Lag in the Time of Cholera.

I updated my Moog synth to use low frequency oscillators to modulate the amplitude a while ago , finding a new use for the Lag Ugen in the process. 

Here's the relevant bit, 

var lfo1 =, 0.1);
var lfo2 =, 0.1);
var lfo3 =, 0.1);

When I put it onto my oscillator array the lfo modulates the multipler of the Ugens. 

Why the Lag?

Without it it sounds pretty bad, the sudden changes in amplitude cause a nasty clicking sound. Lag smoothes out the waveform so that the change is more gradual and sounds much better.
