This is a reply recently posted to a question on Quora: it assumes Soundloom, like all apps, is installed (as we suggest) in /Applications. Otherwise, just locate it wherever it is.
"If you notice that an app looks different than you expect on your Retina display,
try opening the app using Low Resolution mode:
Quit the app if it's open.
In the Finder, choose Applications from the Go menu.
In the Applications folder that opens, click the app's icon so it's highlighted.
Choose Get Info from the File menu.
Place a checkmark next to "Open in Low Resolution"
Close the window and open the app again.
