Plays back break point envelope contours (levels, times, shapes) given by demand ugens. The next values are called when the next node is reached.
| level |
A demand UGen or any other UGen returning level values. If this ends, the
| ||||||||||||||
| dur |
A demand UGen or any other UGen returning time values. If this ends, the
| ||||||||||||||
| shape |
A demand UGen or any other UGen: the number given is the shape number according to Env. | ||||||||||||||
| curve |
A demand UGen or any other UGen returning curve values. if shape is 5, this is the curve factor. The possible values are:
| ||||||||||||||
| gate |
If gate is x ≥ 1, the UGen runs. If gate is 0 > x > 1, the UGen is released at the next level (doneAction). If gate is x < 0, the UGen is sampled and held. | ||||||||||||||
| reset |
If reset crosses from non-positive to positive, the UGen is reset at the next level. If it is > 1, it is reset immediately. | ||||||||||||||
| levelScale |
demand ugen returning level scaling values | ||||||||||||||
| levelBias |
demand ugen returning level offset values | ||||||||||||||
| timeScale |
demand ugen returning time scaling values | ||||||||||||||
| doneAction |
A doneAction that is evaluated when level or duration stream ends. See Done for more detail. |
