I wasn't sure if this software had ever been discussed around here, so here are my thoughts on Avatron's Air Display.
It turns out I've been using this app for quite a while but never really gave any thought of what I could do in a laser show context. I'm a drummer/electronic musician, so I had been using this app to move my DAW (digital audio workstation) controls onto my ipad mini which I'd then place next to my drumset. It allowed me to cue up recording without having to get up.
I was toying with my new beyond setup and started investigating OSC control via my ipad when it all clicked. As it turns out, Air Display, made by Avatron (for about $10), allows you to take any Windows or Mac machine and extend the desktop out to any IOS or Android device (or even another computer running Air Display). So I tried it. Installed the software on my pc and ipad, fired up Beyond and dragged the whole window to the 2nd screen and maximized it. I was AMAZED at how well it works. Even with animate all cues turned on it was as if I was viewing it on my main monitor, but now I have TOUCH control and full portability. Now I'm really starting to daydream about what could be accomplished with this and a customized universe.
I recommend this software for everyone with the hardware to take advantage of it. I use it in my every-day business to put my mail reader on my portable device while I do my work on the main screen. It is awesome.
and of course, the disclaimer: I don't work for nor know anyone associated with the development or sale of this product, I just love using it and figured it would be useful to share my experience using it with you all.
Enjoy!
