Hi, how are you?
I have created a new function for clone a group with only tracks inside (respecting the visual form of each track, except general collapse, and rest, only the visual aspect).
The problem occurs when the group contains more groups. The function return a error.
Is there any way to detect that within a group there is another group?
In this way, if there is one or more groups within the parent group, condition the function to stop it. This would only be valid for a single level group, but at least it would not return the error.
The function “clone a group with only tracks inside”:
function amic_CH04_9M(m, nmg, clg, cbg, nmt, clt, cbt, ncl, vol, pan, dly, sfx, fxt )-- CLONE TRACK OR GROUP WITH A LEVEL

It is possible to add more lines to clone more features (notes, parameters, device chains…).However, cloning (or duplicating) multiple groups and tracks within a parent groupis a challenge for any programmer.In fact, Renoise 3.1 has a bug related to this.
@Danoise, would you dare to write the function to clone up to 5 levels of groups, respecting the visual aspect?
I think this is the most difficult function I have faced so far with LUA code. I invite anyone to try!!! 
Do you dare to write it?You would be a god!
I can not get down from group level 1.From level 2 I crash! – erroooooorrrr!!!
