Pseg defines a function of time as a breakpoint envelope using the same parameters as Env. These patterns can be used to describe tempo or dynamic variations independent of the rhythmic patterns that express them.
Pseg.new(levels, durs: 1, curves: 'lin', repeats: 1)
Arguments:
| levels |
A Pattern that returns the levels. The first level is the initial value of the envelope, all subsequent values are interpolated. |
| durs |
A Pattern that returns segments durations in beats. |
| curves |
a Symbol, Float, or an Array of those. Determines the shape of the segments. |
| repeats |
a number.
The possible values are:
\step | | flat segments. | \linear | \lin | linear segments, the default. | \exponential | \exp | natural exponential growth and decay. In this case, the levels must all be nonzero and the have the same sign. | \sine | \sin | sinusoidal S shaped segments. | \welch | \wel | sinusoidal segments shaped like the sides of a Welch window. | \squared | \sqr | squared segment. | \cubed | \cub | cubed segment. | | a Float | | a curvature value for all segments. 0 means linear, positive and negative numbers curve the segment up and down. | | an Array of symbols or floats | | curvature values for each segment. |
