Generating tones?

 Generating tones?

I would like to make a couple of simple beep tones in my VB application,
but not the default Beep function.
I would like a higher pitched beep, and a lower pitched beep,
so I can play them one after the other.  I thought that would be a pleasing
sound combination, informing the user of an action completed in the
background.
So, my problem is: how do I make sounds other then Beep?

I appreciate any help on this...

You need to play around with the following API calls located in the
SOUND.DRV file:

Declare Function OpenSound Lib "SOUND.DRV" () As Integer
Declare Sub CloseSound Lib "SOUND.DRV" ()
Declare Sub SetVoiceNote Lib "SOUND.DRV" (ByVal Voice%, ByVal Note%, ...
                                          ... ByVal Length%, ByVal Dots%)

Declare Sub StartSound Lib "SOUND.DRV" ()

... then try some of this code to make a noise:

Sub Annoying_Sounds ()

        CloseSound
        Voices = OpenSound()
        For I = 1 to 10
                SetVoiceNote 1, 40, 16, 0
                SetVoiceNote 1, 91, 16, 0
                SetVoiceNote 1, 140, 16, 0
                SetVoiceNote 1, 237, 16, 0
        Next
        StartSound

End Sub

Play around with the numbers and see what you come up with.

(Hint: if you send a longer series of noisemaking commands, the CloseSound
call shuts your sound driver up)

There are a few more API calls to get the routines which let you pass
octaves, notes, pitches, etc which I can post if you need them.  The demo
code will need to be a bit longer though.
