Here is a great tip I learned from Mattias.
The problem: when you record a bunch of audio into a Reason (vocals or external synths for example), the file size increases dramatically. Before you know it, you have a file that is hundreds of Megabyes.
If you are collaborating, big files are a pain, they fill up your dropbox or whatever cloud space you are using, and they take ages to transfer.
So you expect to optimse the file size by getting the razor tool and cutting out all the audio segments where there is no sound. Then you choose optimise and save but the file doesnt really reduce?
Here is the solution:
If you trim a clip, you can right-click and select "Bounce Clip to new Recording" which bounces your trimmed section to a new lane in the clip. After that, you can right-click and select "Delete Unused Recordings".
Enjoy
