These are great samples. I used them extensively in my music and videos found at www.youtube.com/digitl that have been viewed thousands of times. Have a listen.
These were produced using a variety of techniques: Now the good news- you can download and use for free. Just give me, Erich Izdepski, credit for providing audio samples per this Creative Commons License.

Watch here for more samples, since I am producing new ones regularly. These samples will work in ANY sample/looping software, since they are all 16-bit, 44.1KHz wav files. The samples that begin with "qsr_" are specifically designed for an Alesis QCard. They will properly loop.
