ODROID-XU4 USER MANUAL

ization became clear, and in 1983 the MIDI specification was developed.

MIDI (Musical Instrument Digital Interface) gained rapid industry ac-

ceptance, and within a few years, a MIDI Interface was found on vir-

tually every sound card and on most PCs with sound chips on the

motherboard. This is no longer the case, but the MIDI interface, MIDI

instruments, and external MIDI synthesizers are still widely used by

musicians and sound engineers. In fact, MIDI is still the de-facto stan-

dard instrument interface, and does not show any signs of falling into

obscurity as have many early computing standards.

What is MIDI?

MIDI encompasses not only the MIDI connector hardware spec-

ification, but also includes the communication protocol used for instru-

ments and synthesizers, and a MIDI file format specification for MIDI

recording and playback. The standard MPU-401 physical MIDI inter-

face is a 5-pin DIN connector. Internal sound cards no longer include

this connector, but it can be found on some high-end external USB

sound modules. However USB-to-MIDI adapters are inexpensive

and widely available. The MIDI Manufacturers Associated website at

http://bit.ly/1Gn2cYw

is a good source for additional information.

Linux Support for Music and MIDI

MIDI adapters, USB Sound Devices, and Music Applications

have wide support on Linux. For example, the Ubuntu Studio project

is an excellent open-source Linux build that has extensive device sup-

port with pre-configured applications. The official Ubuntu Studio site

page has an http://bit.ly/1FFKyvh which will give you an idea of the

range of Music and MIDI applications possible on Linux.

Ubuntu Studio includes some of the most popular audio apps

available - including tools for DAW (Digital Audio Workstations) for

multi-track mixing, sequencers for MIDI music, drum machines, soft-

ware synthesizers, and even music creation via programming. Ubun-

tu Studio is available from the Ubuntu Software Center and Synaptic

Package Manager.

How do I add a MIDI Interface to the XU4 ?

Three basic options for MIDI are available for the XU4:

USB sound module:

If you wish to use a USB sound module, look

for a device that has solid Linux and/or Android device driver support

which includes the MPU-401 interface.

USB-to-MIDI-Adapter:

A number of basic devices are available which

have been proven to work on both Android and Linux. Compatible de-
