Wonderful stuff.
I think the idea was that when the master oscillator is modulated with an
LFO,
the PLLs would respond with a different delay / phase shift each.
Never tried it, but it might be well worth the effort to get rid of phase
lock
during modulation transients, and still have stable frequency ratios.
