Hi Steffen,
What do you mean by SC?...Are you asking if my system will run an entire orchestra at once?...and as far as RAM usage is concerned...to my knowledge, the RAM being used to run samples is inside the unit running VI, not the external hard drive. I know that there's a small buffer in the Ext. HD, but I'm pretty sure that the master sequencer will be pulling the load...I was trying to use another library in August from 1 external hard drive, and since I've spaced the library out amongst these drives, I haven't gotten any Disk Too Slow error messages...(this isn't to say that my system is bulletproof now, because I"m STILL spending time setting it up)...but, I've got a G5 1.8 running my host (within which I'm loading VI instances) program with 4 gigs of RAM...so, once I start running out of RAM for that program, I'll just load another instance of the host, allowing me to access the remainder of my 4 gigs. Unless I'm wrong about how VI streams samples, I'm thinking that the orchestra will run fine with my setup...I may run into a wall with the woowinds and brass, but we'll see.
Another thing to keep in mind, I'm running only sounds on my 1.8 G5...it is only generating sounds, just like a GigaStudio would. I've got another G5 (2.7 dual) which I'm running Logic and other programs...although, I'm thinking about switching the systems around, and generate MIDI from my 1.8 single and running sounds on the 2.7.
