SCI Pro-One overview
(The red power LED on the upper right above the Master Tune knob is a modification)

Finally I own this well known monophonic 1980 synth. Although a stick tell it is out off warranty since the 4th of October 1981 it playing fine thanks the faithful repairs and calibrations done by H.S.

SCI Pro-One back

The Pro-One features these connections on the back:

  • audio out
  • audio in
  • filter CV in
  • gate out
  • cv out
  • gate / ext. clock in
  • CV in
The powercord is not detachable :-(

I installed the Pro-One Keyboard Replacement Kit to get a quit and even more reliable keyboard action. Easy to do kit that just needs screwdrivers to install.
