Hi There is an MTP emulation mode on the Studio 64X which I have used with Logic and SD for many years now - they have the drivers for that built in and the timing is great on Logic. I have only rarely had problems with SD in the past and that has usually been Autolink refusing to play ball. All I have needed to do in either Logic or SD is to nominate the MTP port a device is connected to. Tony > does the Opcode have drivers for that OS?
