Creative soundcards are not pro cards, but designed for the consumer market and for this they are excellent value for money, offering everything the consumer needs, however if you are a pro (Or you require a card for pro use) you will require a soundcard dedicated to just music, (Creative is Jack of all trades, but a master of none) which means getting your wallet out Im afraid.
Hope this helps
