Here's a side by side comparison of the soprano sax I tweeked. Folks I started with the most dull and lifeless soprano sax you could use "The GM soprano sax".

The first half is the sound I started with (boy is it awful and dull). I just selected the sound and played. The second half plays the same melody but with my edited version of it. Keep in mind this is an edited version of the GM soprano sax--not the preset soprano sax. I think the difference is "night and day". I'll be getting a new volume pedal (very soon) so I'll have better control of the sound.

IT'S IN MP3 FORMAT I forgot to convert the last demo "sorry".
