I have watched his Masterclass from the Masterclass website. I remember things being kept pretty simple. But he and the 2 co-producers Angel and Fede that he works with, they bounce stuff along the way, so they get an instrumental loop and Timbo mostly applies his drums to. That loop is made up of many layers of sounds and layers of fx... I am not sure if they keep all original tracks to send them for mixing. Given the setup they have, I doubt it will work. But they have a mixing engineer present for the session at all time... And he mixes things as they add up.His engineer says he mist often don't even separate his drums when he sends them.
I would bet they don't use so many tracks, but a few tracks made of many elements mangled into them. And the mixing process makes plenty with tons of parallel processing and fx busses, sub-busses and what not.
Oh, and if you're wondering, they use ableton live.
I recommend watching that Masterclass if you have the chance. It's an interesting approach to beatmaking. It's really an office job at this level.
