[PD] How do I get an xeq object (or any friend) to play my sequence reversed?

[Saby Grünwald]

I am working now with the xeq extensions, it's really great, but I don't 
know, how could I reverse a sequence.
I couldn't find much infos on locators, maybe it would help, how to do it. 
Do you have an idea? If it works, I would like to solve the problem with 
xeq, but if you have an other idea to simply manipulate a list, would  be 
also Ok.
Thanx
