When I went to the download page for X2, there were a couple things I didn't expect. I don't want to do any extra installs that I don't need. If I already had X1, do I need to install the "03_Loops_And_One_Shots" or are these the same that were in my X1 already... the same goes for "04_Dimension_Pro_1.5_Expansion_Packs.zip" I know about the extra String Expansion sets, but didn't expect these... different from X1? Anybody install these? Thanks!

They are not the same though there may be duplicates for loops and one shots. If you have Dim Pro 1.5 there is no need to reinstall it.  I can't say about the expansion packs for DP.
The strings is up to you if you don't already have it now is the time to get it.

I too have X1 Expaneded and I am DLing everything I wont install it all its not necessary.

Yeah, I know I don't have to download Dimension Pro 1.5, but I'm not sure about the "Expansion Packs" (not the strings, I know about those). The last expansion pack I got for Dim Pro was the Bass pack that came with X1 and don't want to go through the whole process of installing something I already have. Thanks for the info about the Loops and One Shots... I guess I will download and install those. Thanks again.
