You will only hear anything if you are actually changing the pitch of an 
oscillator.
Sync works on the principle of locking harmonics of one oscillator to 
another. These changes will only be heard if you modulate the oscillator that 
the sync is latching to (or is that the other way round??)- Sync produce that 
(IMO) horrible 80's sound- to get screeming lead type sounds. But it can be 
used subtley to create other waveform timbres. What this function does (the 
parameter you describe) is link sync with FM- for all matter of "sounds from 
hell"!- Carefully used, you can get some wonderful DX100 type noises- but 
remember, the FM on the AN1x is very basic- and is not algorhymic- unlike the 
DX series.

I hope this has answered your question!
