I am running Ubuntu 14.04 and am fairly new to recording music. I have an Alesis Multimix 8 FX USB2.0 that I am going to use as a mixer. I am curious to know if I can do simultaneous recording on multiple tracks with this settup on ardour. Anyone know if this is possible, and if so, how to do so?
Thanks
as far as i can tell from the alesis description, that mixer only supports stereo output over USB. So you can record only the main outs and not each individual tracks.
As for it working in linux, if its class complient then it should work out of the box. Plug it in, open up qjackctrl and see if its listed and try it see if it works.
A simple google search would have given you this page
http://wiki.linuxaudio.org/wiki/hardware_support#alesis_-_multimix_8_usb_20_fx_usb-2
so far its not supported under linux according to what i have found from google
@seb the user who posted in that thread was a mac user posting in the wrong forum, which leaded to a linux user purhcasing a non supported interface.
people need to use google more often, you can find the answer to just about anything.
people need to be carefull when posting as wrong informatoin can be costly.

its multichannel device!
and small live mixer.
(i know it, ihave it)
Recorded sessions up to 10 tracks, “live”.
On windows and mac os yes it works.
But, it´s not alsa device.
So this usb audio device does not work on/with alsa driver.

no it works not with your ubuntu 
look here

and find one device that works with alsa driver.
thats a much better product description. it has 10 outputs so yes you are right, the description i read might have been for a similar product.
There is always hope though that in the future someone will right a patch to get it working.
