Mixing live with a MIDI controller?

hi everyone !

i been Djing with the Nocturn Novation Controller and i wanted to make a whole track just automating the mixer channels and sends with my controller . like a dj mix pretty much . i did some experiment with a 32 bar loop. and i was very surprised that jamming and automating the controller i got great results . but when i wanted to move on further i felt that the track felt to Live ( i mean there was many timing errors ) . I mean it is seemed that too much was going on with the track and felt bored. did anyone here mixed a whole track like this ?

should we edit the automation to make it sound on timing or is this not nessesary if it sounds right?.
