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.

Once the firmware is flashed from a Windows or Mac OS machine, the device is seen as USB class compliant.
This means it doesn't need any drivers to work with Linux and works out of the box with Android and maybe iOS USB recording software.
Didn't try the Firewire part yet but its supposed to not need any driver on Mac OS X, so I suspect it's also a standard implementation.
Will report further experimentations later.

[EDIT] 2016-01-09
Finally took the time to have another look.
Firewire is not currently supported by FFADO.
Will do my best to try and figure it out.
Further informations will likely end up in my GitHub repo.

[EDIT] 2016-01-14
Takashi Sakamoto's doing an awesome job of figuring out the interface.
Follow this thread on the FFADO mailing-list for live progress.
Kudos to Takashi! He really knows his stuff.
