<a name="alpha"><h3 style="padding-top: 40px; margin-top: 40px;"></h3></a>
_____________________________
**alpha(val)** A value between 0 and 1 will set the alpha blend value for the entire component. Can be useful if you need to fade widgets in and out. 

<!--UPDATE WIDGET_IN_CSOUND
    SIdent sprintf "alpha(%f) ", 50 + rnd(50)/50
    SIdentifier strcat SIdentifier, SIdent
