Hello,
I'm looking for a sort of box that look like a calculator. Each button allows to do a different sound.
You can record your melody on it.
And the last thing I know is that it cost approximately 60 or 80 dollars.
Any idea of what it is?

Thank you very much!

Could it be a Stylophone? Below link to picture,
