Notice how the MT4 device appears fainter than the other devices, which indicates that it's currently disabled.When you attach a MIDI device to your Mac, it should show up in Core MIDI, assuming you've installed the appropriate driver software for the MIDI device in question. The MIDI Devices tab of Audio MIDI Setup shows MIDI devices available to Core MIDI applications. The built-in devices are a subject for another day, but simply put, the IAC Driver manages MIDI ports that enable MIDI messages to be sent between applications running on your Mac, while the Network device sets up MIDI ports enabling messages to be sent between applications running on different Macs. In the application's MIDI Device tab you'll see visual representations of the MIDI devices available on your Mac, which include those that are built into Core MIDI (OS X's MIDI framework that arbitrates communication between applications and MIDI hardware), such as IAC Driver and Network, and any additional hardware MIDI devices you've attached to your Mac. Managing MIDI devices in OS X is pretty simple thanks to the Audio MIDI Setup (AMS) utility that's supplied by Apple. This month we're going to delve into the MIDI Devices tab, in order to explain how applications work with the MIDI hardware you've connected to your Mac. Set the MIDI Output of the feelyoursound.Audio MIDI Setup is the Mac OS X utility that allows you to set up audio and MIDI devices.Set the MIDI Input of the DAW to the newly created MIDI port.Again: Name the port as you like, but only use English characters (the second port name in the screenshot wouldn't show up in the software, for example). Create a new port by clicking on the "+" button below "Ports" (see the screenshot below).You can rename the Device Name if you like, but please only use characters that are available on an English keyboard! "IAC Driver" is fine, "哈佬" not so much.Activate the "Device is online" checkbox.Open the "Window" menu and click on "Show MIDI Studio".

macOS / OS X doesn't come preconfigured with such a connection, but it is pretty easy to set one up. You need some kind of "Virtual MIDI cable" to connect two MIDI apps with each other.
