Has anybody had any success with advanced macros?

Advanced macro programming has not been implemented.   There is a certain amount you can do by using other targets as variables but it is still very limited.  Depending on what you want to do it may be possible to use OSC to interface an external program to do some of the macro behavior you are looking form.

I've been requesting this for quite some while. What EOS has just barely qualifies for the term macro in my oppinion, even our old KELLER CNC-milling machine could do more complex things :D

In eos, i cant even call a macro and give it or return parameters

I'd just implement LUA, my 2 cent.
