LagIn

A UGen that reads a signal from a control bus and applies a lag filter to it. This is essentially the same as Lag.kr(In.kr(...), time) .

===Examples===

// portamento
play {
 val c = Bus.control(s)
 c.set(30)   // initial midi-pitch

 play {
   val freq = LagIn.kr(c.index, time = 1).midiCps
   SinOsc.ar(freq) * AmpComp.kr(freq) * 0.1
 }

 c.set(70)
 c.set(100)
}
