unfortunately it is not that easy. You need to "OR" the sync out-signals 

of the polyphonic VCOs to get a proper signal for the sync-in.



As first test you may use a standard polyphonic synth which provides 

manual pulsewidth control. Set the pulswidth to the hearable minimum and 

then feed the sync in of your VCO-Module with the signal from that 

polyphonic sound.
