One, thanks to everyone for the encouragement on this one.  You never know how things 
are going to go over sometimes and I aim to please.

sort of kind of, but it's not going to give you any sort of decay envlope - only gates.

A word about the PHASE LOCK:

Why didn't I just call it an external clock input? 
ext frequency going into it from the outside world is metric (constant pitch) then it'll track 
it just nifty.  If it has musical accellerandos and retards, it'll track that nicely.  But if you go 
from reeeeeeal fast to 1 beat a minute in a microsecond, you may find that it's slow 
reacting becasue it needs two taps to determine a change in tempo as it reads the interval 
between -and- it keeps the last read's tempo playing until it gets both taps. That's when it 
updates the output tempo.  So if the second tap is 1 minute away, it'll keep bopping out 
the last tempo it settled on, even if that was 48 hertz.  Takes some getting used to, but 
this was the bet way to assure accuracy for both the manual tapping and external input.
