The synchronizer XRI XR300 is a great product at SMPTE code generation, 24 or 25 frames, useful for synchronizing such a magneto and an analog computer in MIDI or Audio, or analog video recorders to synchronize them. I used it for over 10 years but the arrival of a large audio sequencer that I do not use any longer. The response time is excellent, but the programming of the number of measurement is a bit laborieux.Cependant if anyone has one, I advise him to keep it. Anyway, if I had the choice to do so would be no problem.
