Note that \, since +the frequency (from the "mtof") is a message \, a "*" box suffices +to operate on it \, but the oscillator's output \, being an audio signal +\, needs "*~" instead. The control marked "overtones ON/OFF" is a toggle +switch. Click to turn it on and off. Of the overtones are "off" you +hear only a sinusoid from the forst oscillator.
