Download Soundfont Enhancer:

Natural Sounding SF2 Player

The free Soundfont Enhancer VST instrument by Gregjazz is a SF2-player perfect for making your instruments sound more realistic by adding randomness to the signal. For a given played note, Soundfont Enhancer works by accessing the other multi-samples in other regions of the keyboard and bringing them into the sound (instead of just playing the single multi-sample associated with the note). The more multi-samples a soundfont consists of, the more realistic the sound will be. The Soundfont Enhancer VST plugin features velocity- and pitch control, amplitude envelope, vibrato, glide and legato. And it comes with several effects: eq, reverb, delay, tremolo, flanger, distortion and wah-wah.
