Frankly, I'm a little disappointed it took this long to create. Graham Parks of Utsire Software created a new app called Touch Bar Piano, and it's exactly what it says on the tin. You can download the app to your 2016 MacBook Pro with Touch Bar, and you have a tiny little piano that you can use to play "Heart and Soul" or "Chopsticks" to your heart's content.
When active, the app shows a tiny keyboard on the Touch Bar's LED screen. You can choose between 128 different instruments — everything from Acoustic Grand Piano to a Gunshot to Applause are options. The piano even supports multi-touch, so you really rock out.
Like a lot of Touch Bar apps, this one is more of a toy than anything useful, but it works and is super fun!
