No, that's not what I'm saying. I don't know what Soundblaster cards have soundfont capability, perhaps all of them. I just know the Live! does because I use it. And I meant RAM when I mentioned memory, and that's what the Soundblaster uses.
Up to 50% of your system RAM can be used for soundfonts. So if you have 128mb RAM, you can use soundfont files as large as 64mb. That means you have the potential of using very high quality soundfonts with this card, depending on the amount of RAM you have (and it's very cheap now, BTW). For comparison, the soundfonts that come with the Live! are only 2, 4, and 8mb soundfonts--not very high quality.
You should read the articles I linked for you.
