<div>There's a really simple, few parts VC Clock that John Blacet wrote up for Synapse magazine Volume 1 number 5 (January/February) under the title Walking Ring Sequencer. Uses a 555 and a handful of parts. You can find it on the Cyndustries website ("Goodies" link ). Maybe not good for what your trying to do, but could be usefull to keep in mind.

Are the 4 pots changing the length of the sequence in any way, or the notes themselves? (Trying to remember what the 7474 TTL chip is - as I tossed ALL of my TTL, a few months ago. :( (Google - AHhhhhhh, a FlipFlop. :) )
<br></div>I'm not partial to regular 555s though, with all of the current they're pulling and the noise they cause. :(<br>But the other day - in searching for VC Clocks, I DID find the 4069 one from Renč Schmitz. :) I really like the look of it, as it's tiny as heck circuitry wise. :D I'm just about ready to cook the 1st PCB for my sequencer, but I still have room on the copper for another board. So I MAY lay down the 4069 VC Clock as well. :)
<br><br>Thanks anyways though. :)<br></div><br>-- <br>Take care,<br>Warmth and Peace,<br>Ryk<br><br><a href="http://deathlehem.bravehost.com/damian.html">http://deathlehem.bravehost.com/damian.html</a> - D.A.M.I.A.N.;s webpage - Dec 2705 update
