Coding Music with Sonic Pi - Adventures in Raspberry Pi - page 145

• The error panel —The lower panel on the right side. This is where errors will be
displayed if there is a problem with your program, or a bug—for example, if you
have made a syntax error or perhaps mistyped a word.
• Workspaces —You can use different workspaces to create and save your code.
In this adventure, you will use a different workspace for each exercise. You can
move between workspaces using the tabs along the top of the programming
panel.
• Play and Stop buttons —Click these buttons to start and stop your music
scripts.
• Save button —Sonic Pi will automatically save what you write in the program-
ming panel. However, if you want to save your code into a text file to store it
elsewhere, you can use the Save button at the top of the application to do so.
