Part 7: Sound

I have mostly typed out the listings from the book as they were printed

The exceptions are that I have added REMs at the top stating the page in the book where the listings began, and adding book title and author lines.

In a few cases, where it was very clean and easy to do os, I have added lines to dump the execution and exit directly to the computer's main MENU.

All of these additions are obvious in that I have inserted my line numbers between the original 10,20,30,... line numbers. This way, if you want the exact original code, you just have to remove the single or XX5 lines.

Note: These additions have altered the original file byte sizes, but I have kept the values which the authors always put on line 10. 

The Files:

MUSKEY: Make sounds by pressing keys.  Simple to playwith and has a fun feature "as an interesting sidelight, you can play messages.  With the program runnning and waiting for your keyboard input, press any of the function buttons at the top of the keyboard.  You'll hear each letter of the message assigned to the label "played" by the program.  You can even use the PASTE button, from the MENU, go to text mode and type in a message,  Use the Select and Arrow Key buttons to select a portion of the message or all of it for copying into the PASTE buffer.  Now go back to the MENU and place the cursor over the MUSKEY program and press ENTER.  BASIC will automatically load the program and start executing it.  WHen the display indicates that the program is waiting for you to start typing keys, press the PASTE button and your message will be played for you."

MORSE:  Learn Morse Code.  Either type a letter and hear it or hear it and try to type it.  You can control the speed and tone.  "Using the same technique described for MUSKEY you can enter entire messages for play back."  

MUSIC8: Create your own tunes.  Program shows staff lines. Use the up/down arrows to select a note, press Q for quarternote, H for halfnote, W for whole note or E for eight note. THE 3 or # is used for sharps, the B or b is used for flats.  As you make selections the note name is printed below the notation.  Press Enter to play.  Program does not include save or loading... the authors tell you do do it yourself ;)
