Re: The 4OP to DX7 Conversion Project

It's all a matter of try and see.? I started out in the FM world on a DX9, with its four sine operators.? It wasn't a DX7, but it got close, in many cases.? I can tell you that I missed velocity sensitivity far more than I missed the extra two operators.

I think it wouldn’t be easy to get from the pair of operators a timbre missing in the total sound of the patch. But maybe additional tweaking of the other four operators in algorithm structure simulating 4OP patch, in conjunction with those two operators can make it…

I'm now meditating about the other interesting challenge - to imitate 6OP sounds on 4OP synth, at least on those able to layer two patches… :-) It would be difficult if not impossible to approximate non existing algorithms and key scaling, different envelopes…

What I've always wondered is if there's a way to create those additional
waveforms using a carrier/modulator pair so straight sine wave instruments
could get in the neighborhood.

Thanks so much for your work on this!

A naive question: how, if at all, have you handled the additional
waveforms on the TX81Z/DX11?

Hi,

The additional waveforms that were introduced with the TX81Z are ignored. 
In general not everyting could be converted faithfully. There are quite some
bigger and smaller differences between the DX7 and the 4-op FM family of
synths. But I hereby invite everyone to do something useful and interesting
with the 2 unused operators that are left :-)
