Micro tuning isn’t possible on standard DX7 Mk I, but it’s possible with some third party expansion cards installed.?
DX7S, DX7 II D/FD, TX802 (Full keyboard), and 4OP synthesizers of DX/TX and V series can be retuned (Octave and Full keyboard on 4OP instruments). Resolution is 1024 steps per octave (1.17 Cent per step approximately) on 6OP synths, and 768 steps per octave (1.56 Cents per step) on 4OP synths.
Micro tuning is also on later instruments - SY/TG77, SY99, VL1/7 and other… EX5/7 have only preset tuning tables. XG instruments have only limited micro tuning - Octave, with retuning range of each 12 tones +63/-64 Cents.?

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.
