The "reverse position" function for midi in the transform window does not seem to be working.

Question

So I'm trying to have all of the notes of my midi region play in reverse order. I found out after some research that the way to do this is via the "reverse position" function in the transform window. I opened the parameters for this and it gave me an option to select "inside" a set of measure positions, so I set it to between measure 99 (99 1 1 1) and measure 172 (172 1 1 1) and tried to "select and operate." Nothing. Tried to select manually and then hit "operate." Nothing. I then changed the condition from "inside" to "all" and manually select, then hit "operate," and this time it showed "340 events in one midi region found" at the bottom of the window but still did nothing. I haven't manually counted the notes in the region but that seems like a fair estimate that it's the right number of notes (midi events).
Any idea why this function seems to do absolutely nothing?

Answer 1

((/MAIN/NODE1NODE2 = 'x') EX)
This means that the condition will eval to true or false ONLY if the node exists?
(Note: In the actual scenario, I have an IDOC and I wish to perform a similar check on a tag that may or may not exist depending
upon the situation).
If your requirement is to check if a node exists or not then below is the condition which you should be using:
Left Operand: /MAIN/NODE1/NODE2
Middle Operand: EX
NO right operand in this case
