Guess I should sell my Hog then? No new features in years. Basically the same when it came out around 2004. I feel really bad for those Avo guys though, those consoles have basically been the same since sometime in the 90s. Even worse, ETC Express line anyone? 1992 I believe is when the last revision was done. Those consoles are still in very high demand. Consoles, be it software or hardware, isn't something you just keep adding features to. This school of thought is like saying I shouldn't buy a DMX Operator because no new features have been released for it since it came out.
As for many scenes/cuelists at once, that is something higher end consoles do. The logic in used in programing these types of consoles (the software and show programing) is far more advanced. Adding something like this to MyDMX would turn it into a different product and then raise cost and learning curve substantially. Also, this will add to software complexity and make crashes much more common.
