Clock a track via CV input while other tracks are normally clocked?

I suppose that to address the periodic resynchronization need, one would also want a reset in, tying up yet another limited and valuable input, or perhaps an FX function executed on another track, or similar. Yet more complexity.

Hmm. That gets me thinking of something... Is there an FX function that causes a break on a different specified track? Maybe even a break-like function but at the level of islands?
