Summa,
 I was a bit brief in my description, and even mis-spelt the subject line!
I should have been more succinct!

On the Tx802 the paramater is called Oscillator Sync, and it's called that on a Dx7 and a IIFD as well. From what I've observed in my use of the oscilloscope and recording Waves onto the PC, it sets the phase of all operators to 0 degrees when a new note starts. I played around with it for a while, and couldn't make a patch that made much difference in the sound, except when I used more than one low frequency Fixed Frequency wave in a 2+ depth feedback loop.

 I know about using oscillator phase and setting the initial phases of different operators/oscillators in synths (sadly, something you can't do on any of the Dx series instruments),

I can only guess that you mistaken the Oscillator Sync with the Oscillator Phase
parameter and even that parameter makes a difference in conjunction with FM-
