If you ever wanted to humanise MIDI clips on the fly, check out Group Harmonizer by James Holden. It's a pack of Max for Live MIDI effects that allows to affect the timing of multiple MIDI tracks at once.
Let's say you have a bass and a drum sequence. With Group Harmonizer they will adapt to each other's delays in a humanised way. It implements the method of group humanizing MIDI described in the article by Holger Hennig, "Synchronization in human musical rhythms and mutually interacting complex systems" in the journal PNAS (2014).
