Well off the top of my head, Reaper, BitWig, Live and Waveform all offer some kind of free demo version that you should be able to use (although some are save disabled which may hamper state testing).
Other than that your best bet is to simply email the company and ask.
One other option, depending on your budget would be to contract a QA company such as this: Development Testing & Customer Support Services Offered
This could be an effective way to check a wide range of compatibility quickly.
