6 track mixing board should be the standard. When layering and layering and layering and layering a production. You can compare it to eating a sandwich. The more that's added the more it's hard to consume & digest. (Imagine) What if a speaker had a stomach? I'm sure if it intakes massive sound bites......it will end up with irritable bowel syndrome causing cramping-bloating then exiting out thin. AKA Diarrea. 💩👍🏼
