MicroRack - Modular For The Masses? | Starterkits Ep. 14

video upload by Cinematic Laboratory

"I think I can safely say that the world now has a true low budget modular platform. I don't think it can get more affordable than this, without sacrificing the power of a big modular system. The only difference between a full size modular setup and this is... the size. And the beauty of it all, is that it can also exist as a 'regular' eurorack module.

MicroRack is definitely a boutique niche synth ecosystem that sits somewhere between VCV and eurorack. It's a bit too powerful to be a just a toy, and maybe it's too cheap to be taken seriously at first glance. And yet, this is a wonderful starter synth that's just perfect for learning modular for real. It supports many, many synthesis recipes (eastcoast, westcoast), it's analog, it feels like DIY but it doesn't need soldering. It's modular lego that can be mounted in a eurorack case, or travel with you with USB-C power. For more info, check out the https://microrack.org website.

I bought this kit at Dutch Modular Fest 2025 and many of these modules are pre-production prototypes. It's not perfected yet, but even in this state it's a lot of fun to work with. It's already entertaining when it's powered up, just doing nothing else but leds.
I'd love to follow the MicroRack team over the next few years and see how this evolves. It's rumoured that Erica Synths will also contribute a few 'Pico' module ports, so who knows where this all may lead."

Tangible Waves CD40106 Oscillator BRAEDBOARD Build and JAM

1. CD40106 Oscillator BRAEDBOARD Build and JAM 1|🎶🔌🎹 | #synthesizer #electronicmusic #diysynth

I got a BRAEDBOARD (not a typo) breadboard module for an AE modular synth a while ago. I've only just managed to install it. So I thought I'd try some example circuits out from the AE modular Wiki, just to see if it works ok, and also before I go onto something more complex.

00:00 Intro to the BRAEDBOARD.
01:19 Fitting the module into the synthesizer.
03:55 Building the CD40106 oscillator.
04:46 Trying out with the basic oscillator.
05:56 Adding a filter to it. Altering cutoff and resonance.
06:57 Sequencing the filter cutoff.
08:35 The rest of the jam.

Tangram Sequencer TEST V02

video upload by MOS-LAB

"Le prototype du séquenceur avance plutôt bien. Dans cette version, il y a seulement la gestion des Gates sur un channel de 1X8 steps (le projet final comportera 4 X 16 Steps). Les boutons Run/Stop/Reset/Manual advance sont OK. Il y a un menu General Settings pour visualisation Tempo, bascule Clock Interne ou Externe (Clock Midi prévu plus tard) ; et un menu pour les paramètres du channel 1 (Mode de défilement / nombre de pas / Cv range)
La prochaine étape consistera à implémenter les potentiomètres de pas, avec quantisation interne + DAC externe pour 1V/octave, puis sélection ratchet à la volée sur pas désiré."

DIY Oscillator using PIC12F1571

video upload by alloutofsync

"I used this weekend to create a square wave oscillator that operates with the PIC12F1571, which is an extremely affordable CPU available for just $0.71 each.

Since it was my first time using PWM, I spent an entire day generating a square wave at the desired frequency. The required settings and their interconnections were so complex to me, so that I had to carefully investigate each one as I went, which was quite challenging.

The next day, I spent working on ensuring that the output sound smoothly followed the CV input. To convert the CV input into a frequency assuming 1V/Oct, exponential calculations are typically used. However, the PIC12F1571 has limited program memory, so I couldn't use a floating-point math library. I had no choice but to approximate the calculation of powers of two using a Taylor series expansion and rely solely on integer arithmetic. Initially, I approximated up to the second-order term, but the accuracy was insufficient at higher frequencies. Eventually, I extended the approximation to the fourth-order term, which gave excellent results.

While testing with the Pico3 sequencer, I noticed that when the RATE was set to the maximum, the output failed to keep up with the changes. Increasing the PIC's clock frequency from 1MHz to 4MHz resolved the issue, and it followed the changes without any problems.

At this point, about 70% of the program memory has already been used, so I'm not sure how much further I can expand. At the very least, I want to implement duty cycle adjustment. If possible, I’d also like to use an additional PWM channel to detune and combine the signals for richer synthesis."

We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.

NB! All kits in these series are simple and come with extensive user manuals which can be downloaded separately, therefore we will not provide customer support in case your DIY build fails to function or similar."

"JCS BN-1" 4-Bit Linear PCM Synthesizer - Part 2 (Finished)

video upload by blarrer20

"This video demonstrates the final version of a 4-bit Linear PCM synthesizer that I have designed and built over about two months. It makes use of mostly Soviet clones of 7400 and 74LS series TTL chips, with no microcontrollers involved. It has a 256 x 4 SRAM chip that allows the user to program whatever waveforms may be desired, with looping capability, and starting at whatever point desired. Most importantly, it is able to be controlled by an external source, for example a keyboard instrument. It also has a frequency doubler circuit. This video is part 2 of 2, showing the finished product.

Ghost in Translation 16 Inputs 16 Ouputs Teensy Eurorack

video upload by Ghost In Translation

"Using multiplexers for the inputs, the 2 ADCs of Teensy 4.0, shift registers for the outputs, I am able to sample 16 analog inputs at 44.1kHz each, and output 16 sigma-delta digital signals that can be filtered to produce analog signals up to 50Hz.

I am confident I can improve frequency and resolution of the outputs just with software, and will work on that later. For now this is enough for gates, triggers, CVs and LEDs.

This board is my platform for Eurorack modules, Motherboard 2. Everything will be available and documented on GitHub when I finalize a few more things.

Lowrey D350. The MKS50240 is obsolete as far as I know. If anyone can source them put it in the comments. I hope to do a part 2 when finished."
