While Grandpa is right that Touch Sensitivity can be used to 'swell" a sound with your right hand, it does nothing to increase the volume of the rhythm with your left hand. Unless one plays like FonzyBear of the Muppets...You know, like a mechanical pounding up and down with the right and lefy hand, kinda like the characters in 'It's a Small World' at Disney .(annoying after a while)

If you notice, when you press the intro and ending button, sound and rhythm swell up and down together, in a flowing, appeasing manor. I don't believe you can achieve this whole effect using only Touch Sensitivity with your right hand, unless I'm missing something. I like to be able to increase the rhythm volume along with the sound volume. I think this is where the expression pedal does it's job.

When you play your sax, you only have to play the sound, and adjusting the volume is controlled by the amount of air you supply. (Ruthie say Doug has a lot of air). There is no rhythm volumn to worry about, thus no expression pedal on a sax.

Therfore, it is my belief that the expression pedal can be used in conjuction with touch sensitivity, and a viable option to have . At the very least, it's there if you want it, even if it's used only as an old security blanket. After so many years with a swell pedal, it's tough to do away with a friend who was always there by your side, lying there, on the floor, waiting to be acknowleged.

Grandpa..what was the contest question again ?
