No it does not I think, at least not on the version I have installed currently. RIYA dacs only works on Windows so I believe the author has chosen not to support it since Maxwell is a multi-platform program.
That's my project too so I sell it as an option together with the helios on ebay. It has a completely free version so you can try that before deciding if you want to buy: http://pages.bitlasers.com/lasershowgen/
The full version will let you make proper shows in a timeline with layers. But it's not quite as powerful as other more expensive laser show suites obviously. LSX has a great reputation if you want something advanced.
