[sdiy] "Living VCOs" PCB in 2009 ?

[nicolas]

It is interesting from a synthesists point of view isn't it.  I think what he is saying is that when the piano strings interact with each other through the bridge there is a tendency, if they are perfectly in tune with each other, for them to sync with each other, but 180 degrees out of phase.  Hence diminishing the sustain.  In the synth world unintended syncing between closely tuned VCOs is also a well known problem, but the syncing tends to be in phase rather than out of phase, so the audible effects are different.

Cheers,
Nicolas
