There's a LOT you can do with just those basic voice controls, certainly enough to rival wind controllers (although maybe not exceed them) if you are doing wind emulation.

First thing is, DON'T use the LFO vibrato. Even with some subtle programming (mod depth to LFO speed is one of my favorites), it quickly becomes obvious it isn't real.

Second thing is, you have to be anal about your legato fingering. Nothing gives away a keyboard performance more than note overlap. SA does a great job of helping this out. But for all of us that don't have SA, or you are trying to use a sound that SA doesn't cover, you STILL have to work really hard to keep your fingering clean.

My secret weapon in the battle for the best emulation is the ribbon controller. I have a Triton, a Kurzweil, and an old KX5 controller/keytar (my favorite) all with pitch strips. Use any of these, and you have a MUCH better chance of a realistic performance. For starters, forget mod wheel vibrato. Place your finger on the center spot of the ribbon and rock it around like a cello or guitar string, and presto! Natural, non periodic vibrato...

Next is the ability to jump pitch rather than bending to it. Trills, hammer-ons, hammer-offs, all of these are things impossible with a wheel. But the strip makes these a snap. Plus, because of the nature of the strip, hitting EXACTLY the perfect intonation of the jump note is impossible, it makes it more realistic, as no wind instrument (or any acoustic instrument that you finger, to be honest) ever hits the note perfectly.

Finally, you have the option of playing notes without actually hitting them on the keyboard... Once again, for those of us without SA1/2 voices, making the difference between detached and legato notes is a challenge, and monophonic mode generally makes the sounds too electronic, but the pitch strip allows you to hit notes up and down from where you are without retriggering the sample, allowing a whole phrase, or at least, sections of it to be played without moving your played note (and once again with the imprecision of intonation that real instruments show).

All of which adds inflection and realism to the line. If you have a keyboard with a touch strip on it, try hooking it in to your arranger (at home, not sure whether this is going to be a popular solution for the live giggers!) and see if you can't coax a bit more realism from your sounds...
