Ok, for the FM part you at least can set the phase offset. I agree that 
having that modulateable would be quite some fun. Regarding modulation 
complexity, the SY77 isn't very modulateable, so having the phase offset 
modulateable would certainly call for 1-2 more LFOs and EGs to make this 
somewhat useful.

However, the strict phase reset does not only apply to the AWM voices 
but *also* to the LFO, the latter of which being just plain annoying.
