Aaron, what are you actually asking? Are you asking about the content creation, the content playback, the content delivery, the reinforcement systems or all of these?
What is your role? Are you an organizer of the event, a participant, a content creator, someone being paid to design or install the system?
Sorry for my lateness. Was in England with little wifi. These are all brilliant answers, folks. Thank you all Very much for your input on this.
I can create all the musical content that goes into the multiple tracks and how the need to be musically aligned. I've been trying to learn about how to achieve the perfect playback and delivery of these parade tracks for smaller venues.
Thanks again for the brilliant input and photos on the subject. I have a feeling this thread will be useful for some time to people looking for these answers as they are very difficult to find. I used to perform in parades at disney and universal and I can tell you that No One every really knows how the parade works. They all think it's from, and I quote, "a big computer somewhere", and that's it. Magic big computer. When was the last time you actually saw "a big computer", hahaha.
