AFAIK, Zeta+2 will only sync when it is used as a plug-on with a host. Without a hot, there's no temp for it to sync with. Once you've got your DAW and Zeta+2 open, there are different places to set the sync rate depending on what you want to achieve.
First, on the Synth page (main patch edit location) look in the bottom-left pane and you can toggle this between "mod" and "arp." The mod page is useful as can map 16 different controls to different synth parameters, but mods won't sync on their own. Switch to the "ARP" page and you should see "sync" is the second parameter. This will determine the arpeggiator rate as a multiple of the host tempo. Values range from OFF to 1/8th, but under each value, you can also select modifiers, e.g. under 1/8th you can choose 1/8d for a dotted value or 1/8t for a triplet. Note that you can also set the "mode" to free/sync/gate but for the effect that I
think you're after, sync might be best.
When you play around with this value, it might be best to start with a simple pattern such as up, down, or random as the more complex MIDI patters--cool as they are--introduce their own rhythm and it could get confusing.
Also on the synth page, you should see the "LFO" pane near the middle of the right side. Each of six low frequency oscillators (LFOs) can be synced individually. First select the LFO you want to work on, then change the sync value in the little table where you also select the LFO wave type and the mode. Same idea here, sync in the same way you would the ARP.
Finally, you can also sync effects. Go to the second main screen (choose EFFECTS near the top close to the preset selector) and you'll see that time-based effects (modulation and delay) can also be synced to the host using the same technique.
There are more ways to set sync than most other synths, but each patch, each arp patter, each LFO combination, nd effect will produce different results. Dig in and experiment.
