We have studied large, heterogeneous populations of discrete chemical oscillators (~100,000) to characterize two different types of density-dependent transitions to synchronized oscillatory behavior. For different chemical exchange rates between the oscillators and the surrounding solution, we find, with increasing oscillator number density, (1) the gradual Kuramoto synchronization of oscillatory activity or (2) the sudden quorum sensing switching on of synchronized oscillatory activity.
