This is a PSD file, created with Photoshop CS 5.5. All the elements are made from vector shapes with effects on them. This means you can scale the file to any size you wish. You have to choose the options "Scale Styles" and "Resample Image" when resizing. The piano keys also have an active state, as you can see in the preview. You can simply put copies of the keyboard together to build several octaves.
