Hi, raw midi files can be disappointing at first : it's because it's only the note, but not the dynamics, so it can feel almost robotic. i simulate dynamics with velocity to show you where to tweak dynamics. I play with tempo too, to slow down or accelerate some parts... I use arturia piano, roland galaxias, spire and many fx like vinyl, taip etc... it's a little work, but the secret is the dynamics, filters. For the drums you'll maybe have to move hats or snare from a column to another to match your drum in your daw depending of the kind of drum kit you use. MIDI is a great way for songstarters but it will need some work. Sometimes i modify some notes for the final output, add some lines or copy paste some movements... No loop samples were used. Lofi music need heavy effects, specific sounds, and inspiration ! Keep on !
