[sdiy] VCO reset time for BBD-based PM

I'd say that's ok - just so - for an audio VCO.

But once you want to clock a BBD for making a Physical Modelling oscillator,
it looks pretty bad. With a BBD length of 512 stages, you're already in the
1ns
range of reset time for the accuracy quoted above. Or use some compensation
method and longer reset times.

Re-introducing Harry's dreaded BBDs into the thread (;->)
But I'm serious about this application. So who makes a HF VCO that goes
up into the MHz range and keeps the tracking error in the ns range ??
HF compensation allowed, PPLs not allowed.
