Can you use ethernet cable to run midi signals?
« on: June 05, 2017, 01:06:57 AM »
My midi controller has both usbMidi and Din Midi - so three cables.
I find that a bit of a PITA so I want to run those signals through an 8 core ethernet cable/RJ45 so I only have one lead to connect.
As far as I can see, there are enough conductors available but I don't know anywhere near enough about electronics to predict whether there will be cross talk issues.
Question is, can I get away with that or not, it would be so much neater to have just one cable instead of the three that are bundled together at present?
I am playing all the right notes. But not necessarily in the right order.

Yes you can. The VG99 uses an ethernet cable to connect two midi signals and power to the FC-300 (RRC2) . So if Roland can do it, you can as well.

Cheers sixeight! Don't forget to have a look at that midi queue code I wrote for you!  :)

Just ensure you use 'twisted pairs' for each circuit, which will help both with cable capacitance, cross talk, and emitted noise.

pair 1 = pins 5+4
pair 2 = pins 1+2
pair 3 = pins 3+6
pair 4 = pins 7+8

shielded UTP cable is best for this application

maximum distance for a USB cable is 5 metres (16 feet)
a midi cable can exceed the recommended 50 feet recommended limit, and has been known to work up to 400 feet.

The VG99 also uses these pairs:

And there is an off the shelf solution for MIDI over Cat-5
