#synthDIY

2025-07-27

Finished the Moritz Klein voltage-controlled filter module (youtu.be/3tMGNI--ofU) today and hooked it up to the growing #SynthDIY rack (2x VCO, VCA, LFO, and attenuverter). I was extremely surprised to discover that the filter self-resonates!

Everything you hear on the video below, excepting the delay/reverb, was produced from a module that I built myself on through-hole breadboard based on schematics from MKI and others. I’m inordinately proud of this wubby drone! 😁 #Eurorack

Playing my first #livecoding #noise show as ›Shin-Ra Electric Power Company‹ tomorrow (July 24) at...

*Fête du Brûlée*

Also on stage: ^|!<3, Rundfunkorchestra, LADGHA, ah_mult, Nuances d’engrais aka. Physio-Akustik, Shannon Soundquist, JosuaKarlson, in.tension, Fatigue Suspecte, meeek and StöRenFrieD.

There will be little #synthDIY workshop, too, and later on some crêpes for food!

Working on another idea. Sort of a scaling up of my “pico_test_synth”. Code first in CircuitPython then maybe Mozzi Arduino

I previously wired up the remainder of the dronebox (part of the internals seen here) but hit some complexities: 1. The sustain / compression pedal (top) has a very high gain and there is some resonant feedback in this box already, it might be too much and unnecessary, 2. The broken delay (bottom) I hoped only needed new pots remains broken.

Soooo I am doing some light troubleshooting today and figuring out where to go next. If I cannot figure out the delay (which i bought modded), it might be a dud. The sustain I may replace with something else entirely, too.

Bypass switches are not included right now, because of the internal modular design. But I am beginning to see situations I would appreciate having a bypass. So thinking how that can be implemented.

Looking across two separate small circuit boards, both with a lot of yellow colored components and black chips, surrounded by wires.

Quick write-up of a very common mixer circuit. It's used in RDRPT as well:

Arduino AY-3-8910 Direct Digital Synthesis

A lot of devices I make unfortunately never see the light of day. This is a story of one such device.

FilterVerb is a combination of a resonant low-pass filter and a reverb. The low-pass is based on the legendary Korg MS-20 filter, the reverb is built around an Accutronics Belton brick.

What's the easiest way to produce a voltage between -8V and +8V with an #arduino? #eurorack #synthdiy #electronics

Newly rearranged modules for a sequencer + synth voice thing. Nothing new here, just cleared out space in this rack case for another row and built it with modules I own.

And in case you're wondering, yes I did this for the track I'm working on. :)

This is why I love modular fundamentals and synthdiy - need an instrument? Build one! You cannot do that with a lot of the boutique stuff these days... your "sound" is someone else's.

#craque #modularsynth #eurorackmodular #synthdiy

Two full rows of modular synth, unpatched so it is a menagerie of switches and knobs and jacks. The panels on the top row are mostly silver, the panels on the bottom mostly black. On a shelf extending from the bottom are four effects pedals/devices, also unplugged. At the very front is a microphone lying on its velvet red bag.

We're getting there. The encoder still jumps back and forth occasionally, and one of tne of the buttons seems to work only 50% of the time. I assume some faulty soldering, let's see. #electronics #embedded #synthdiy

Aaaaah! Yeeeeha it works!

The two pedals I've completed inside now have their LED outputs routed to the dome lamp. This will change color as I add more pedals.

I made an LED fixture for an antique dome component so that the four LED outputs of the pedals can drive it in unison. It works! Nice turquoise to go with the box, too!!

I have some job finding to do but first peace signs and synth diy.

Standing in front of my turntable and small section of music gear, a large white oval sign hung on the speckled tan wall reads in gold sparkle lettering: s y n t h  d i y - I am wearing a light blue tank top patterned with tacos that have whole sharks inside them.

And this is the serial MIDI version of part 4, but this time I'm back with the original XIAO ESP32-C3.

And part 4 goes back to using the XIAO SAMD21 in the XIAO Synth to create a simple synth module with buttons for voice selection and volume control.
