Elektron synths use sysex for OS updates and data saves. I was poking around on their web site and found they had a handy utility for sending and receiving Sysex. they have windows and mac versions.
You can download the app here http://www.elektron.se/support-and-downloads.
I used it to upgrade my Analog Four to the current OS 1.06 and it worked great.
