Question: Will this hold a Yamaha Stagepas 600i mixer or is the opening too wide?
Document: Just what the doctor ordered. Not suggesting putting this in your home gym. However what its designed for works great. Holds Yamaha 88 key keyboard perfect even with me pounding on it. Folds easy and great leg room,, and easy storage.
If you want a heavy solid stand for your keyboard or mixer, this is it.Its made of steel not aluminum. One problem was that the stand comes with no bumpers or pads on the top so your keyboard will slide around until you buy some and install them yourself.
The stand puts my Yamaha P-105 awfully high for me, at 5'2&#34;. I expected to be able to sit in a chair and reach the keys. I adjusted the stand up even higher to work with a medium height counter stool for my 6' tall friends, and that worked for them. The stand  does support the piano and you get leg room. If you want to stand and play, it would be fine.
Very sturdy and I can get my legs under it just like sitting at a table.
This is one great heavy duty stand. Perfect for my 65 pound 77 key electronic keyboard. I give it 5+ stars.
The best stand I've ever seen! Even thought I've only personally seen two kinds.
Solid keyboard stand for serious players! Ditch that X stand and move up to a table type stand. Your keys will not move and your playing will improve immediately. And your pedals will be in the correct position, under the keyboard and not to the side. If you have always used an X stand, give this a try and you will never go back.Height and width adjustable, good for mixers too. Table legs also have levelers in the feet, uneven floors are no problem!
Now I feel that I am playing a piano, the way that a piano is so still on the floor. and I feel much more comfortable playing the keyboard, A big , big difference.. The stand feels sturdy , and firm, besides it has a nice design.
Love it!
If I played a lot, which I do not, I would look for another solution. I would love to make this work. If anybody has another suggestion, please let me know.
Answer: I cut a half inch piece of plywood and laid it across the opening so my keyboard would fit.
