USB AUDIO CLASS-COMPLIANT OPERATION
The UltraLite-mk5 is a USB audio class-compliant
device. This means that you can connect it to your
Mac (running Mac OS 10.11 or higher) with a
USB cable and use it without installing any
software drivers. The computer recognizes the
UltraLite-mk5 as a USB audio device and makes
its inputs and outputs available to your host audio
software. Basic settings, such as the hardware’s
sample rate, are made in either your host software
or the front-panel menu.
☛ In this scenario, the UltraLite-mk5 provides
basic audio input and output, and no software
driver installation is necessary. Use the Mac’s
Audio MIDI Setup utility to manage the
UltraLite-mk5 audio inputs and outputs for your
Mac.
Connection to iOS devices (iPad and iPhone)
Audio-class compliant operation allows you to
connect the UltraLite-mk5 to any iOS device with
a standard camera connection kit adapter. The
UltraLite-mk5 then provides multi-channel audio
I/O to your audio apps. Use your audio app to
configure the number of available audio channels.
SOFTWARE INSTALLATION
If you don’t want to operate the UltraLite-mk5 as a
USB audio class compliant device, or if you are
using Windows on a PC, install the software as
follows.
1 Visit www.motu.com/ultralite-mk5-start to
download the latest Mac or Windows Gen 5
installer.
2 Run the installer and follow the directions it
gives you.
☛ We recommend that you run the software
installer before you connect the UltraLite-mk5 to
your computer and power it on. This ensures that
all driver components are properly installed in
your system.
☛ To allow support for a wide variety of
platforms, the Ultralite-mk5 appears as a USB
Class Compliant Ethernet device (USB-CDC-
ECM) in the Network settings for macOS and
Windows. This network port is currently used by
CueMix 5 to communicate with the UltraLite-mk5
on Windows and iOS, and may support other
platforms in the future.
AUDIO DRIVERS
The installer provides a USB audio driver for Mac
(CoreAudio) and Windows (ASIO and Wave).
Industry-leading I/O latency performance
On macOS and Windows, the UltraLite-mk5
driver provides exceptionally low I/O latency
performance. For example, with a 32-sample
buffer size, an UltraLite-mk5 interface operating
at 96 kHz produces round trip latency (RTL)
performance of 2.4 milliseconds (ms) on macOS.
RTL is the measurement of the time it takes audio
