// You'll notice that these 'if' statements don't require curly braces "{}".
// This is because there is only one outcome if the statement is true.
if (CurrentCount==1){

}

}

myOscOutput=mySwitchableOsc.sinewave(CurrentCount*50);//one osc object can produce whichever waveform you want.
}
this.output=myOscOutput*myCurrentVolume;//left speaker
