If you want solo sounds to be as effective as the real thing, you have to give up your left hand to the bender. Plain and simple.
Scoops, natural (non LFO or sampled) vibrato, big bend ups and downs (that's why a pedal doesn't work), timbral changes... All these things happen with a real player from note to note (and most of the really juicy stuff occurs at chord change boundaries, so there goes your LH). Unless you are willing to go to SMF's, I'm afraid that convincing solos will always be at least one step removed from reality...
I always prefer a non-vibrato sound for solos, as the speed of the vibrato changes depending on the tempo of the music (can't sample that!) and the emotional content of the line. A pitch strip allows you to do VERY convincing vibrato, as well as trills and note jumps without re-triggering the envelopes and sample starts. Trouble is, no arrangers have them yet.... I would have thought at least Korg would have (being on their WS's).
But analyze real players carefully, and you start to realize just how much of whet they play has at least SOME pitch variation. Sampled vibrato, even if done for every note, won't get you that. It's a nice dream, but it won't satisfy you unless you finally give up on that arranger chord cuing, IMO.

. So true. Using a pedal to bend does get you a little closer, and even though I can only set it for up or down, it does let me bend at the chord changes at least in one direction.  I don't mind missing a few bends here and there  ...sometimes these can be overdone, and make things sound less realistic, especially if the voice you are working with has other issues. One of these issues that Yamaha SA/SA2 voices addressed was unrealistic attacks. Now, using SA technology, and depending on if you play legato or not, the note will re-attack or play smoothly...that always frustrated me with the older style voices...even though they were great samples, the multiple attacks always made it sound so poor. SA Guitars also give you pitch bending if played with the recommended technique...very cool, and also respond nicely to legato play....and you don't need to lose the left hand. I still prefer the immediacy and flexibility of LH chords and RH melody, and even though SMF can be fairly pliant when using markers and other tricks, I just find the former more satisfying and more fun too.

All good points...but you kind of missed my point here.
Go to your arranger. pick a flute, oboe, violin, sax, trumpet, english horn, etc...etc..solo orch. voices, play only that sound SLOWLEY up and down the keybed...(try different velocities for different passes...like you would on a slow ballad, be sure to HOLD that note for a while...listen to the vibrato and timbre carefully note - note. Not all voices will have problems (seems like the ones I really like seem do)
You will find that things go well ...then OOPS, what the hell is that...it's a different timbre and/or a faster or slower vibrato ( by a lot). That's the issue. The other night I was playing stranger on the shore for my wife, using the PA's tenor sax exp 1..all of a sudden my wife says 'What was that sound? it sounded like a duck honking, compared to the other notes'
A little variance is fine it adds to the realism, but not when it is a significant change. Who do they have QC test these things....the janitor?
If you play fast country or rock...you will probably never care about this.
Oh by the way...the Motif and the Korg M3 have some of the same problems. My Kurzweil has VERY little. But, they don't make arrangers.
So the only answer today is 1) get great samples and make your own complete new sound 2) use a PC with top quality VSTi sample player (and spend big $$).
It's just sloppyness...you take a beautiful sax on the PA2...very nice except one or two samples they used do not match the others in timbre or vibrato..ruins the performane. But other Sax's are OK. Same thing I found on the T2. They sample the sounds with vibrato to make the programming easier (less work). But that is a mistake. Yes, some say it is a more realistic vibrato if it is sampled...but if the speed is screwed up ...who cares! Sometimes it's just they copy a sound from a previous keyboard and the problem right along with it.
When I play the Ketron Audya in a couple weeks we will see how it rates in this area.
It will be interesting to see how they did.
For now...I just don't use some of the sounds with issues...and some of those I like in general!

Leeboy... it's not sloppiness. It just reality creeping in. What you are hearing is samples being stretched up or down to cover more than one note. This makes any periodic aspect of the sound (vibrato, tonging, attacks, decays, etc.) either speed up or slow down as the sample is transposed, and any timbral characteristic, and formants get brighter or duller as the sample is transposed, again. Reality is that at today's cost for ROM, it would be too expensive to have enough ROM so that this NEVER happens. Something on the order of twenty to one hundred times as much ROM would be needed to do this. Look at the size of GIGA samples that do this... each one is close to GB's in size. This is no problem for GIGA Sampler, as it streams off the hard drive and doesn't actually use much RAM, but in a non computer keyboard, well, the top limit for current ROM is maybe 200-300MB or so. For the entire soundset. So you have to be realistic, I'm afraid. As for the Kurzweil... sorry, I've got one of those. PLENTY of abrupt sample boundaries in that (I have the K2500S). They, however, don't suffer from the vibrato thing as much as many modern keyboards, because the basic ROM sounds were sampled before they HAD enough room for vibratoed samples (they take up MUCH more ROM), and tend to use LFO's for most of the vibrato, along with some clever programming, like modulating the LFO speed from the wheel amount or velocity. In fact, I wrote an article here some time ago showing how these sample boundaries can be used for great effect to get MORE timbral variety out of the instrument. http://www.synthzone.com/ubbs/Forum37/HTML/017002.html Enjoy.
