I remember having it on one of my old Roland arrangers, the E-70 I believe it was...I thought it was cool, but I don't remember using it a lot, and I certainly knew what it was designed to do, as it was a feature we specifically demoed during the demonstrations.

I know I can live without it, because I've been doing so ever since the E-70, and actually never even gave it much thought till it was brought up here on SZ.

Since I've become much more familiar with the response characteristics of Yamaha's SA/SA2 sounds, there is less need to free up left hand, but I can see how it can be important to some people, especially if you like to solo a lot over a repeating chord progression and make use the pitch bender.

Let's put it this way...if it was on the Tyros5, I wouldn't trade up my Tyros4 in order to gain that feature.

I felt the same way about the 76 keys...some people are trading up to a Tyros5 just to get 76 keys...I ain't one of them as 61 works just fine for me.
