I subscribe to the print version of Keyboard Magazine and find many helpful articles on playing keyboards, reviews of new keyboards and other related equipment but most of all the very interesting articles and interviews about and with a variety of artists. Plus there are Links to sound examples and demos at their web site. So for me well worth the the $12/yr.
I also have free Digital subscriptions to Pro Audio, Mix Magazine and Electronic Musician. Each has interesting and topical articles and reviews.
There is an evolving world of music, technique and equipment out there as well as a myriad of artists with something to contribute.
These publications are a good way to keep informed.
