Hi NaN

As there has been no response so far, I will take a try.

Firstly, I do not understand your question. Can you provide an example of what your are trying to do, but do it in a regular node canvas, not the Macro canvas?

Secondly, I recollect that Max used the "same" type of node programming for the Macros as is used in the original nodes node canvas.
I think that all of the nodes that can be utilized in a node canvas, can also be utilized in a macro canvas (???)
So are there things that can be done in a node, but not in a macro???
(The macro "input" and "output" tags cannot be used in the regular node canvas.)

A macro canvas CAN contain sub level macro canvas(es).
