Change speed without changing pitch for musician learning (solved)

[gai-luron]

Hello,

For musician, a great idea is the ability to change speed for a song without changing pitch.
In this case musician can play music slower to learning it and play at the same time.
I use frequently this function on my Zoom H4N, but if i can have it in my little sansa clip at any time It would be fantastic.

Thank for this very good firmware.

Regards
