Scott, 

 I realize this is not really "synced", but if you have any midi to trigger converter and an LFO with Sync In, you can get a similar effect.   It requires a but of fine tuning to get a perfect cycle this way.  Another thing you might try is using a trigger/gate pattern and a Slew Limiter of some type, as your trigger pattern can certainly be synced (again, assuming you have some sort of midi to trigger converter). With the top half of an A-170 Dual Slew you can get something resembling a sine or parabolic. With the bottom half, you can get ramp/saw shapes if your gate is long or short enough.  

What do the rest of you think  I'm at work so can't test it, but it should work, in theory....  I've done patches like that before, but I too have an MCV-24.
