I’ve been working on a sequencer for synths and circuit bent toys using the 4017 decade counter. These IC’s only count up to 10, but I wanted a 16 step sequencer, so after a lot of head scratching and sleepless nights, i managed to cascade 2 of them to give me the 16 steps.

For some reason the suggested circuit in the datasheet for the 4017 didn’t work the way I think it was supposed to, nor did any of the other circuits i could find. It would seem that a bit of hackery is required to get this circuit working.

more later.
