[PD] linked-slider logic

         I'm writing a really simple delay abstraction with separate delay 
times for the left and right channels. But I've included a toggle to 
control whether the left and right sliders are linked, so that they are 
both set to the same value. The thing is, I can only really simply 
implement this when one of the sliders is the controller, and the other one 
the slave, otherwise I get a loop going if I let them control each other.

         Has anyone implemented this kind of logic into their patches? I'm 
sure it's pretty simple. I can sort of think of detecting which slider has 
been moved and then using some spigots to route the information from the 
moved slider to the other one... But I'm having trouble visualising exactly 
how I'd go about this, especially if I want the user to be able to drag 
either of the sliders.

         Any help would be super appreciated.
