[sdiy] How to avoid clicking gates

Well, I triggered the sync and patched a string bass-type of sound, and the
difference was barely perceptible, and only at the very lowest frequencies.
However, I can see how it would be important for bass drum-type sounds.  In
addition, if one is using an oscillator for LFO applications, and wants to
start the LF oscillations at the same point with every note, then triggering
the sync would be useful for that as well.  In any case, it is an easy to
do, so I'll keep doing it.

One thing I discovered while playing the string bass sound was that, if I'm
sending the keyboard CV to the filter cutoff as well as the oscillator, then
if the oscillator's tuning range is adjusted, the filter's cutoff must also
be adjusted to maintain sound quality.  Another good thing to know...

Aren't these damn things fun?!?!?!?
