Hi
I just got a red guitar strap for my CT-S1 for the purpose of trying out, what it is like to play the instrument in a more freely way.
It takes some practice getting use to play a keyboard in this vertical position, instead for the normal horizontal one.
But, it is quite fun to just play your favorite songs this way.
The video below is just a demontration, and a such, it isn't perfect. - So, please bear with the shortcommings. Thanks.
