Summary: It's simple, without any ado and meets my expectations perfectly. There are keyboards that has more functions, and I already had one of those before I bought this - the KeyRig was worth buying just because it's so simple. And no software!
Summary: I got this keyboard late last year and have been very impressed with it. I'm currently using it as a midi controller for garageband on my mac and it works great it responds well and is pressure sensitive so the harder you play a note the louder it is.
Summary: The M-Audio KeyRig 49 is a great tool for the musician looking to add a midi controller through the usb port. I am using a 3 year old MacBook Pro and have done lots of recording of guitars and vocals in Logic.
Summary: I purchased this keyboard for use with Finale 2010 on my Mac. It works as I expected and I have had no problems so far. As others have noted, the keys are not weighted, but for note entry it works as I would like. I also like that it is a half size keyboard so it is easy to store.
Summary: All you have to do is plug it in to your computer's USB port, turn it on, and run SimplePiano, or any other similar free Windows program that takes input from a MIDI device and outputs it to the MIDI sound output that comes with Windows, and start playing.
Summary: This keyboard is perfect for basic MIDI entry, which is all I need - it's compact, light, portable, and USB powered. The only problem is, there is no gig bag that I can find that fits a keyboard like this.
Summary: Though it does have a bit of a toy-ish feel, this serves my needs perfectly. If you are someone who is looking to perfect their piano playing, I don't highly recommend it, because it is not the greatest reproduction of a real piano.
Summary: This keyboard is priced at very much less than I have previously seen for this type of product. It fits in front of my iMac screen quite neatly matching the finish even, and works at least as well as you would expect in this price range One reviewer said that this keyboard did not work with Sibelius...
