There¡¯s nothing like Fractional Tuning. Yamaha calls it Full Keyboard Tuning.
Besides Octave Tuning DX11 can do Full Kbd Tuning as well as DX7 II D/FD, DX7s, TX802, TX81z, WT11, V2, V50 and some later instruments. So all of them can use Stretch Tuning.

I've been reading about the "Railsback curve". Is there a way to implement this on a DX7?
For those not familiar, this refers to deviations to the mathematically pure 2:1 ratio for octaves that are often implemented by piano tuners. I'm curious about this, in part because of intonation issues when playing my oboe along with recorded DX7 parts. The higher notes of the DX7 sound progressively flatter compared to what I'm naturally playing on my acoustic instrument. I've been working to adjust my acoustic instrument's pitch to accommodate, but from what I've recently been reading about "subjective octaves" (that for orchestral instruments, they may in fact have a stretch-octave curve similar to the piano's Railsback curve), I'd like to experiment with having the DX7 accommodate my acoustic instrument, instead.

I have a chart in a piano tuning book that shows stretch tuning.
Well, maybe I do. ?It's buried somewhere.

Hello?All,
FWIW, I just found some tables that I did decades ago regarding alternate tunings on the DX11.
One limitation of this is that these tunings apply?uniformly in all octaves i.e. they are not?¡°fractional¡± tunings.?
I suppose that you could layer different octaves to make a?¡°polyphonic¡± voice ¡ not sure if this approach would work on the DX7s though. Please find attached two such examples.
Greetings,
E?
