Unfortunately, there will always be two dedicated library versions, because ...
1) ... both players have specific file sytems; they aren't interchangeable
2) ... VI Pro hasn't the streaming power of Synchron Player
3) ... VI Pro can't handle microphone positions (which are available in Synchron libraries)I think that there still will be both players in the future. VSL mentioned that there will be more libraries for VI Pro, take Dimension Strings III as an example. Synchron Player is for users who don't have MIR Pro and don't want to deal with positioning, in my opinion.
I also don't like Synchron Player in general, the UI is horrible, but everyone has a different taste. ๐
1) No reason both players cannot understand two different file systems. Winzip understands over a hundred zip file formats.
2) Not sure what you mean by streaming power. Both players load samples into memory, neither player streams data.
3) There is no reason VIPro cant be modified to handle microphone positions, or maybe shuttled off to the MIR Pro engine. Honestly, its high time that the MIR Pro engine should be free anyway, especially considering you cant do anything with the engine itself. Yes, MIR Pro would have to be upgraded to support more than two microphone positions, however, I consider that a huge bonus, one that MIR Pro desperately needs. Compared to other convolution reverbs on the market, the lack of more than 2 microphone positions leaves MIR Pro a bit behind. This isnt to say MIR Pro isnt amazing, but it certainly needs an upgrade in number of mic placement positions.
