Didn’t find that to be dismissive at all!
I realized this am that the min max values was a problem. If both the accums were reset at the same time the phase relationship would change.
Changing the accum to a + .05 -> modulo 1. works, and you can reference the unshifted ramp from it’s output. (or from the mute ramp which is resetting the ‘phase’ of the main ramp).
Hope this helps! it seems like its on the right track anyway..
