[sdiy] 4017 sequencer

[daryl groetsch]

I'm working on a 4017 sequencer (actually a 74HCT4017N, all i could find 
locally). It's very basic, clocked by a 555 and each number output 0-9 
has a 1K pot on it, then to a CV jack. I'm running it on a +5V computer 
power supply. My problem is when I change the pitch of a step, the pitch 
of others are affected. All pots and jack are grounded, and I've tried 
various VCOs.

Also, even with bigger pots the pitch range is about 1 octave. How  can 
this be increased?

Thanks much in advance!
Daryl
