Why is there only one preset in each SoundFont?
When you load a SoundFont you use your computers resources. The bigger SoundFont, the bigger task for your computer. Our SoundFonts consist of a combination of many sound recordings used in order to obtain a natural, well-sounding product. If we combined several of our sounds in one big SoundFont (this can be done!), it would use more of your computer’s resources than necessary.
