10 step LED sequencer

"An LED sequencer circuit I built and modified to trigger the drum pads on a Yamaha DD5, allowing you to program your own beats and control the tempo. diagram and tutorial are at circuitbent dot wikispaces dot com in the advanced bending section."

    wikipsaces.com takes you to a domain spam site or whatever it is called...

    The 8 or 10 step sequencers are very easy to make with basically a 555 timer and a 4017 decade counter. BUT...I haven't figured out a way to make a 16-step sequencer by cascading two 4017s. If anyone knows how to do this, please enlighten me (and I'm sure a lot of other people would like to know as well!)

    I had planned on putting a 16-note sequencer into one of my circuitbending projects, but I couldn't get over this stumbling block. I didn't want to have just 8 notes, so I abandoned the idea.

    thanks for the link!
    as for 16 step sequencers, check out this link http://ourworld.compuserve.com/homepages/Bill_Bowden/page5.htm

    which has a bunch of schematics, maybe one will be of use to you (i'm not so good with all that)
