The Spline node provides an arbitrary piecewise-linear envelope. That is, it connects some points with lines to make a function. The node's input takes the x-coordinate and output provides the y-coordinate.
Among the Spline node's uses are pitch envelopes, amplitude envelopes, oscillator waveforms, velocity curves, and automation control.
- To create a control point, double tap on the function area.
- To move a control point, drag it.
- To delete a control point, double tap on it
The value boxes on the left control the min and max value of the function. Control for the scale of the x-axis will be added in a future version.
The red dot shows the current input and output values.
