I've been trying to update the OS on my x4 using the instructions on the DSI website, but when I send the update via MIDI OX, the Mopho flashes SYX INVLD. Any suggestions?

What Main and Voice OS versions are you on now? The X4 has been on Main OS 1.1.6 and Voice OS 1.1.2 for at least two years.

It ended up being a problem with the MIDI interface. Thanks for the help, though.
