Has anyone used the Elektron EGB-1 gig bag with only two Elektron boxes in it? It is made to hold three and has padded dividers. I am wondering if the dividers or the boxes themselves will shift around without a third box in place. I have an Octatrack and a Machinedrum right now. A third box is inevitable in my future but it will be some time before that happens, I need something to carry my gear around in the mean time and would prefer to not have to buy anything new when I do get another Elektron box.
