i dont know much about these programs but is there a computer program that has very good professinal sounds in it that the pros use?and how dose it work?Thanks
I don't know that the "pros" really use computer software at all for handling their sampling chores. Depends what you consider a pro. But I think pros generally tend to use a good hardware sampler like an Akai or E-mu.
The best and most popular software sampler I know of is Nemesys Gigasampler at http://www.nemesysmusic.com/. The quality would depend on whatever sound card you are using (and, of course, the quality of the sample itself). You should be able to find lots of free Gigasampler samples on the net.
