Finding my .rex files

You can't directly get the *.rx2 files from the "Factory Sound Bank.rfl".

Quadroetc.: You obviously have a lot of experience
with Propellerheads software; is there an indirect
way of calling up the file, perhaps in Reason first,
and then copying/moving it to Logic?

Nope. There's no way to get the samples, or *rx2 files from the factor refill.

If you really want the loop. You would have to use the Dr.Rex player, then export the audio from Reason. Then use Recycle to chop up the audio and create a rx2 file. But this has nothing to do with Logic. It is entirely done in Reason. (It's kinda lame you can't even open up the factor refills with Recycle and manipulate the rx2 files)

If you just want the audio loop, It might be practical to export the audio file from Reason, then open it up in the Apple Loop Utility. Then you would have an apple loop of the rx2 file from the factory Reason refill.

I've actually given up on Reason.

I use Stylus RMX to play and manipulate any of my rx2 files (that I have created). It's a way better rx2 player.
