Sync PO with Control Voltage (Stylophone DS-2)?

tl;dr What’s the simplest (…or cheapest, or “best”…) way? TIA.

(Apologies if this has been covered before. I’ve read various - slightly contradictory - things, and I’d be grateful for some clarity. Thank you).

I’d like to use a PO-33 as the master, and sync the LFO of a Stylophone CPM DS-2 (this) to it.

In theory, I think I can just:

  1. connect a splitter cable (1 x 3.5mm stereo to 2 x 3.5mm mono) to the output of the PO-33

  2. connect the “sync” channel of the cable to the “LFO RESET” CV in of the DS-2

  3. select an appropriate sync mode (1, 3 or 5) on the PO-33

  4. press play

But I haven’t tried that, because:

  • the signal levels look kind of wonky (Vpp of PO sync is between 0.6V and 5V; CV IN on the DS-2 is between 0.7V and 12V)

  • I’m wary of damaging either device

Has anyone tried this? Does it work?

Alternatively, should I just buy (e.g.) a Korg SQ-1?

Advice gratefully received; thank you.

the actual sync signal that the PO spits out is notoriously low

i think like somewhere around 1v?

so u may run into issues depending on what’s on the receiving end

one way to remedy this is to use something to amplify the sync signal
