[sdiy] din clock variable shuffle

[Frédéric Bourgeais]

Hi greg,

Nice idea, Ive done this step sequencer,
http://www.synrise.de/diy/sequenzer/sequenzer.htm

I needed a Din sync input to connect it to my midi gear via a midi-din 
clock converter. I used the ken stone method, using one 4017 for the 
division. Cheap and easy, it works very fine !

Took a look his excellent Pulse divider & boolean logic:
