Modular Synth Panels

I built two last weekend, but just got them working yesterday (had to
wait for replacement parts to be shipped).  No problems with the
circuitboard, just parts selection.  Seems that not all 4046's are
created equal... stay away from the 74HC4046 and go with the CD4046 -
maybe this could be included in the parts list... I had no prior
experience with this wacky chip and didn't think to check its power
requirements.  Other than this, no problems - I'm amazed I managed to
solder all those surface mount caps without shorting or smoking any.
Are they really required?
