Yeah it's been a weird process coming to terms with all the possibilities.
Personally, I took advantage of a BF sale and topped my Reason license up to 10, as I was on 7 and a lot has happened up in Sweden in the past couple of years. Not a lot of people seem to talk about it much around here but it's a remarkable product in many ways, very creative and fun and deeper than most seem to realize.
Then I plopped down a whopping $29 for Mixbus, I figured hey, worth a look at that price, see if the magic fairy dust its enthusiasts go on about is something that will work for me.
Then I installed tested a lot of other things. Studio One, Mixcraft, Samplitude... I liked them all in various ways, but none of them was "clicking" for me in the way that others have described above. Studio One was probably closest, but I kind of couldn't quite decide between that and the greater depth (and apparent complexity) of Samplitude.
Oh, and I poked my nose around Live a bit more - I have a license for 9 Suite, which I hardly use at all, long story, I know it's a remarkable program but I somehow can't imagine using it as a main workhorse.
Then I updated and fired up my Reaper demo that I've had installed for years, occasionally kicked the tires a bit but never actually did any work in, and my mind was quite blown. Reaper is *insane*. I think it's as deep as anything out there, deeper than most when you include all the add-ons available, mostly for free... plus, the efficiency and stability of the code is unbelievable, and the pace of development simply breathtaking. And the community seems very cool, on par with this one if a bit nerdier... It didn't take me long to realize that it's the one for me to gradually move towards. License bought, decision made.
So now like Bapu (and a few others around these parts) I have an embarrassmet of riches: SPlat, Reaper, Reason, Live, Mixbus... I think that will be enough for me for the foreseeable future! The sales on S1 and Samp (and Cubase, and DP!) are very tempting but so is not having to explain to my wife why I need 7 (or 8 or 9!) DAWs when I already have 5 perfectly good ones...
So I upgraded my Toneboosters to BusTools3 instead - that'll cover me for some of the Cake plugs that don't port over (Adaptive, couple of others; I never used the Nomad stuff much anyway). I think otherwise I'm pretty covered.
