What is this Brace Symbol attached to the main outs?

Hello! I keep seeing this 'Brace' symbol when watching online tutorials - (it seems to be in older versions of Reaktor?)

I have looked through the math functions and searched here and the manuals- but I can not find it.
Is it some kind of normalising or limiting function?
If so - where is it? (I have Reaktor 6)

Thanks
W.

 

It's a Voice Combiner.

 

It's the 'Audio Voice Combiner' from the 'Auxiliary' catagory and needed at the end of polyphonic structures to output a monophonic mix of all voices.

 

Great. Thanks! I should really go through the documentation - properly. I've had Reaktor a while - but I'm only on my third day. A side question - is it used that much nowadays?

 

Of course, it is absolutely necessary for every polyphonic structure/instrument.

 

Sorry mate - I meant Reaktor itself - is it still popular nowadays?

 

Will, have a look in the NI user library or on the BLOG (above this forum) link and study the articles.

 

Yes - true. I suppose It's the investment of time to learn, but I don't know if the application itself is outdated. I realise it was an open ended and vague question. though.
Thanks for the reply.

 

There are ensembles in the user library over 12 years old: p.e. aero. It's up to date for relaxing. Just create 11 banks of snapshots for this beast building by Roberto Noris in summer 2006.
