I see your point and yeah I guess that is true. I was always one to be a fan on the old stuff and always diverted myself away from the new and hot joints coming out now. I definitely stay away from this trap faze that is going on right now at least thats for sure.
Who knows man, I mean even the most relevant cats in the business are MPC users (Yeezy, 9th) as well as the up and coming or already hot producers right now like Araab, 88 Keys.
This is just my opinion, sure the masses will in general prefer a portable on the go type of machine that will do the trick, but these big shot producers no matter what their relevancy will keep their MPCs and use them in their $100 000 studios. Just my prediction for the future.
