Hi Charles,

Welcome to SDIY and congrats on starting a synth project. Here are a few
links to simple sequencers that I've found. Take a look and see which you
like best (or maybe even use bits from all of them). Have fun!

Ray Wilson's expandable 8-step seq
http://www.musicfromouterspace.com/analogsynth/sequencer.html

A couple of interesting circuit bending/sequencer ideas
http://www.sailormouth.org/cbender/seq.html

Ken Stone's Gate Sequencer (also use the CV Adapter add on in the next link)
http://www.cgs.synth.net/modules/gate_sequencer2.html

http://www.cgs.synth.net/modules/cgs42_cv_adapter.html

John Blacet's really nifty MIDI to Sequencer Clock chip! Includes a few
simple schematics for application ideas.
http://www.blacet.com/MSdata.html

The Mooseq; a rather nice and very simple circuit. Includes switches for
switching the glide in and out, a.k.a "slide" feature. Also has one of my
favorite URLs ;)
http://undershorts.org/espresso/mooseq/

A fairly simple 16 step unit from the SDIY network. Uses the 4067 1-16
analog MUX.

Again, have fun with it and don't hesitate to ask questions. A lot of the
authors of these schematics are on SDIY, and I've found this to be a very
helpful list (even if you have questions about BBDs!).

Cheers!

Tim (waiting for the coffee to kick in) Servo
