12.25 Working with Multiple Instances of REAPER
If you wish, you can have more than one instance of REAPER open at the same time.
Kind: concept (user-guide-section) Chapter: 12 Managing The Overall Project Source: REAPER User Guide v7.70
If you wish, you can have more than one instance of REAPER open at the same time. This can be useful, for example, if you have multiple monitors and need to work on two or more projects at the same time, with each project kept always in view. With project tabs this is not possible, but there are two other ways of doing this:
Spawn new instance of REAPER.
Open the Action List and run the action File: Spawn new instance of REAPER. This is the simpler option and will open a separate instance of REAPER in a new window and with its own preference options, but sharing the same configuration file. You can, for example, copy and/or move media items between the two (or, indeed more) instances. Each instance of REAPER is independent of the other. However, this method might not be preferred if your monitors are running at different resolutions.
Make a separate portable install of REAPER.
A portable installation of REAPER (in a different directory from your main REAPER installation) will have its own configuration file and settings. It can be run independently of, and alongside, your main REAPER version and allow you to do everything that you can do with a spawned new instance.
