  We report on the impact of a probabilistic prescription for compact remnant
masses and kicks on massive binary population synthesis. We find that this
prescription populates the putative mass gap between neutron stars and black
holes with low-mass black holes. However, evolutionary effects reduce the
number of X-ray binary candidates with low-mass black holes, consistent with
the dearth of such systems in the observed sample. We further find that this
prescription is consistent with the formation of heavier binary neutron stars
such as GW190425, but over-predicts the masses of Galactic double neutron
stars. The revised natal kicks, particularly increased ultra-stripped supernova
kicks, do not directly explain the observed Galactic double neutron star
orbital period--eccentricity distribution. Finally, this prescription allows
for the formation of systems similar to the recently discovered extreme mass
ratio binary GW190814, but only if we allow for the survival of binaries in
which the common envelope is initiated by a donor crossing the Hertzsprung gap,
contrary to our standard model.
