I am currently using this for holding Alesis Andromeda, Moog Subsequent and some sequencers and it works great for them. I will be having Moog Voyager soon, but due to depth / height issues I'm not sure if I can use it in this stand.
First I put the stand together I thought none of my stuff fits in it, but with very flexible adjustments many things are possible. The additional support from the back can't be reached by the longest arms though if they have angle which I need to have in order to see at least some of the params of A6.
The good:
- it's quite easy to setup, modify, extend and looks great
- it's very sturdy when correctly build
The bad:
- You should really be able to adjust how deep the shelves are. For example for this exact model if you put four levels of synths you probably won't be able to see anything but the keys below the other synths. This can be fixed somewhat by adjusting height difference and angle though.
