WHERE DO I FIND THESE ANGLED MIDI CABLES?
The Modor NF-1 can be built into a standard 19" rack using the (always included) rack ears. This means the connectors for power, audio and MIDI are at the top side. The lower part of the backside of the Modor NF-1 is recessed such that you don't lose precious rackspace above the NF-1 in this case.
But that space is not big enough to fit any cable. Angled audio cables are rather easy to find, but you also need MIDI cables with a 90° angle at one end. These cables are manufactured for example by Manikin Electronics: http://www.manikin-electronic.com/Products/Accessories/.
One place to buy them is here: http://www.schneidersladen.de/en/manikin-midi-kabel-2m-gewinkelt.html
There are other brands too that make angled midi cables, but we can't garantuee they fit. So far,we only tested the Manikins. Feel free to report us your succes/failure with other brands' cables! firstname.lastname@example.org
