[sdiy] crazy CMOS behavior

[mark verbos]

I have built a sequencer based on the 4516 counter. The clock input is 
stolen from the Serge TKB schematic that is on music machines. That is, 
trough a cap to an NPN then a CMOS inverter then to the counter. When I 
clock it, with anything, it jumps all over the place with no real sense 
or pattern. Could this be related to the step length not being right? 
How does it work for the actual Serge? It's not the chips, I have 
switched them all out and it does the same tihng. Am I just missing 
something not grounded or something?

thanks for any ideas, I'm going nuts here.
