Split the keyboard, with the bottom half panned hard left, the upper hard right (well, maybe not as hard as that, but more than 50% at least...). Pan the bass to the middle, obviously. Ideally, of course, this 'sharing' of the frequencies should be done when the song is composed and arranged, so as to have a better sonic field for each instrument, although there's no absolute rules for this, either. Some overlap can be musically valid, it depends on the song.
Kudos for the drumming in the video; more interesting than many 'young' bands these daze. All in all, Good Stuff, worth getting right 'live'.
Hope this helps.
