It's a 24-bit digital-to-analog converter that gives me much better audio than my Mac's built-in audio chip can manage. My MacBook Pro, for example, has the usual built-in speakers for output, but I also have Audioengine's D3 DAC connected to a USB port. Once launched, you can choose any audio input or output available and make adjustments that go beyond the basic features in the Sound Preference Pane. You can find the Audio MIDI Setup app tucked away in Applications > Utilities. Even though Audio MIDI Setup may sound intimidating, it's loaded with controls that go far beyond what its name implies and can help you fine tune the audio quality your Mac pumps out. Please refer to the instruction manual of your interface to set this up.Your Mac's Sound Preference Pane is the go-to place for choosing audio inputs and outputs, but it isn't the only place you can go in OS X to manage your Mac's sounds. The interfaces could be connected via ADAT, S/PDIF, MADI, or other digital connections. If your interface has Multi-device support, which means that they can be combined with other interfaces, then the devices will appear to Live as a single entity and the communication between the units will be handled by the main interface and its driver. Otherwise, if your interface has Multi-device support, check the section below.

Check this third party video tutorial for instructions. It is possible however to combine interfaces using ASIO4ALL. However if using the ASIO driver, it's only possible to select one device as both input and output in Live's preferences. If using the MME/DirectX driver, you can select two different devices for input and output. On Windows, it's not possible to create aggregate devices at a system level. If your interface has Multi-device support then we recommend connecting it with another suitable hardware device instead. Latency might be misreported and connectivity issues are more likely to occur. This article on the Apple knowledge base describes the process of creating an aggregate device with the Audio MIDI Setup utility.ĭisclaimer: However useful, aggregate devices cannot be expected to perform as well as a configuration based on a single hardware audio device: under certain circumstances, clocking errors can take place, resulting in audio drop outs and generic performance issues. This new group of devices appears as a single Aggregate Device in Live's preferences. It's also possible to combine multiple audio interfaces into an aggregate device at a system level.Ĭreating an aggregate device is a way to group multiple audio interfaces into one virtual device so that Live can communicate with a single, solitary virtual audio interface. On Mac, it is possible to choose different interfaces as Input and Output device in Live.
