Now, the scenario could be changed. Infact the video will not probably run more on a used U-matic gear, but on a DVD player; so I was thinking of the chance of record on audio tracks some ultrasonic material (so not audible) which could function as a trigger for the various oscillogram events. This would save money of the syncronizer. Would it be effectively manageable? Any help appreciated F. -- MUSICNET STUDIO di F.
