Actually, you don't need to do it this way. You just need to change the instrument in Scaler from Flat Piano to OFF.

Thanks for the tip, I think what I wanted was more of what I got at the end, a way to toggle it on/off through something like my foot pedal. I need to play with that settings, was not really aware of it.
