well..... yes.
I dont claim to be an expert on every form of osc sync known to man, but
the most commonly found flavour, "hard" syncing, is produced by using
the outpot of one oscillator to retrigger the other oscillator.

now, whenever osc 1 reaches the "start" of its cycle, osc 2 is reset to
the start of its cycle. When the 2 oscillators are detuned from one
another, you get osc 2's wavelength being some fraction of its original
wavelength (same as osc 1's wavelength, ie same pitch) but the
"waveform" will be something like 1.1 or 0.7 or 2.8 cycles of the
original waveform. You use it in pretty much the same way as PWM. Its
most effective when you try pitchbending osc2 while its synced to osc1,
rather than just leave it set at whatever ratio.

Now, I've also heard of "soft" syncing. what the hell is this?
anyone?
