This is good...I remember back in the late 80’s - I had a Yamaha RX7 Keyboard - it came with a “breath” input for those that wanted to play wind instruments and record it as if they were playing...breathing out at different intensities would create the sound of an actual wind instrument...
Using Morse code is the same principle. My son has CP and uses the iPad with a talking program called LAMP...there are alot of people that use that as well...
Cool about the Yamaha RX7 Keyboard!
I agree with what you said. This teenager is about to become very wealthy.
