I don't know, I had an apex years ago. At that time I was using two keyboards. I gave it away, because it was not steady enough and interfered with my pedals. Sound familiar? I bought a different Ultimate stand.

It was made of plastic, easy to assemble within a minute or two and made so I could sit down to play. It also included a music stand or you were able to buy adapters to add a second keyboard. I eventually got rid of everything on it but the three main pieces. These just snap together to make a wonderful stand. It looks very professional, like it was made for the keyboard sitting on it,and gives plenty of space for pedals as well. There is absolutely no keyboard bounce either. It's got to have been more than ten or fifteen years ago that I bought that Ultimate stand. It's looking a little moth eaten about now, and is cracked in one place. I'd give my eye teeth to get a new stand like it.

It was made by Ultimate, and for me it has proven to be the ultimate keyboard stand for the man who really needs to sit down when he plays.
