In order to create a response transform, launch Tuner. Choose the option to 'Create a new transform'. From there, at the bottom of the page is a check box for Response Transform. Once you check this along with selecting an msi file, hit the 'Create' button. This will launch the setup you specified & begin recording the responses you give it. Once you complete the wizard, the response transform will have been created for you with the responses you just made.
Hope this helps.
