object IEnvGen extends ProductReader[IEnvGen] with 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 }
