render 1/2 length wavs and join them in any audio editor

1/2 length is just that.. half the length of your track. Not half sample rate.

Or why not add a new empty track, set it to resample - or send your mix as a group to it - hit record then come back 3hrz later?

You have to select the time range you want to export in the arrangement window. I always set the loop brace to the area I want to export then click on it. When you go to the export dialogue it will automatically default to export the selected range.

This is not a good ideas as it will limit your High frequency response 10KHz. Like putting everything through a 10KHz low pass filter.

^^^^

The brace is what you need to adjust to get half the length.

Double the tempo or *4 then export.
Open it in a audio editor and process (Timestretch) to get the original tempo.
It's a DIY solution

Joining 2 wavs or handling massive files is not something I've ever tried, so I can't say for sure.

Looking around the web it looks like support for wav files greater than 2GB is patchy at best. Theoretical maximum is 4GB but a lot of programs seem to be restricted to 2GB.

Your best solution might be to convert the files to mp3 first and then use an mp3 file editor to join them together. But I've no experience of handling such large files, so you'll need to google it I'm afraid, unless omeone else here as any ideas.

this seems like an incredibly stupid limitation considering how many dj's are using live and there are many of them doing sets for 4+ hours.

I am sure that the limitation is there just because they feel like being bastards.

more like it's a design flaw that they didn't expect people would like.

They probably didn't really see a 2-4GB file size limitation as a problem back in 1991.

Do people really listen to 4 hour DJ sets all in one sitting? Why not divide it up into much smaller chunks, like 10 minutes each? Chemical Brothers did on Brothers Gonna Work It Out, and it was a great halfway point between "ridiculously long dj set" and "mixtape".

i know people who does that, yes.
i also know people doing musique concréte pieces, and one of them is nearing the 4 hour mark as we speak.
the point is that for a software like this, it's a stupid limitation.

what if you make a generative sound installation and you want to record it to pick out the good parts?

This has got to be the dumbest thing ever. It kind of burns me up considering I always go to bat for Ableton. I do really long mixes 3-4 hours, having to break up the mix just for output is terrible and complete hassle. There should be no limitations other than memory or available storage for outputting a mix!! Get with Ableton, I may have to switch. Such a simple feature to remove. FUUUUCKK!
