I have Sibelius (a 32-bit application) running on one machine, with two slaves - both currently 32-bit. One of them is running a couple of instances of VE Pro, hosting Gigastudio GVI, which is of course (and will forever be) 32-bit.
But the other slave is hosting a number of instances of VE Pro, all loaded to the gills with VSL instruments. This machine is straining at the 4Gb memory limit, and I would love to upgrade it to 64-bit Windows 7 and give it a huge amount of memory.
So the question is: would this work with my 32-bit Sibelius host, running 32-bit VE Pro client VSTis? Or does the entire chain of VE Pro clients and servers have to have the same number of bits?!
