Sooo... it IS in fact now possible to control Syrinscape with API links. I recommend checking out THIS page: <a href="http://www.syrinscape.com/online/" rel="nofollow">www.syrinscape.com/online/</a> This is our thing we (at Syrinscape) built for people using VTTs such as Roll20. I won't go on about it here, since you can find out everything you need to know on the page, BUT the relevant bit for this thread is, we now have API links working on the Online Player, meaning you can control your Syrinscape sounds from within Roll20 using weblinks (these weblinks ping our server, and act as button pushes on Syrinscape = changing the background mood, or starting some music, or triggering a Wilhelm Scream, or a Fireball, or a Wilhelm Scream caused by a Fireball). As Ammo mentioned above, the Syrinscape forums are a great place to find out how all this works etc. Or ask questions here, too. :-)
