I use that one. It is USB Audio Class compliant, except for the mixer
part.
Thank you,
IIUC it has got a build in mixer, but even if it shouldn't work with
the patch, it could be used with ALSA mixer, without build in special
mixer features, right?
The patch exposed the internal mixer matrix as normal ALSA mixer
controls. It is in mainline kernel since some 3.x version, I don't
remember exactly which. So you can use the mixer matrix with any
alsamixer app. I use qasmixer, which handles the high number of
controls better than other UIs. Next time I am in the audio room, I
want to try AlsaJsonMixer, which has a specific UI for the Scarlett:

One thing that isn't exposed in the mainline kernel anymore is the
"save state to hardware" feature, which allows the device to be used
stand-alone, without a computer. But it seems to store the last values
anyway - maybe the values are saved by default by the driver at some
point, I'm not sure.
I have managed
to run it with JACK at 64 samples, 2 buffers @ 44100 Hz,
with an RT patched 4.x kernel. That's a bit flaky though, 128 samples
is more reliable.
128, 2, 44100 = 5.8 ms would be perfect.
Excepted of the missing ADAT outputs, it seems to be perfect for me.
Anyway, it still is interesting for me. Did you experience any
durability issues, IOW how long and how much did you use it?
I have it since January 2014. I used it almost daily for half a year or
so. I lugged it around to a rehearsal room and to a few performances.
It has a solid thick aluminium case which is very rugged - I could
probably stand on it without problems. :) The plastic knobs are OK.
I've recently noticed some scratching noises on one of the pots. I hope
it can be replaced.
I ogled with the soundcraft signature series (no ADAT
and no MIDI, but
a mixing console), but fear durability issues.
FWIW in parallel I ask for iPad 2 compatibility at

I don't have an iPad so I don't know.
