Oh boy....
I will save you a lot of hassle and frustration.
Don't buy that Alesis card. It is one of the worst working soundcards on the planet, and chances are , you will be yet another person who bought, tried like hell to get it to work the way the advertise it will, couldn't get it to, took it back then asking on here what card WILL work.
I have not heard anything bad about the MOTU 2408. Yes, a lot more money, but at least it works.
Good luck.
