I get insufitient memory at 1024

(on a 512MB PC)
I was thinking on making some changes to that macro for that..
There is not much to do about that big erosion device, but there is a branch of 5 devices that could be hidden behind a Multi-Splitter (possibly replacing the swtich with a Multi-Chooser), and one or two devices could be deleted (not being used)
But the macro is still under development, so it will probably suffer some fine tuning later.
I don't know if mem conservation works inside macros. 
It worked for me, I managed to get a result from the macro, though it ran out of memory at 1024
