Hello Scottyee--- I have been doing some checking on these.... I like you use mostly piano and the cost for the piano sample is 60 eur or 86 usd.... The guy said for a T4 he would make the sample about 100mb... Do you need more memory than what comes with the T4 to load this much? Not sure if I want to try it but I am always looking for that perfect piano..... Drive myself crazy .... Ron
