Roland UA-22 DUO-CAPTURE EX

Category: Audio,GNU/Linux,Hardware,TeardownsRaphaël Doursenaud @ 3 h 49 min

Just got myself this nice little USB audio and MIDI interface.

It works great!

Full support out of the box on Android on all modes using Audio Evolution Mobile and USB Audio Recorder PRO from http://www.extreamsd.com and even native support in Lollipop (5.0) in « TAB » mode.

On the Linux side of things, I was pleased to see full audio support (fairly recent kernel 3.18.6) but MIDI was not working out of the box.
Fortunately, I found that Daniel Mack (@zonque) had already cooked some patches.
Here they are:
0002-UA-22-MIDI-fixup
0001-ALSA-snd-usb-add-quirks-for-Roland-UA-22
Hope these will get pushed upstream soon!

Update: The patch has been merged upstream. Thanks Daniel!

Oh, and if you’re an hardware freak like me, you’ll love seeing what’s in its guts.
Here are the photos of the teardown.
