So when I bought that drum sample pack from iwantthatsound.com , it came with two files, one full of .wav loops and one full of .rex loops.
I started out using only the wav loops in my logic sessions just for simplicity. I also didn’t want to take the time to learn how to use rex files in Logic.
But then I was working in a song and I needed to slow it way down and Apple’s time stretching algorithm started to deteriorate the sample.
I knew that rex files were made to somehow change timing of the loop but I didn’t know how to use them. I then took to google to learn, and I compiled all my findings below:
Propellerhead is a Swedish company that invented the rex file and makes tons of really cool audio tools like Reason, Figure, and ReCycle.
I found this video on Propellerhead’s site describing exactly what rex files are and how they are made. Watch it below.
After I learned why rex (.rx2) files are so cool, I got really inspired to go change the tempo of my song.
I tried just dragging and dropping the .rx2 file into my Logic session but that didn’t work at first..
You have to download the REX Shared Library from Propellerhead’s website:
After downloading the .pkg from the link above, double click on it.
If it gives you a security error: click settings on your computer -> security and privacy -> allow download
After all that, the REX file still wouldn’t import into Logic.
So then I downloaded the SetRexFolderPermissionsScript.zip at the same link above (even though that page says my current version of logic does not need to).
I ran that script and voila, it worked.
To import your rex file just drag and drop
Click file -> import audio file -> then find your .rx2 file
When I imported my drum loop the tempo changed naturally as I changed my project’s tempo.. pretty magical stuff. Beethoven would greatly appreciate all of our futuristic creative tools. #blessed
