If your screen size is too small, MakeMusic Cloud can't run properly. Here are a few strategies to make sure your screen is optimized for MakeMusic Cloud:

• When using a Mac, Windows, or Chromebook computer, make your Chrome browser window the size of your entire screen by using the Maximize or the Full Screen function on your device. 
• Check your zoom in Chrome by following these instructions. The recommended zoom setting is 100%.
• When using an iPad, make sure to access MakeMusic Cloud from the Safari browser. If you receive a "Your screen is too small" message in Safari, try rotating the iPad to landscape.
