16 Step Up/Down Sequencer

This is by Dr. Offset

"At some point in every DIY Synth enthusiast's journey they realize that they need some sort of structured way to control all the madness they've created. You want to build a sequencer. Often the first type of sequencer you build is something like the Baby 10, a ten step machine based off the 4017 decade counter chip. That's fine, and a lot of people do great music with it."

Mini Lunetta Patched Close up

CMOS-based instrument designs have earned a strong following among the synth-diy crowd - and for good reason. The circuits can be relatively simple and the resulting sounds quite interesting. The Lunetta is built primarily from 4000 series CMOS integrated circuits with inputs and outputs taken to front panel jacks to be patched to other sections.  Lunettas uses counters, shift registers, XOR gates and 40106 schmidt trigger clocks and oscillators.
