/s_newargs create a new synth

string - synth definition name
int    - synth ID
int    - add action (0,1,2, 3 or 4 see below)
int    - add target ID
[
  int|string - a control index or name
  int        - number of sequential controls to change (M)
  [
    float - a control value
  ] * M
] * N

Note: this command is inherently problematic when used with 
graphs generated by hsc3 since, as a rule, it is not possible
to fix the ordering of control variables.
