Maybe my programming wasn't good enough.
The composition and midi performance (mockup, programing) were great. People are expecting a smoother legato, or perhaps in other words a more slurred legato. I am not a programmer, so I am not sure what goes into the programming of these libraries. But in reality a performed string legato is smooth but does not contain any portamento. None at all.
My guess is that many developers are including a very small amount of portamento in their "legato" patches to fool the ear into thinking the legato is better than it really is. Also to make it seem more "human". Or perhaps the sections just aren't as carefully sampled. In a real section of 8 celli performing a legato between two notes, the timing is not going to be perfect among all 8 players, unless it is a world class orchestra. The ear hears the timing differences collectively as a sort of portamento or slurring effect.
The Synchron Strings celli sound like a very top orchestra section with only the best players who have been thoroughly rehearsed. The change from note to note is nearly perfect within the section. Without the timing differences among the 8 players, people don't hear the humanizing effect of smearing, or slurring that they associate with a string section legato.
