Homebuild Synth 3 - Voltage Controlled Filter

After building an envelope generator it is time to build something it can control. Therefore this time I build a voltage controlled filter - or VCF - and at the end of the video I do a short demo.

Again the music is played on the Elka X-1000 organ.

Hello, Your vcf has a nice sound ! I built a diode filter, too, I registered the circuitry. Perhaps You can get something like a patent for your filter.

@checkerteck - It was something I found online. I can't remember who made it but it was something that had been used in the 1970's. I have just modified it so it could work with the voltages in this system. So it has probably been patented before.

Now, what will you do with this?

Did you build it just for the fun and hobby of it, or will you actually use it in your music? Just curious.

It all started when I saw a modular synthesizer kit called "Voice of Saturn" from the company "Curious Inventor".

I thought about buying it but after discovering what was inside these quite expensive metal cases I decided that I could build something more musical myself - and to a fraction of what the kit costed. So it is primarily for the fun of it. But since I have finished it I have decided to make at least one piece of music to really show it off!

Is there any chance you could point me to the schematic you used, or something with a similar diode network? This looks interesting. Nice work.

Nice!

It looked so beautiful inside when you were done. I always think your layouts are like works of art.
