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.
