I keep buying it becuase I like the style (not too formal) and the free software is great, I think. Looking forward to the upcoming 'Freeware' special - loved the one last year. Indeed, I am thinking of using free plug-in's exclusively from now on because the quality of the CM ones (and other free stuff) is so good. I could then focus on saving for a Lemur to control it all
There does seem to be a 'cycle' of articles but I've noticed this with other magazines too.
For software coverage, in the UK you have a choice of CM, Future Music, Sound On Sound and Music Tech. Personally, I think CM is by far the best in terms of software techniques, although SOS has better reviews and better articles/interviews (SOS is better researched and more thorough overall.) FM has had some great DVD interviews. CM has these too but they always focus on the same styles of music and aren't as interesting as the FM ones. Music Tech I just can't get into, but I did like their Live special a couple of months back.
The only overseas magazine I can comment on in comparison is Electronic Musician in the U.S. This is roughly equivalent to CM but I don't think it's as good. I won a subscription to it and fair play they shipped it across to the UK each month, but without the coverdisc (so I don't know what the content is like.) I think EM is a lot cheaper than CM but it was also a lot thinner, had more adverts, and the articles/reviews were less in-depth.
