In the schematics there are two controlling signals: the signal 'Sync' 
enables the reset of the programmable counter of the slave DCO. The 
signal 'Met/Syn' enables the reset of the integrator of DCO2 by the 
counter of DCO1. I never checked that in the real synth, but considering 
the naming of those two control signals it is most likely, that sync 
causes a reset of both, counter and integrator, while metal causes only 
the reset of the counter.
