Synthfox Custom Stuff

Hi there, welcome to my synthesizer corner!

My name's Aubery 'Astro' Lis, and i love synthesizers. I also like making synthesizers, and run the audiogear microbrand SYNTHFOX. I have been making DIY gear since around 2015, and have made big progress since then! Most of all i like creating original new circuits out of cheap common components, as well as enhancing (destroying) parts of other devices' circuitry or widely-known designs. At this website, you can find some nice synthesizer circuits to build!

I value design novelty and creative utility over perfection and universality, so you probably will not find a super-lush-sounding filter or an insanely stable perfect-v/o-tracking oscillator here. What you will find, though, is stuff that turns your audio into squeaky mess, funky logic shenanigans, fartboxes of various complexity and grade 3 veroboard atrocities! Everyone is welcome to build, modify and re-document my stuff, but please, read the disclaimer and copyright info first.

Building a synthesizer system is not too hard or expensive, and is a lot of fun! It's a never-ending odyssey into weird interesting sounds and events. Join me and all other Synth DIY people on this trip, and start soldering already - and i hope my little internet place helps you on your way!


If you want to support SFCS and help me spend more time designing stuff, consider subscribing to "the nerdery" at my patreon!

Aside from designing and building modules for synth systems, i make a lot of other creative stuff as well. Some of my non-modular (or at least non-racked) devices are documented on the 'other gear' page in a non-chronological and non-standardized format. There is a 'music' corner where i have a bunch of my purely-synthesizer-made music: the page contains samplers and download links for actual albums. In the 'stuff' section, you can find a bunch of useful how-to's and info's. I tried making it beginner friendly, even though - as always - i ask y'all to be careful and take care of yourself and your workspace: never solder live synthesizers and stuff! More on that in this tech disclaimer

Also be sure to check out the abouts and my way more personal and less technical neocities webpage here - it's a much less lab themed and a much more personal space.

p.s. also, as you might've noticed, this website isn't really mobile-friendly: it won't ever be, cause i am that nerd who is for actual usable computers' usage, + making it so requires a lot of relatively heavy javascript, and this place should have as much plain stuff phylosophy as possible. Sorry!

Peace Love Unity Respect, and synthesizers!
