Hi, I suspect I already know the answer, but anyway: I have an (old!) Emagic 'MT4' usb-midi interface, 2-in / 4-out. I want to use it on Windows 7 64-bit.

Ups, yes, the EMI is an audio-interface, the MT4 is a MIDI interface. Completely different hardware but both in the subject line of this thread. MT4, Unitor8 and AMT8 (the MIDI interfaces from Emagic) still work with Yosemite. Ray part 3. The driver is installed automatically.

However Windows doesn't automatically recognise it and the only drivers I can find (third-hand via Google etc) are for Windows 2k and Windows 98 (did I mention that this is an old device!) It seems that after Apple bought Logic and shafted all Logic's PC users, support for all the associated hardware was ceased as well. So my question is, does anyone know how I could persuade my PC to see this MT4 interface? It just seems a bit environmentally unfriendly to go and get another multi-IO interface just because Apple threw their toys out of the pram.

AMT8 RS232 Wiring When bought they discontinued the AMT8 MIDI interface but you can still find them second hand. They can be connected by USB or serial cable (serial cable has the advantage of longer cable runs) but beware, the serial cable required isn't a standard type cable and you wont be able to buy a ready made cable off the shelf. Perhaps the easiest way to make your own is to buy a Null Modem cable, cut one end off and rewire the end you cut off so that it corresponds with this diagram: Pin numbers are normally embossed into the plastic next to the pins; you may need a magnifying glass to see them.
