Rewire 64

With Sonar X1d,

Is anyone know if I can link Sibelius 7 with Sonar X1d using Rewire 64 ?

Even if Sibelius 7 is a x64 application and even if I run it in x64 mode under Windows 7 x64, is Sibelius 7 is Rewire 64 compatible ?

or only Rewire x32 compatible ?

Does I need to add something on my system to use Rewire 64 ?

I saw that Sonar X1d support Rewire 64. But is there many music applications that support Rewire 64 ?

Thanks,

Francois, Montreal
