Parameters: pfield, value

The AddProcessor takes two parameters, one for pfield (positive integer > 0) and one for value (any number). When applied, it will add the user-defined value to the set pfield for all notes.

For example, if you have a SoundObject with notes for an instrument that uses p4 as its amplitude. If you have values for p4 within the range of 78 and 82, such as the following score:

i1 0 2 78
i1 + . 80
i1 + . 81
i1 + . 82
  

If an AddProcessor is used that was set to 4.4 for value 4 for pfield, your notes afterwards would be moved to the range of 82.4 to 86.4:

i1	0.0	0.5	82.4
i1	0.5	0.5	84.4
i1	1.0	0.5	85.4
i1	1.5	0.5	86.4
  

(The p2 and p3 times above are post-processing for a 2 second duration SoundObject with time behavior set to scale.)
