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.
