The first sequencer I ever built. A 10 step analog sequencer based on CMOS chips. A 40106 generates the internal clock signal. A 4017 counter distributes the clock. A switch for internal or external clock signal. To achieve a clean step seperated Gate signal, I use a 4081 Quad 2-Input OR/AND Gate.
I used the following schematic: http://www.midiwall.com/gear/babyseq/ |
