Despite the fact that your production is pretty nice and well done, and anyway with full respect for your opinion, I have to strongly disagree with "the problem is...".
First of all, obviously the library is not crap, it has several good things inside, and some nice well-recorded samples, but it doesn't balance the already deeply explored and technically explained weak-points, we all repeated in previous posts up to sickness. The fact of mastering the library has nothing to do with the overall disappointment:
- you are actually using in your sample long notes, with low vibrato, little or no articulation, and hyper-wet reverb. For this athmospheric sequences the library works well, but to be very honest, not so different to tons of other already existing products for easy or quick cinematic composing. (even some professional keyboards may do it).
- if it was a matter of long and tough learning-curve for the user, then anyway SyS failed the aim: VSL had the aim of creating a quick and easy fast production tool, not a complex and difficoult to manage tool. In my opinion the tool is not difficoult to use at all. Controls are streight forward and the player is pretty simple and clear. The fact you have to work-around so much with dynamics, reverb and eQ to get acceptable sound is the evidence of the weakness. The idea was the opposite, to have it flexible and good-sounding out-of-the-box.
As everybody else noticed, the problem is that if you are not writing a cinematic long notes athmospheric sequence, you will get the harsh synthy sound everytime you try to get expression and articulation in melodic and moving phrases. If you finally try to get the rich variety of articulations of a classical or romantic string orchestra, then you will just get low of ammunitions... too little and too similar articulations to get the requested sound.
We had already Dimension strings and MIR Pro to make the sound and realism to perfection: the only reason to make something new and different, was to make it easy and fast, as requested by professional producers workflow (very often it's: a master-keyboard improvvisation to get inspired, and then a fast set-up and often live-keyboard performance + rough quantization, then editing of MIDI data just for refinement).
For spending long time in programming sequences for accurate performance, Synchron Strings were not the tool, as clearly explained by the advertising, tutorials, and demos of VSL.
