Program Printout: Beethoven

Beethoven is a remarkable program which allows you to produce music from your T/S1000/ZX81. Stephane Crainic of Paris has linked hex values to the tones available from the speaker of your television set and has produced a table allowing you to convert the notes of the musical scale into those values.

When you have typed in the program, enter GOTO 110 so that you can read the instructions and the table of scales and hex codes. Then transpose your tune into hex. After reading the instructions and pressing keys to continue, the screen will show 0/9998.

Enter LIST 10, EDIT, and alter the A$ to the list of the hex values into which you have converted your tune. Increase the volume of your TV, enter GOTO 1 and your tune will be produced. The notes produced are all off-key but the quality is certainly acceptable when you consider how they are made. Lower-case letters in our listing signify inverse video.
