Changing the PLL to be more loosly following, laging in tracking and ringing in
responce could very well be really usefull in musical applications. For those
eager to test such stuff out, using a 4046 and some divider is really a good
place to start. The PLL as mechanism is underused IMHO. Both in their strict
locking form as well as their looser "misbehaving" form. Maybe it's time to
make a generic PLL module for people to play with?
