This is a simple analog step sequencer with 10 steps. It’s loosely based on the Baby 10 Sequencer. It generates 10 different control voltages (CV). In the background you can see the Simplesizer, a simple analog synth which I built recently. The sequencer controls the synth via CV. Gate/Trigger is in the planning but not functional yet. The circuit of the sequencer is actually quite simple: A 555 timer IC generates a pulse signal which acts as a clock signal for the 4017 decade counter IC. Between the steps you can hear jumps in the frequency. This is because there is no voltage regulator. Maybe I should add one to the circuit. But I think it sounds cool anyway. Schematics can be found here.
