I love this little keyboard. I use it in Garage Band all the time. It just makes the keyboard functions so much easier. What I wish that could be done is modifying the Mod wheel for use in the B3 organ mode to control the Leslie rotor speed. I also wish i would have splurged a little on the 49-note keyboard instead of the 2 octave. I actually like using my iPad as an instrument, so the 25 note is a little prohibitive as far as actual music production is concerned. It's easy to travel with and super-easy to use. It's literally plug and play. Very versatile. I will be getting the 49-note keyboard in the near future, though.
It is basic and works with GarageBand. All I had to do is plug it in and choose the instrument and create music. Nothing fancy about it and it does the job. What is nice is that it has a USB plugin which will work with a Mac based computer.
