Hi Ollie, yes the article that Krinor posted will give you the specifics, but basically it's CV/OUT and GATE/OUT on the 'sending' synth to the CV/IN and GATE/IN on the 'receiving' synth. You may need to buy 1/4" to 1/8" 'mono' patch cables from Radio Shack (or whereever) to go from, say an SH-101 to an SH-09. Good luck, and let us know if you need any more help! CV/GATE RULES!!!
