ODROID C2 USER MANUAL
Sound Cards and Devices for MIDI File Playback on the C2
Not all sound cards and modules provide native MIDI file play-
back capability, including the ODROID USB sound card, but many oth-
er USB sound cards do, so make sure to consult the device’s specifi-
cations. Professional-level USB MIDI synthesizers are also available,
including samplers by Roland, Ensoniq, Kurzweil, Roland, and Korg.
Experimental Music with the C2
Using an ODROID-C2 for computer music opens up possibilities
beyond those of traditional computer music performance, productions,
and engineering. A MIDI Interface and any number of sensors could be
used to create unique musical instruments. For example, a pressure
transducer could be used as a MIDI breath controller, ultrasonic trans-
ducers could be used to make a Vulcan Lute, a string-less harp, or a
super-theremin, or a capacitive touch controller such as the Freescale
MPR121. Using conductive paint for the capacitive inputs could inspire
even more interesting inventions.
Android
Android is easy-to-use, yet powerful operating system, intend-
ed for smartphones, tablets and other portable devices, but also runs
very well on the ODROID-C2, not only as an inexpensive testing plat-
form for building Android applications, but also as a set-top box for vid-
eo and music streaming and playback, a general-purpose operating
system capable of web browsing, social networking, remote control of
other computers, and much more.
Desktop Environment
The Hardkernel Android image offers several Android Tablet fea-
tures, including two pulldown menus at the top of the screen. The top
left menu shows notifications and application information. The top
right menu offers direct access to the operating system settings. To
