thirdspace Posted April 21, 2017 Share Posted April 21, 2017 Hi all I'd like to use my old Emagic MT4 MIDI interface with Sierra and Logic Pro X. Plugging it in via USB I get the red patch light but not the USB light. I see there is a Unitor 2.5 driver but I'm guessing this is now redundant - when I try to install it said: "Your computer does not need this update". Oddly I tried once more and it installed, but still no joy. Any clues?? Quote Link to comment Share on other sites More sharing options...
GCritchley Posted April 26, 2017 Share Posted April 26, 2017 Mine works - Mac Pro (5,1), sierra, Logic latest release. Hit me back with any further troubleshooting ideas, and I'll try to help Quote Link to comment Share on other sites More sharing options...
thirdspace Posted April 26, 2017 Author Share Posted April 26, 2017 Thanks! Did you need to install the driver? Is there a way to check it is installed? Quote Link to comment Share on other sites More sharing options...
GCritchley Posted April 26, 2017 Share Posted April 26, 2017 I think I did install a driver many incarnations ago, but not sure if that's still pertinent. A search for "emagic," or "MT4" shows nothing. here's a screenshot under "Audio Midi setup" - which might be the best place to troubleshoot. Assuming you know what that it and where to find it? I think I ultimately added it from inside that area. It has always simply worked - I've used it since Yosemite and earlier, on this same MacPro Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted April 29, 2017 Share Posted April 29, 2017 This is the driver you need: Unitor Family Driver 2.5 Quote Link to comment Share on other sites More sharing options...
thirdspace Posted April 29, 2017 Author Share Posted April 29, 2017 Thanks David - I have that installer and as mentioned, when I first tried to install it said: "Your computer does not need this update". Oddly I tried once more and it installed, but still no joy. Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted April 30, 2017 Share Posted April 30, 2017 Thanks David - I have that installer and as mentioned, when I first tried to install it said: "Your computer does not need this update". Oddly I tried once more and it installed, but still no joy. What have you tried exactly? Do you have a MIDI keyboard connected to the MT4? Have you tried playing that keyboard and see if it can trigger an instrument in Logic? Since the MT4 appears in Audio MIDI Setup and is not grayed out, that indicates that your Mac recognizes it as connected - so it should work?

thirdspace Posted April 30, 2017 Author Share Posted April 30, 2017 Thanks everyone - put this one down to user impatience!! So I assumed it wasn't working as only the patch light came on when plugged in, but as soon as I open AMS or Logic Pro X the light switches to USB - and works fine for MIDI coming in from my old controller keyboard. I didn't get this far when I posted the question as I gave up when I saw the Patch light - note to self - be more patient! So apologies for the false alarm and thanks for all the ideas and encouragement!! Only unanswered questions I suppose are whether I needed to install the driver at all or whether it would have worked with drivers supplied by MacOS - something for another time I guess! Thanks again Mike Quote Link to comment Share on other sites More sharing options...
