Hi!
Anyone here who have any recomendations?
The best thing would be a case that I can be fold out and used on a keyboardstand.
Now I use a wooden plank that they are placed on. Would like to skip that… 
Lots of people here use Pelican 1510
there is another elektron box underneath OT, and some room for cables, PSUs, laptop
I’m looking for a trolley hard case for my Octa & A4, anyone use one of those?
