You could also program a drone, noise, or simplified beat that keeps momentum going onstage till you switch banks. Youd know it’s the end of the song but your audience would be less likely to disengage. This way you only lose sound for the bank switch and setting up the next pattern chain.
Edit: you can also do this for setting up the next pattern chain. When you song is repeating the last pattern, you can select a new bank, your “intro” pattern and let it play while you set up the chain. Once you’re ready, hit stop then start on time and you’re into you next song. It’s all performance so good luck!
