Minim library, code I'm using is deprecated

I am a complete beginner with processing, and am using it to act as the brains for a circuitry project I’m working on. I found some code that uses the minim library, but it is old code, written for a different version of processing. I keep getting warnings that some of my lines have deprecated. I’ve looked to try to find the new correct way to code the actions I need, but I’m at a loss. Any help would be greatly appreciated!!! I’ve included the lines that say they have deprecated (they are not in order or context of their other code, so please let me know if you need more context on any of it). Thank you so much to anyone who responds to this!!
