EDIT Making a dedicated thread for this.
Hi, here’s a function to use if you want to un-alias the first block.

SEE BELOW FOR AN EXAMPLE OF SLOPPY CODING BY KMaki. I can’t believe this thing worked. I actually messed up the for loops with pairs iterating so bad - switched key and value variables with each other. 
So don’t use this.

if was_alias_to_index == 0 then
--It's not aliased

Extra behavior: Check if there are aliases for this pattern track in song
if aliases are found, remap them to the first aliased pattern track in song,
"unhook" this one

Tried this just now with my shortcut wizard tool, but this should work as a generic function too. In short, this is a replacement for the vanilla un-alias shortcut. It just checks also if this patterntrack is a “mother” patterntrack for aliases. If it is, it remaps the first (in sequence) found “child” alias to be the mother for every other “child” alias. (Obviously the numbers change too…)
Oh what the hex. Heres an xrns. This will create a context menu entry for the pattern matrix, and a keyboard shortcut under “Pattern Matrix:Edit”. Hope this solves at least one problem for you, XG2003.

(DISCLAIMER: NOT EXTENSIVELY TESTED. FIXED A PROBLEM JUST NOW, THOUGH.)
Sorry about the mess - made a dedicated thread for the FIXED tool. it was more broken than Hindenburg.
