additional parameters: if1, irise, idec, if2, iatss, iatdec


In this variation of 01_01_2B all input arguments of ENVLPX are
directed from within the score file. This allows an exploration
of the functioning of this somewhat more complex unit generator
of the Csound language. 

In particular, the variables iatss and iatdec are new. Both
specify normalized target values: final amplitude values are
obtained by multiplication with the iamp variable.


Here are some results:

iatss:   = 1      steady state period remains steady
         > 1      growth during steady state
         < 1      small decrease (.9) works well

iatdec:  = .01    ideal
         = .1/.2  compared for two durations:
                  idur=2 sec better than idur=4 sec.
         > 1      amplitude grows louder during decay


Examples: 

   iatdec = .01   ends at 1/100th of the max amplitude
   iatss = 2      exponentially strives to a point iamp*2
