor, poor sampling.

It is absolutely normal.
