When I used to teach students with electronic keyboards not one of them continued beyond a few years. They were technically proficient, however, the one thing lacking in their playing was sensitivity.
If you have no sensitivity it sounds like banging on the piano. Contrast that with the most beautiful music you’ve ever heard come out of the piano. That is sensitivity.
As a student you will only become as sensitive as the instrument you practice on. Students on keyboards tend to become frustrated when they can’t do on their keyboard what they can do on the piano at their lesson. The students who began on a keyboard, but actively sought a piano and found one, they found piano much more rewarding and stuck with it.
If you really want to learn to play the piano, find a piano. You will be so glad you did.
