USB <-> MIDI converter

Hi guys, I need your help.

I have a keyboard with MIDI support (1 MIDI-IN, 1 MIDI-OUT) and some Arduino boards. I need a device that detects by system as MIDI device. The device should send MIDI signal from keyboard to system and from system to keyboard.

I'm so sorry if similar question already asked but I did not find anything good in Internet. My skill in electronics is low and if you could, please provide me with detailed information.

Thank you a lot.

P.S., sorry for my English...

Do you mean devices like these?

I am sure there are similar ones on your country's eBay site as well.

Yes, exactly. I faced with similar devices a few years ago. But I ordered it on Ali Express. Unfortunately these devices does not support Windows Vista or higher and GNU/Linux. One of devices does not work at all...
And Ebay is not good variant for my country. I live in Belarus and a lot of traders does not send goods in my country or makes very expensive shipping (more that 35 USD).

I need device that supports Windows 10, And it would be cool if Ubuntu 14.04 is supported also.

Google "USB to MIDI converter project". A whole bunch of links came up that look useful, like

Looks like this has been done many times before.

Hi BLRplex.

A bit late to reply...but for the community....
Cheap MIDI USB converter mentioned above are pure sh....
They don't support midi exclusive msg, and generate random midi message due to the bad midi parser inside...
Avoid it unless you need midi cable !

My own converter project, Arduino based, to add to the list here :
