GEN16

  f  #    time    size    16    beg    dur    type    end

Description

Creates a table from beg value to end value of dur steps.

Initialization

size – number of points in the table. Must be a power of 2 or a power-of-2 plus 1 (see f statement). The normal value is power-of-2 plus 1.

beg – starting value

dur – number of segments

type – if 0, a straight line is produced. If non-zero, then GEN16 creates the following curve, for dur steps:

   beg + (end - beg) * (1 - exp( i*type/(dur-1) )) / (1 - exp(type))

end – value after dur segments

Note

If type > 0, there is a slowly rising, fast decaying (convex) curve, while if type < 0, the curve is fast rising, slowly decaying (concave). See also transeg.
