The Groove / Swing

Hello everybody! I’m new.br
br
I’d like to know how everybody creates the groove/swing of their tracks.br
br
Do you play a midi controller and leave it as it is? Do you use groove/swing emulations (presets), such as an emulation of the MPC groove?br
Do you mix quantization with a percentage of such an emulation/preset or self-created swing?br
Do you try to use the same groove for every part of the song, even the harmonies/melodies/bassline?br
Do you do it from the start or at the end?br
br
I hope everybody knows what I mean.br
I am very curious about everybody’s technique…
