Casio SA 47 Tone upgrade

[Desonkeii]

Hi everyone!
I recently purchased SA 47 model and noticed the harmonium tone is only "one reed tone". Where as when I download a free harmonium app from Google play store, the tone is a wonderful "two reed tone".

I was wondering if it's possible to upgrade harmonium tone on a SA 47 model?

Hope someone can help me on this matter.

Thanks guys

Casio does not offer a sound update for that keyboard. Don aka B3maniac
