The thing is, Bill, if the sample is sampled with vibrato on it, that's it... you can't take it off. Let's not get confused with sounds sampled 'straight', and then an LFO is used to make the vibrato (which you CAN edit).

Real instruments' vibratos are FAR more complex than a simple LFO on the pitch. Volume, timbre AND phase are ALL modulated in a 'real' vibrato, much of it under physical control of the player. It is different from player to player (you can often tell who you are listening to solely by the way they use their vibrato), and from song to song (vibrato is often altered depending on tempo).

But sampling them has it's Achilles heel... First of all, if you don't sample each and every note separately, they speed up when the sample is transposed (or slow down), you can't control when they come in, and this changes as it is transposed, too, and you can do nothing about the depth and speed. This is all made less important if you have a GIGA sized set of samples, but on the regular ROM of most arrangers, there's just not enough space for all that. Would that you COULD take sampled vibrato off when needed, but it's just not doable.

I prefer samples without vibrato, most of the time, and use a pitch strip to induce a real vibrato (one that isn't mechanically regular, like an LFO) for the best sound, if I can. But I LOVE vibrato'd samples as layers for straight ones (or two different vibrato'd samples together). It gives a great thick sound..
