Hi, ive also been casually working on designs for a sequencer for quite a while (too long!).
Heres one by the reputable dude casper electronics:
http://casperelectronics.com/finished-pieces/sequencers/step-sequencerI want one to trigger where the piezos normally would on my electric drum and so a volage pulse out is fine for me.
I was after more steps than the one above steps so ive tried (unsuccessfully) to cascade two 4017’s. A new thought occoured to me… maybe they could be driven by the two outputs of a darlington pair (flip flop).
This would’nt allow the 50% duty cycling thing done with the 555 (which might be a problem) but would be a nice tidy circuit! Perhaps though the square outputs could be turned into a spike, thus distinguising individual steps, using a capitor (a bit like in this post:

Any thoughts?... Also I dont know much about the 4016 in caspers diagram, is it working like a bank of relays in the circuit? Cheers!!
