Build piano UI faster

A piano keyboard needs correct white-key and black-key layout, overlapping key shapes, labels, input events, styling, orientation, flipping, and scrolling and scaling.

UMG Piano Keys handles that foundation for you, so you can focus on the product around it.

Is UMG Piano Keys a full piano roll?

No. It is a piano keys widget. The white and black interactable keys.
It is designed to solve the piano keyboard part cleanly so it can fit into larger music UI systems such as piano rolls, editors, and note tools.
