Hi. I am using a bunch of buttons that will work fine over wifi using the code below on a esp32. Actually I deleted the button code to make this easier. I am sure I am just not thinking of something simple. Buttons, like the potentiometers, are asked to constantly listen for changes. But buttons aren't constantly in a state of slight deviation every listen... so they send tons of messages and slow everything down... the other buttons and my Ableton Live set. Is there any way to somehow write into the code "if variation in value is within +/-3~ values, don't send a message?" I am using these to control numbers 1-127 of their controls (knobs in guitar rig, levers in LIVE, etc.). There's got to be a better way to code these that make the pots calm TF down. Lol.
