If you're interested in beta testing, just file a support ticket with a request, be sure to include full details of your entire studio setup, your back ground, any previous beta tests from other companies that you've been involved with, what you're currently using the product for and any additional info you'd like to share. More information is better than no information. The support team will pass the beta test request to the QA team who will review your information.
Please note that should we select you for beta testing, you will be required to sign a Non-Disclosure Agreement (more commonly referred to as an NDA). As well as a Test Agreement. We do periodically conduct public betas from time to time which are done through our forum for registered product owners only.
