Is there a way to open two wwise projects at once?

Question

Is there any way to either open two projects simultaneously and span them across screens or open two instances of wwise?
I want to look at an old project I made as reference when building a new one.

Not easy to keep opening and closing each one.
Is this possible?

Answer 1

1. Show system settings
 - Hold the keys [Windows] and [Pause|Break] on keyboard to show the System dialog
 - Click the "Advanced system settings" (on the left)
or
 - type "Advanced system settings" in the start menu
 - select "View Advanced system settings"

2. Go to "Advanced" tab
3. Click "Environment Variables" button
4. in the System Variables, click "New..."
5. Variable name: WWISE_MULTIPLE_INSTANCE
6. Variable value: 1
7. Click OK on 3 dialogs

Now you can restart Wwise twice.  Be aware of not opening the same project twice, you may get into trouble

How can this be done on a mac?

In a Mac, if you select both projects in quick sequence from the Wwise Launcher, both will open as separate Wwise instances. This may be considered a bug, however, and fixed down the line.

On Mac this is already supported by default, the trick is in the file Wwise.app/Contents/SharedSupport/Wwise/support/wwise/cxbottle.conf , where there is a line "WWISE_MULTIPLE_INSTANCE_NO_ASK"="". To disable the multiple-instance behaviour, simply comment this line out by prepending ";;"
