Image Engineering created a Macintosh based laser show editing software package called Aurora.

Thanks to OSR, one of these systems came to the SELEM event in 2018.

The system uses a DigiDesign Pro Tools Audio Card as the output interface. Instead of connecting to the normal Pro Tools audio interface boxes, Image Engineering had a special output box that contains the electronics for 4 discreet laser projector heads.

This is a picture of the Pro Tools Audio Card. This I believe was the 2nd generation of cards from the Pro Tools System.

This is the IE breakout interface unit. IE used a different type of locking connector for projectors, pre-ILDA DB25 standard:

Here is a picture of the original audio card in the original host:

I will try to get some software screen captures. As I recall it is timeline based in that it uses timecode numbers to fire clips. More info to come.
