Mike's trick then is to take a snapshot~ of the original phasor at the moment of the desired phase resetting. If you substract that value from the original phasor, you get a phasor~ shifted up or down just by the value it had when the phase was last reset.
Now you can add in the desired phase value again to get a wrap-phasor that is out of sync to the original phasor in exactly the desired fashion.
Actually I meant two write "take a [samphold~] of the original phasor". Taking a snapshot~ or rather, a vsnapshot~ is something I have also tried, but it gives the wrong results. See attached example for a comparison of [vsnapshot~]->[vline~] with Mike's [samphold~] solution (which I simplified a bit). Lesson to learn: [vsnapshot~]->[vline~] won't do what you may expect it to do.
