Please keep in mind while emulating the sound of DX7 you also have to 
recreate the behaviour of the D/A converters which had a huge impact on 
the sound. For instance the DX7II sounded different than its precursor. 
I don't know about the legasynth nor about Franks approach but it takes 
more than just recreate the FM structure and sysex compatibility. Its 
the same with other simulations, you can't stick a sawtooth generator to 
a filter in PD and claim it to be a faithful analogue simulation, lot of 
subtle details are missing.
