I love Bartons modules and have built some of them, from “complicated” with preprogrammed PICs to simple ones like the dual A/R.
However I recently noticed his latest module, a 8-step sequencer with four outputs where three were clocked differently (/2, /4, /8).
His simple and elegant sequencer was a perfect starting point for one idea to come true. Not knowing if it is a bright idea or not, I want a 3-4 output sequencer where the outputs are delayed a number of clock pulses.
Barton clocks four analog multiplexers differently, but I simply shift the potentiometers two steps to the multiplexers and run them all at the same clock frequency.
I am using an experiment board for the four CD4051, an up/down counter (the module will have three inputs - Clock, Up/Down and Reset) and two TL072s to buffer control inputs and VC outputs.
Here’s a first sketch of the module. As I lay sleepless the other night I found out that I hade arranged the potentiometers the wrong way around.
Will temporarly postpone this project as we are going to Belgium next week.
Any ideas?
