Dear fellow PTB users,  
  
To play a beep, I use the following command:  
  
SND('Play',sin(0:0.3:4000).\*0.75);  
  
and then I can vary loudness, frequency, etc. by altering the values.   
To play a system sound, I do the following:  
  
SND('Play','Wild Eep');  
  
or  
  
SND('Play',Droplet');  
  
My problem here is that I cannot vary the loudness of these system   
sounds. Does anyone know if it possible to vary these sounds?  
  
Thanks,  
Larry James
