At first I was skeptical because of the slightly smaller keys than with the "normal" Midi keyboard. But this keyboard is sufficient. I use it on Mac with Logic Pro X, just great. In free USB port plug in and use. Enough to play along to songs of all, takes away little space and fits in ne normal, slightly larger drawer in the living room to store items, without having the same needs an extra music room. I would buy it again, works perfectly with MacBook, OS X Yosemite, and iPad iOS. 8
