I can not honestly say that I have made the full move to Sonar as yet but will be giving it some serious thought over the next few weeks as I learn how to use it.
Over the years I have learned the basics of many audio softwares out there. This has been because 1) I have/still work in the music industry sometimes, 2) I like to learn new things, 3) why not?
Each has their good and bad points. The last one I was/still using is Logic pro 8 what I must admit has I have using Logic the longest. I have found Reason has the best user freindly softsyths. Ableton has a great timestreching thing for audio and a few other tricks but of course this is my own opinion. I haven't tried every music making software out there but I do hope that there will be one that combines all the best bits from all of them out ther and make into one.
So far the only bad point I have found with Sonar is It aint easy to use without first reading or watching a video on how to use it, this can be a good thing as well as a bad thing, also I can't find any short cuts for copy, paste and cut. I have been reading about Sonar and keep seeing things about bugs, haven't come accross any as yet.
I will say that I love the sound I get from Sonar (the brass and strings instruments are excilent for sounds that come in the standard package) and when I installed my copy it worked straight away, something that doesn't really seem to happen I noticed in recent years, always something needs tweaking before you can start.
I am hoping that I can find a DAW that will have and do everything I want it to without having to rewire or import/export.
One otherthing what I like so-far with Sonar is It can use instruments from other software like cubase, wish it was possible to use some of the bits in Reason in Sonar aswell. Also Cakewlk has the best forum I have ever used.
Update- Taday I was playing around with Sonar and i must say dispite the fact I haven't really done anything on it I am begining to love it very much
