I bought this keyboard about a year ago because i just got started in music writing and need a controller. It usually costs $250 but I was about to buy it for $150 on ebay, used. When I received it in the mail and tried it, I loved it! \
It has such a good feel to the knobs, especially the pitch and mod wheels. There is a USB connection as well as MIDI in and out, and they all work great. You can customize what knob or wheel does what, then save it onto the Axiom; it will remember it even if you unplug it. You can change the velocity sensitivity and pretty much anything you can imagine you can change. It works great with all the DAW I used it with, which is FL Studio, Mixcraft, Garageband, Cubase, and Ableton.
If you are looking for a good keyboard controller that's portable and can go anywhere, get this one!
