I just purchased this keyboard, after having the MX88, which has 88 keys, so I knew the great sounds it has. I use it for band use. Had had Yamaha keyboards for over 45 years. I also own a digital piano by Yamaha. This keyboard has every conceivable sound anybody could want or need. Can't believe how light it is. Storing up to 128 sounds is virtually a 2 or 3 step process. Great for just playing by myself, using the already stored "performances" (combination of sounds). The price is good, and of course it is dependable. I am very happy with it.
