We will be looking at how we can use a heartbeat from StageCaller to automatically switch to backup recordings if the phone becomes unavailable and to have a second line of backup if the phone is working but for some reason, it can’t be heard. It assumes you have StageCaller set up and working correctly for basic operation (If you don’t, then skip to page 2 of this tutorial and we’ll go through how to set it up from scratch). This chapter is primarily about using all the features available in QLab 4.1 and later, to try to get operation of QLab and StageCaller as reliable as possible. It’s therefore wise to recognize that what worked perfectly in the dress rehearsal, in an empty theatre, may not work so well once the audience are in.
