Great product, very easy to use. Personally, I use it with the Audacity program. With his grip is fast and easy. Hint: Before making your first recording, adjust the level of the input signal using the potentiometer just below the saturation level. (The Audacity of VU meters allow you to view the signal and see the saturation level) Once obtained the right level, locate the position of the index of the potentiometer with a stroke of the pen, this position will remain valid for virtually all subsequent records.
