Oops!

The xy calc has stopped working. As a lighting console programmer, this was one of the most useful tools for me. It’s gone now. Opens to a blank screen.
Bummer...
This is a great app but that bug has killed it for me.

Amazing and helpful

This is superb to me as a cinematographer, it just helps me to pickup the light before I even have it in my hands.
I really hope you guys add the new Orbiter fixture so I understand more about this new piece.

Good but..

This is missing a few things. Such as the barn door/speed ring sizes. It is different than the scrim sizes in the M-series. Also it could use the specs on the various ballast dimensions, weight, lamps they support, etc. Otherwise pretty handy app.
