It seems there's a SID WIzard 1.7 and SID Wizard 1.7 patched for Kerberos. Of course there's no real way to tell and the 1.7 which wasn't patched was the one included on the Kerberos cart. Once you download the latest SID Wizard 1.7, the MIDI menu will give you a "Namesoft" option which solves note triggering issues. The Kerberos manual says to use the "DATELJMS" option which doesn't even remotely work. Of course none of this is documented.
Having said that, after updating the note triggering lags, the SID WIzard playback kicks in a full half second after the sequencer sends a MIDI start command and there's no MIDI sync. Extremely frustrating.
