Donny, not a chance in hell!! But I will buy the first Yamaha product that puts SA voices in a rack..... I must say I disagree with your assessment of them - as a horn player, I have to admit that the SA Sax is the first thing I have EVER heard that comes close to a real sax's playing style, with legato and staccato actually sounding like the real thing.
For 20 years, since the introduction of affordable sampling, I have been asking fruitlessly for the Hammond organ percussion type of triggering for synths and samplers...... Polyphonic voices, with a single-trigger, polyphonic layer for the start of phrases. This is what STILL makes B3's so expressive. You can emphasize the start of legato passages by lifting your fingers for a split second, get the percussion voices to emphasize the start of the phrase and continue playing legato with no further sound from the 'attack' sound. Perfect.......
It's only taken them 20 years to start to realize how much more expressive this makes sampled voices, especially. 8)
This triggering system, combined with a pitch-ribbon for bends and trills can get you spectacularly close to real horn phrasing.........
