I know that Synchron instruments are really great sounding and what many people will want to use, but I have to make this observation -
One of the most remarkable things about VSL has always been how every single recording ever done - out of millions literally - was compatible with the others. The First Edition instruments could be used with the latest ones the same exact way. Even the different string libraries - like Dimension, Orchestral, Appassionata, etc. - all can be used alone, but also blended to create a "meta-library" of string sounds that can have mind-boggling diversity as shown by all the demos and user compositions that combine sounds in new ways.
I started thinking about this because of FX Strings. The FX strings have been created FOR SYNCHRON ONLY. If they were for Orchestral Strings recorded on the Silent Stage then they could be used in any VSL recording. So you could even use them with Synchron by using the MIR Synchron impulses. But the reverse - going from a Synchron to non-Synchron - does not work since the reverb is baked in.
I am now thinking the executive decision has been made - no more non-Synchron recordings. All the instruments previously sampled are "Legacy" sounds. Is that true? That shouldn't happen because what made the company an industry leader was the total compatibility of all instruments and systems that is has always had.
