Thanks
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....
Hmmm,
Not so good eh' ?
so the 'record 4 tracks' function will not work without output (hardware
monitoring?) at
the same audio format?
can I just "record" with 4 tracks?
I have used logic in the past but have been followung the development of
jackd and ardour for a LONG time....I am vested in the piece of audio
equipment (maudio quattro)....I guess I couild sell it...I would only
get a nickel though... I really wanted to user ardour to remaster my old
4 tracks...
