Hello Paul:

First time I heard about this machine.

Schematics are here: http://sounddoctorin.com/synthtec/sci/split_8_SM.pdf

Best regards.

Assunto: [vintagesynthrepair] Sequential Split 8 Tuning /Calibration/Service Docs

Hello All:

I just replaced the battery in my Sequential Split 8 and reloaded the sounds but I now find for the first time since I bought it new in 1985 that it's having lots of tuning troubles. 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?

Thanks,

Paul T
