Envelope Editor
How it works:
An envelope contains an array of {duration,value} pairs called frames. In this example the contour described by these shapes is used to control the amplitude of an oscillator.
- Hit "Queue" to play the envelope once.
- Hit "QueueLoop" to play the envelope repeatedly.
- Hit "Clear" to clear the envelope queue and freeze the envelope player at its current value.
- Drag the points to change the duration and value of frames.
- Click between points to add new frames.
- Hold down the SHIFT key and click on a point to delete it.
