Typically, when using strong sync this jack would be an input, and would be
connected to another oscillator's waveform output jacks.

But when using weak sync, you would set 2 or more oscillators to weak, and
connect them all together using this jack (and mults if necessary), so it
then becomes an input/output jack.

For those not familiar with the difference in behavior between hard and weak
sync, here is an explanation:

Hard sync is the sound you heard a lot in the 70's and 80's, it gives a
distinctive growly sound when you sweep the pitch of an oscillator that has
been hard synced. Almost became a cliche, like the swept resonant filter
sound. What happens is that when the waveform of the "syncing" oscillator
resets, it forces the waveform on the "synced" oscillator to reset also.
Good for creating new harmonics in the waveform.

Soft sync is seldom seen except in modular systems. It causes oscillators to
lock into tune and phase as their pitches approach a mathematical ratio. You
can get perfect suboctaves with no beats, etc. If you sweep the pitch of an
oscillator that is soft synced, it tries to jump to the nearest pitch - not
quite quantizing, but a cool effect.
