Unfortunately i haven't used the stock meterbridge. Anyway i quickly made the sdk module with assignable numbering.
You have to connect it manually though.
If you don't find it useful delete it.

About the possibilities of the sdk and the "dx-7" of course the discussion is not serious.
A DFM engine is perfectly feasible, but one should design the sine oscillators from scratch
because there is no sine oscillator stock atom with phase modulation.
I have done it. Of course i made it in 2015 which means 10 years after i started using the sdk.
The Fm oscillators of the sdk and the modular are very good and the timbres created with FM and DFM are pretty close.
About the " a good harmonizer/chorder/pitch shifter would be cool".
My opinion is that a pitch shifter algo to work right is not an easy job.
I have created such a device but unfortunately i can't share it for free.
