ALEA::BROWNIAN2
Arguments: nc binf bsup long sigma [generic-function]
Random walk, simulation of the brownian motion with pitch parameters.
<sigma> is associated with the <bandwidth> of the gaussian distribution,
<nc> the initial value in midi-cents,<long> the length of the sequence
and <binf> and <bsup> the inferior boundary and the superior boundary in midi-cents.
Warning: boudaries are considered as elastic.
