In release 1.80 added the hi-low sound quiz and the ability to play the midi sound file. In release 1.70 I added the extremely silly and certainly of no practical value - Sound Scribbler feature. The user can specify the sound duration in milliseconds. The Random button will generate 10 random frequency sounds.
Primary application is amusing small children.
The Sound Scribble screen produces tones a longer duration by moving to the right, and of higher frequency by moving downward. The program requires only 8k of memory. The program is freeware. Enjoy, but I make no claims as far as fitness for any purpose.
