IEnvGen

object IEnvGen extends Serializable

Envelope generator UGen with random access index pointer into the break-point function.

Warning: The envelope must be generated using IEnv not Env . IEnv has a completely different format. Using the wrong format ( Env ) may crash the server.

To construct a manual envelope without the use of the IEnv class, the format should be as follows:

val env = Seq[GE](offset, startLevel, numSegments, totalDuration,
duration1, curveType1, curvature1, targetLevel1,
duration2, curveType2, curvature2, targetLevel2
...)
Examples
// mouse controls index
play {
  import Curve._
  val env = IEnv(0, Seq(
    (0.10, 0.6, lin),
    (0.02, 0.3, exp),
    (0.40, 1.0, parametric(-6)),
    (1.10, 0.0, sine)))
  val dur = Mix(env.segments.map(_.dur))
  val gen = IEnvGen.kr(env, MouseX.kr(0, dur))
  SinOsc.ar(gen * 500 + 440) * 0.2
}
