Ah.... the old DX-7 breath controller sax! Still little around to match it..!
Samples are OK, but they are SO static. The breath controller allowed you to soft tongue, hard tongue, slur, swell, sfz, go from a purr to a growl (you could flutter tongue it and the DX-7 would flutter too!).
You get a very accurate one note with a sample. But the DX-7 allowed you to PHRASE, and, although it is an improvement, even SA2 doesn't allow you to do the stuff that old FM synth could!
