You can reliably use it for playback but only with two channels. It
works with 4 channels and alsa native programs like ecasound or arecord.
The main problem turns out that it can only record in big endian format
but plays back in little endian format. This means someone has to write
a layer for alsa which automatically converts big endian to little
endian when the quattro is in use. Pretty annoying and lame. Until this
is done all recordings will sound noisy due to rounding errors or some
other bs.
If I count the design "errors" that maudio made with this device I think
there are 5.
1: Two clock synced stereo channel boards instead of one 4 channel board.
2: Only able to run reliably with lowish latency (480 bits) at 48000hz
(applicable to all usb devices though).
3: Input only reads big endian format.
4: Output only accepts little endian format.
5: Cannot recieve power from the usb port. Requires external adapter.
If you want to buy a good multichannel device for portable recording you
can find better and more user friendly designs in the firewire range
these days.
If you can wait for a few months RME will release their next gen which
should be completely firewire compatible....
