Making of: DIY analog 8-step sequencer / synthesizer

This is my second DIY analog synthesizer. I decided to make a video of it's Building process. In the last part of the video, I also show it and my another DIY synth in action. Building analog synths is fun, and after all the initial investments, it isn't even that expensive. If you're interested, I recommend to try it yourself!
The synth uses some basic CMOS microchips (40106, 4040, 4051, 4046 and LM358 op amp) for both, sequencer and the oscillators. It is based on a sequencer circuit from:

If you have any questions about the synth or any other of the DIY devices on the video, feel free to ask on comments below!

Excellent work! 🙋🏻‍♀️😃

watching from Philippines...nice

[@gavindavis7514]

Awesome 👍

[@REBELDONOG]

good job

I need a video of the first si teticer

[@t1d100]

Thanks for the video. Something at the beginning of the circuit must be creating an oscillation that will be manipulated... Is that oscillation coming from the 27uF cap and pot?

[@ryananthony4840]

I have the Behringer WASP, the original WASP had a sequencer u get called the SPIDER and I'd like to build a clone of it...

[@jordinicolaum]

Cool! Are those linear o log pots?

[@olijomusic2481]

I'm not sure if I remember it correctly, but probably mostly linear. Volume pot is probably log.

Did you use a fisheye lens?

[@ckngmad1357]

What's that tall potentiometer name?

[@erozas90]

Can you share your circuit?

Here's a schematic that I sketched on a paper. It may be a little hard to read. Also, there may be some minor mistakes, or some parts that doesn't make any sense. I made some parts of it just by trial and error, so I didn't always really know what I was doing. I never ended up actually making the control voltage outputs, and I don't even know if they would work at all.

What software are you using on your pc to record with the soundcard? I like the spectrum view it has

[@olijomusic2481]

It's a plugin called Edison, in FL Studio
