int - node ID
[
int or string - a control index or name
int - control bus index
] * N

Takes a list of pairs of control names or indices and bus indices and
causes those controls to be read continuously from a global control
bus instead of responding to n_set, n_setn and n_fill commands. If the
node is a group, then it maps the controls of every node in the
group. If the control bus index is -1 then any current mapping is
undone and control reverts to normal.
