16 step sequencer schematic

After a lot of searching the web, I could not find a 16 step sequencer schematic that didn`t require an arduino or PIC or some other digital controller. Here is a simple 3 chip analog 16 step sequencer with variable speed and arpeggio I came up with, based off many other inspirations as noted in the file. The I

Cs in the middle are pin-diagrams, arranged like this since a 4015 is actually two 4-bit shift registers in each chip, so each 4015 has 16 pins but the IC numbers indicate IC1 and IC2 (IC = integrated circuits, AKA chips. ) If you`re new at building sequencers, make sure to learn how to tell the polarity of capacitors connections and the way to figure out pins. Check my other illustration ( 8-step sequencer ) for diagrams and other important parts listed of a fully functioning machine. For example, the CV output pot and plugs are described in more detail on that schematic but not here.
