Thanx for all the answers.
Cyril, I can wait a week or two. Even more. I'm not gonna get it inmediately.
As far as the painful threads about Mac vs PC I'm really tired of that. Macs are great. PCs too. Period. As noldar12 says, it's amatter of taste. I've been using Mac for 20 years and Logic since vers. 3 or 4 (don't remember) and am too old to learn a new DAW. Probably I'll stick with Mac for sequencing and getting a PC as slave since Macs prices are way high. Also the fact of many companies say their products run better in PCs is an added bonus.
Regarding my needs they are different in each project. I don't use Vienna Instruments. Just Kontakt libreries, PLAY and some Omnisphere, as well as EXS Instruments. I can use a very small template of 5 to 10 instruments or go for a bigger one with 40 to 50. It really depends. Not using 5.1 or 7.1 but mixing in stereo. At some point I'd love to use MIR Pro or MIR Pro SE when it comes available.
Thanks again :)
