Note that one library contains the same bank under 3 names Cart4, Ray-1 and RayGenre: Various. Banks in orange are unique contain only unique voices. Banks in blue are those with more than one copy selected has five.

Voices in orange in the left pane are unique 1 copy in the full archive. Note that the same voice is stored under various names in different banks. Screen shot of librarian showing all copies of the voice selected. It took a bit more time to build than I anticipated I did it on perfbord with the component leads providing the connections between partsbut now that it's finished I actually look forward to tediously calibrating all the oscillators.
Two LEDs on the front panel show proper connection to both negative and positive supply voltages. The calibration tool's power is taken from the synth's power supply. Incidentally, I get the top 7 volts by simply swapping the 47k and 68k resistors in Ray's circuit trimmed to precision using a 10k multi-turn trimpot. I don't know how that difference translates to resistance, but in any case they all now seem pretty equal to me. I managed to find two groups of 3 and 4 resistors that among them produced a midpoint voltage of 0. In contrast to Ray's tool, mine spans a 7 octave range by supplying voltages from 0 to 7 volts.

Or, if you can't be bothered, you can go to Bobby Blues' All the Web Patches Collection where apparently he assembled and zipped into a single archive all DX7 voices that he could find on the web. For the rest of us, there are DX7 voice banks galore that can be googled and downloaded from all over the place. If you've got a Yamaha DX7 you know that it's a nightmare to program, perhaps unless you've got one of these.
