This is a fun little program I wrote when i started using the sound command. All the keys on the computer make a different sound, Plus it looks cool (i put in some screen effects. You can change how long the notes can go by using the arrow keys.

code:


var Key : array char of boolean
var Ch : char
var Font1 : int := Font.New ("Arial:50")
var Font2 : int := Font.New ("Arial:30")
var Font3 : int := Font.New ("Arial:20")
var X1, Y1, Size, C : int
var X2, Y2 : int
var L : nat2 := 100


procedure DrawStuff
    randint (X1, 1, maxx)
    randint (Y1, 1, maxy)
    randint (C, 1, 15)
    randint (Size, 1, 200)
    drawfilloval (X1, Y1, Size, Size, C)
    drawoval (X1, Y1, Size, Size, 7)
end DrawStuff
procedure DrawLines
    randint (X1, 1, maxx)
    randint (X2, 1, maxx)
    randint (Y1, 1, maxy)
    randint (Y2, 1, maxy)
    randint (C, 1, 15)
    drawline (X1, Y1, X2, Y2, C)
end DrawLines
procedure Pause
    Ch := getchar
end Pause



setscreen ("graphics:max,max,nobuttonbar")

colorback (7)
cls
Font.Draw ("Silly Keybord", maxx div 2 - 200, maxy - 200, Font1, 12)
Font.Draw ("(press any key to continue)", maxx div 2 - 200, maxy - 300, Font2, 12)
Font.Draw ("Made by: Peter Watt", maxx div 2 - 200, maxy - 400, Font3, 12)
Pause
loop
    cls
    Input.KeyDown (Key)

    if Key ('1') then
        DrawStuff
        sound (25, L)

I was really bored so i took your idea and created an onscreen keyboard that does pretty much the same thing, so here's the code:

import GUI

setscreen ("graphics:400;300")

procedure sound1
sound (25,50)
end sound1
procedure sound2
sound (125,50)
end sound2
procedure sound3
sound (225,50)
end sound3
procedure sound4
sound (253,50)
end sound4
procedure sound5
sound (425,50)
end sound5
procedure sound6
sound (525,50)
end sound6
procedure sound7
sound (625,50)
end sound7
procedure sound8
sound (725,50)
end sound8
procedure sound9
sound (825,50)
end sound9
procedure sound10
sound (925,50)
end sound10
procedure sound11
sound (50,50)
end sound11
procedure sound12
sound (150,50)
end sound12
procedure sound13
sound (250,50)
end sound13
procedure sound14
sound (350,50)
end sound14
procedure sound15
sound (450,50)
