>  With osc (hard) sync, the slave osc wave is constantly reset so 
that it starts its wave cycle at the same phase point as master osc 
wave. As a result, slave osc wave becomes more complex than 
normal,adding harmonics to the sound. Changing pitch of master osc 
changes pitch of overall sound. Changing pitch of slave osc changes 
timbre of overall sound by altering harmonics; for example, using 
filter envelope to mod slave osc pitch to get that Cars "aoww" sound. 
I'm not sure what goes on with soft sync (Ion has both hard and soft 
sync,and choice of sync to osc 2 or 2+3.) Sometimes soft sync sounds 
like it generates harmonics an octave lower, but I'm just guessing. 
Between sync and FM,(and ringmod) you can get some pretty wild 
sounds...
