Hi Roberto,
just installed VEPRO on my old G5 2X2.5 w/6gigs RAM.
I use it as a slave with my new MacPro. It works great. I use it mainly for Drums(Toontrack EZDrummer) and loops Kontakt-(libraries like Evolve and Sample Logic) and Stylus RMX.
It's flawless. Even the tempo from the host is transmitted to the slave, really useful when working with loop-based material or sounds that use delays that need to stay in synch with your song's tempo.
You will need to install Leopard 10.5.8 on your G5 though. No worries, i just installed it over Tiger without a glitch and i had 6 years worth of stuff on my G5, plenty could have gone wrong i tought, but gladly i was wrong ; )
Maybe i'm pushing my luck but up till now i'm plugged through a 10/100 ethernet switch and it works great. VSL says to use a gigabit ethernet connection wich i will surely do. But it just gives you an idea of how solid VEPRO is. A fabulous piece of engineering!
Kudos VSL.
