Is there a possibility that you could make the piano have options that are similar to this one? https://recursivearts.com/virtual-piano/
The thing that I like the most on this piano is the "SUSTAIN". I feel like the Tower Unite piano lacks the sustain or just seems as if the notes don't sound long. Idk. Consider it, or don't. It would be pretty cool.
Could also add where you can mute/or change the volume of the piano.
