Iv'e only skimmed the posts,and the OP's suggestions seem good,BUT-WOW This has been SO Much Easier than I EVER would have believed!
Firstly I use Chrome exclusively,as the downloading info while your downloading multiple files is very good SO,I just dwnldd the FIRST 2 info files,ALL the X2 .exe's[4 of them] + additional content,NO loops/one shots yet,SO the FIRST 6 files in your account download area,and number 12-additional content.
This all got done in about 2hrs,then I just opened the FIRST.exe[X2 .exe-not the info/PDF]and everything unpacked,I had already written my serials/Reg no.s last week,and presto,all my plugins,third party synths Everything,was just too easy.
The only mods,I have done is copy my X1 pro channel presets into X2's,as well as project templates,and some FX chain presets,and obviously I didn't copy the ones that are already in X2.
First impression is WOW,all my hassles of pro channel/fx chain presets opening to the wrong page....FIXED,yay!,and within minutes of the unpack,I was inserting Breverb/R-Mix,and playing projects back just as I would have yesterday,WITHOUT having to re-install ANY Pro Channel modules,or any plugins...simply amazing,excellent job Cakewalk,Easily the best most seamless install of ANYTHING Iv'e EVER HAD!
Thank you Cakewalk,X2 seems really astoundingly cool already!
