I bought this bag for my Korg PA800 and I am actually pretty happy with it. The keyboard fits good and it the pockets were good for storing the cables needed. The music stand would also fit in the keyboard area.
I think that the quality of the bag is also pretty good. It is perfect that it is water proof as well.
I wish that it would be a little bit easier to carry the keyboard using the handles, as it feels like the keyboard almost reaches the ground when carrying it. Sometimes, it touches the ground when it bounces, but I guess I should take it a little bit easier.
Overall, it is a good product!
