I was wondering if it is possible to build a show on a newer ETC board and then import it onto a MicroVision board (the show I'm designer for has only a few hours in the space and has to be run from a MicroVision but I only have access to an Express board).
No is the short answer. Not easily is the longer.
The Microvison is pretty old and in it's prime, could interface with the off-line editing program called ETC Edit. If you had a PC that could run MS DOS, you could install and use ETC Edit to import a .txt show file from another DOS program that I believe was called Trackmaster. Trackmaster in turn could read the USITT ASCII file from Expression Off-Line, which read the disk off the Express, or any ASCII cue file.
It was a complicated process and took some times to get all the steps running correctly. I did the transfers occasionally, but this was 13 years ago and don't now own a PC that runs DOS. Nor can I find my Trackmaster disk.
Hope that helps.
Eric Cornwell at WestSide Systems does this for a fee, maybe if you plead poor he could knock the fee down or run it for free.
Or maybe somebody at ETC still has all these old DOS programs on a machine somewhere.
