I'm not sure there's too much you can do with it calibration-wise -- with those chips most of the calibration is done dynamically in software, so there's not much to adjust manually.
For what it's worth, the ROM of the Split-8 needs a complete and total re-write. It was a one-off created by the japanese company that worked with Sequential, and between the terrible UI and the latent keyboard scanning, I had to ditch mine. I just couldn't use it as a playable instrument. The sounds are really cool, and perhaps it might be more useful from an external sequencer or midi device, but it was too disappointing the way it is. Kind of like the Roland JX-10. Awesome hardware, terrible software. Wine Country also sells complete schematics and manuals and parts for Sequential instruments. -pc

Playing a scale on the keyboard shows a couple voices are now out of tune and running the front panel auto tune doesn't bring it back into correct tuning most of the time and it will drift off pretty quickly. Has anyone calibrated a Split 8 and can anyone point me at schematics or documentation on calibration?
