Scheduler Question

You can, but not in the way Spectrum's scheduler did it.  With Borealis (Aurora's scheduler), you'll need to change the way you view "show" and "non show" sequences.  You'll want to ignore the start of show sequence, and simply use the loop.  Just select the sequences you'd like to play, and during "non show times", create a blank audio file for whatever time you need to keep the show times on track (which you can create in Audacity) and program any lights to be on or off as you see fit.  In Aurora, there is no difference between a blank sequence (equivalent to Spectrum's "animation" sequence) and a normal show sequence (Spectrum's "music" sequence), except the fact you are using a .wav that has no audio. 

So at 5pm, play sequence 1,2,3, blank 19 minutes.  This puts you at 5:30.  Then play sequence 4, blank 27 minutes, which gets you to 6:00.  Play 5,6,7, blank 18 minutes to get you to 6:30.  Then play 8, blank 26 minutes to get to 7:00. 

So if we were to name your blank audio sequences B19, B27, B18, and B26 (the numbers indicating the time in minutes, your loop would look like this:

1,2,3,B19,4,B27,5,6,7,B18,8,B26.  This will get you from 5pm to 7pm, at which point the loop would start over.  Schedule that show to end at 9pm.  From 9pm to 10pm, create another show that is only an hour long, and your show will end at 10pm.  Another way of doing this which gives the random song feel (even though there is no random playlist option) is to add enough songs to the loop that by the time the show ends, the loop has played only once. 

I guess then it's fortunate that Spectrum's scheduler works for you.  I never successfully got it to run my shows even once.  Spectrum was certainly a fancier program, but for a lot of people, it simply didn't work.  Aurora by contrast is a much simpler program, and as such it works for more people because there is less that can go wrong.  I too would like to see Borealis have the capabilities that Spectrum's scheduler did, but I'm more interested in having it work without error than I am in having it full of features that crash the program every time I try to use it.  I'm sure that next year new program features will be implemented.  Check back then to see if anything has changed. 

Good luck with your show.
