This is a simple piano that I made. To change the instrument you can click on the buttons at the bottom. To change the volume you can use the arrows to move it up and down. To view keyboard help tick the button by clicking on it. Use the mouse or the keys to play the notes.
The code was written by me. If there are any bugs please point them out in the comments. Feel free to remix Visit my studios; https://scratch.mit.edu/studios/811368/ https://scratch.mit.edu/studios/1384348/ https://scratch.mit.edu/studios/1412230/
