Sorry, but what about this?:

"In general, in this day and age, just about any audio software that uses samples and loops grants a "royalty free" license, meaning you are given a license to use the samples and loops in an original composition without having to pay for additional licensing beyond the cost of the software. However, one thing you are usually *not* allowed to do is to use the software to create new loops and samples based on the old ones and resell those. Some will even have a clause that you cannot use the loop or sample in a manner where it is played 'alone' for more than 2-5 seconds without other sounds mixed with it, implying that it could be sampled by someone else and used illegally."
