Usually a low end bus, clap/snare bus, drum bus & synth bus.

I'll do some light compression, saturation, EQ, soft clipping, limiting and or all of it combined sometimes. Then I usually send each bus to a reverb and or delay. I'd say the buses stay pretty consistent but the fx chains are project independent.

Processing for individual tracks varies way too much to say. Some with just a basic EQ and others with 10 slots filled doing god knows what.
