Turning off the swing!

[legitum]

I have added a swing symbol using the expression tool, which appears to have turned all my straight quavers into a triplet feel, i.e. swinging. How do I turn this off though when I reach a section of the piece where I no longer want it to apply? There may be a musical symbol that does this, but if so, I don't know it. I was tolerating it for a while, but am working on a piece at the moment where its driving me potty. Thanks!

One way would be to create an expression as "no swing" and set the swing in the playback tab to None.
