Yeah, well one step at a time man... take it easy, and it will come to you. You don't have to be diving into the deep end and getting into trouble.
Tell me, what sort of stuff are you doing? The reason I ask is that there are so many ways of making music nowadays.
Are you "real" instruments person? That is, will you be recording mainly audio tracks in Sonar? Guitar, bass, drums, keys etc?
Or will you create music using the many available soft synths?
I did some homework though, and if you've got a UX1 then you'll be recording guitars and probably vocals? And for drums you may use soft synths like Studio Instruments Drums perhaps?
I'm just trying to get an idea of where to start helping you.
I'm off to bed now though, I'm in the UK and I'm up early for work tomorrow.
cheers for now
