Eurorack Sub Harmonic Module

So a few weeks ago I got a comment on one of my videos asking if I could do a project with a digital logic chip. So I thought sure, I can do that, but what chip to use? So I dug though my collection of ICs and looked for something that would be musically useful by its self. And I found this chip, the 74HC4040 a 12 stage ripple counter. So in today's video we can going to build a sub harmonic generator. Lets dive right in and look at the schematic.

How does it sound with other than square waves?

What value are the capacitors? Are they 106uf?

[@Recklessexperimentationaudio]

Yes, 10 micro farads, usually written as 106

the schematics are barely readable ... even with a full hd screen. Texas instruments still makes the CD4040 or CD4024 www.ti.com/product/CD4040B VCC (Min) (V) 3 VCC (Max) (V) 18 no voltage regulator needed. a simple 5 volt zener to convert it to 5 volts output.

I did a screenshot and inverted it ibb.co/LtVP2CL (gone in 1 month). I'd opt for CMOS as well so no need for 5V regulator. PS: any idea how to get divisions other than octaves?

[@dcsapporo]

I have built a similar suboctave using the CD4040 that gets its clock in from saw wave generated from a hex Schmidt trigger. Works beautifully. But I haven't tried mixing the individual outs like they are shown here.
