I do have synth anthology II (One thing I've always been confused by is Falcon browser. I don't seem to have a way to separate the Vintage Vault stuff from my other libraries. I own some other things, like Whoosh, but I don't recognize things as being part of Vintage Vault.)
UVI Quadra Traveler is
World 2 is like 40 GB. It may not be fun, but it may serve to help add small touches where they might be really great in a piece. On the other hand you make a good point, sequencers can be helpful as well. I am not sure which to get but I am sure you're right - they are very different in their capabilities.
I began reading this thread to choose how to use the voucher, but was also hoping to fill out my coverage of exotic and world instruments. Realizing some of the limitations with World Suite 2 is why I started thinking that instead I may possibly just cover some other missing links (for example Psytrance (Hypnotic Drive) - that expansion could be helpful in my case). But I still don't have a good decision ready to go :D
I don't like that when I go to MY UVI, my orders and licenses aren't visible on a per-product basis. ( Not that big a deal - I just wish I kept better track I am having a hard time figuring out if Wave Runner is part of Synth Anthology).
And because I can't separate Vintage Vault 4 from my other libraries, I feel like I have no idea what I own right now :D
