Quantum-leap? It's a necessity foremost. Multiple mixable perspectives is not something new. If you're looking for a "quantum-leap" in that regard, Hans Zimmer Strings has way more acoustic perspectives than Synchron Strings.
Sorry, but I fear you misunderstood Hans Zimmer Strings a bit. HZS provide You per section (not 9 different Mikrophonepositions) but as far as I understood it only the choice between 1 (Basses), 2 (Violas) up to 5 different recording positions of the Sections. Yes each seem to be recorded with a different amount of Microphones. But you do not have (as far as I know) for each microphoneposition seperate Samples as you have in Synchron Strings.
If you load for instance the Patch "60 Cellos all in one" you do not load for each of "26" used Microphones a complete sets of all available patches but as far as I understand just one Sampleset for each of the up to five 'recordingpositions' of the Cellos . (But of course not for each of the 26 used Microphones to record them.)
In Synchron Strings you definitly can load and mix based on complete seperate samplesets for each of the 8 different available "Microphone-positions". But you are right to have multiple Microphonepositions might be developed by VSL more extensive than other Orchestra libraries with usually 3-5 (sometimes 7) Microphone-positions available for the mix. But this allone might not be regarded as the "Quantum Leap"
The "Quantum Leap" is imho that VSL allow at the same time in an absolutly unprecedented way to switch or/and blend through up to 8 "dimensions of articulations" combined with the fexibility the 8 Microphonepositions.
And the whole project and Concept is not aimed to raise the custome-rattention with extreme but musicaly pretty useless and scarcly reasonable Buzzwordings but based on very realisitic orchestral situation and Mixing setup.
Regarding the fact, that HZS make with all their patches and recording-positions not more than a third of the sampleamount of Synchronstrings I (Which is just the First Volume of the complete Strings to come) it appears to me a bit to courageuos to compare something like the "Buy-me-because I-am-XXL Jumbo-size super exagerated Hans Zimmer Strings" with a serious and in its variety and organisation tremendous powerfull Orchestral project like the Synchron-series.
