## rspline

rspline — Generate random spline curves.

## Description

Generate random spline curves.

## Syntax

    ares rspline xrangeMin, xrangeMax, kcpsMin, kcpsMax

    kres rspline krangeMin, krangeMax, kcpsMin, kcpsMax

## Performance

kres, ares -- Output signal

xrangeMin, xrangeMax -- Range of values of random-generated points

kcpsMin, kcpsMax -- Range of point-generation rate. Min and max limits are expressed in cps.

rspline (random-spline-curve generator) is similar to jspline but output range is defined by means of two limit values. Also in this case, real output range could be a bit greater of range values, because of interpolating curves beetween each pair of random-points.

At present time generated curves are quite smooth when cpsMin is not too different from cpsMax. When cpsMin-cpsMax interval is big, some little discontinuity could occurr, but it should not be a problem, in most cases. Maybe the algorithm will be improved in next versions.

These opcodes are often better than jitter when user wants to “naturalize” or “analogize” digital sounds. They could be used also in algorithmic composition, to generate smooth random melodic lines when used together with samphold opcode.

Note that the result is quite different from the one obtained by filtering white noise, and they allow the user to obtain a much more precise control.
