When you've had a little more practice with making music, then you can get a little more involved, by using the PEEK function. PEEK is a function that is equal to the value currently in the indicated memory location.
The value of the variable X is set equal to the current contents of memory location MEM.
Of course, your programs include other BASIC commands, but for a full explanation of them, refer to the BASIC Statements section of this manual.
Let's jump right in and try a simple program using only one of the three voices. Computer ready? Type NEW, then type in this program, and save it on your Commodore DATASSETTETM or disk. Then, RUN it.

Here's a line-by-line description of the program you've just typed in. Refer to it whenever you feel the need to investigate parts of the program that you don't understand completely.
