Hi Yaron,
Thanks, but I'm looking for a kind of search and replace method.
I'm new to Lua and finding it a bit confusing.
Something like this: search all group names, IF any contain the string "Red 5", replace that part of the name with "Blue 8". So a group named "Piano C3 Red 5 Release" will be renamed "Piano C3 Blue 8 Release".
cheers
Dan
