Dgeom

A demand-rate UGen that produces a geometric series. Each value is calculated as

x[t] = x[t-1] * grow

With x[0] given as argument start.

===Examples===

// increasing frequency
play {
 val in = Dgeom(1, 1.2, 15)
 val tr = Impulse.kr(5)
 val v  = Demand.kr(tr, in)
 v.poll(tr)
 val f  = v * 30 + 300
 SinOsc.ar(f) * 0.1
}
