Well, if you couldn't get answers and tried to purchase the product I thought the front of the webpage was pretty explicit. If you sent emails, it may be that they are a tad short staffed and stretched right now, there is a 'conference' in the US called NAMM.

Google NAMM, Pgmusic is a small company and staffing a booth and running demos in another is no small undertaking.

The best thing is to remember what timezone they are in, and use the phone numbers to try and get them in person. So when it's about 5 p.m. your time they are getting out of bed in Victoria. Then they have crumpets and tea. Or scones.
