Audio MIDI Setup is the Mac OS X utility that allows you to set up audio and MIDI devices. Ad blocker safari. 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. Managing MIDI devices in OS X is pretty simple thanks to the Audio MIDI Setup (AMS) utility that's supplied by Apple. 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. 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.

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.

As discussed in last month's Apple Notes, drivers for Core MIDI tend to live in the Local domain's Library / Audio / MIDI Drivers folder (at the root level of your Mac's boot drive). However, Core MIDI also offers built-in support for USB-based MIDI devices that conform to the USB MIDI-Class specification, so certain USB MIDI devices will actually work without needing any extra drivers. If a MIDI device shows up in AMS, you know that it's been correctly installed. However, there's a slight caveat to this rule because a device can also appear disabled in AMS, which is when it has a fainter appearance than devices that are enabled, and it's important to note that disabled devices will not be accessible to applications using Core MIDI.

There are two common reasons for devices appearing disabled in AMS: firstly, the device might be a USB MIDI device where the driver has been installed, but the device isn't actually connected, or it might be powered down. Secondly, the device might have had its driver software uninstalled from your Mac, but the ghost of the device is still lingering on. You can delete a disabled device from AMS by simply selecting it and pressing backspace — enabled devices cannot be deleted and need to have their driver software uninstalled to become disabled devices first.

If you accidentally delete a disabled device that is temporarily disconnected (but whose driver software is still installed), don't worry: the next time you plug the device into your Mac it will reappear in AMS. Although it's pretty common for MIDI devices to come with installers that automatically install the appropriate drivers on your Mac for you, it's less common for them to come with uninstallers. This isn't a big problem, as MIDI drivers are fairly easy to manage, since, unlike certain types of driver, Core MIDI drivers run in what's known as User Mode, meaning that they run outside of the main core (or kernel) of the operating system, where it's pretty hard for any serious problems to be created that would cause your Mac to crash. In fact, architecturally, MIDI drivers are similar to audio plug-ins, so if you're used to dragging plug-ins in and out of folders, it's pretty much the same idea. Core MIDI applications communicate with your MIDI setup via a background process called MIDIServer. You need to make sure MIDIServer isn't running if you plan to manually move your MIDI Drivers around, and Activity Monitor is the perfect tool for the job.OK, now to look at the way Core MIDI works: when you run the first application on a Mac that uses Core MIDI, a background process called MIDIServer will be started, and one of the things MIDIServer does when it starts is to go through your MIDI Drivers folder and load all of the MIDI drivers it finds. By way of a comparison, this is just like how an application such as Logic will scan through all the available Audio Units on your system each time it's launched.
