I GOT A GREAT IDEA!!
Make the paino play with numbers insted of clicks then we can actually like be playing one!!
This is pritty cool!
An alright gadget, pretety bland. Another suggestion for the next one is to add more instruments, maybe a guitar or a drum kit, a metronome, some options to toggle things like the volume, the look of the piano, the note names to show up on the keys and a way to customize what the keyboard looks like. Everything else i would have suggested has been included in you description. Good luck for the next one.
OMFG I LUVS IT I LUVS IT I LUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUVS IT!
It was a good idea, but you should make it so that you can use the keyboard to control the piano keys.
