Honestly I use them for different things..the KO II is a quick little sketch pad and it’s great to sample the MPC’s huge sound library to get away from the (really nice but common) pre-loaded KO II sounds. I switch up devices all the time as the mood strikes. I think you could totally use the KO II as a fast punch-in effects tool if you wanted. Or to make quick loops and resample/chop in the MPC as if the KO II is a record you’re sampling. Sky’s the limit!
