Two classic 1980's #synthesizer recreations for less than $30? And Eurorack compatible. How...?


video upload by voltryx

"In this video I take a look at the AMY board: a tiny, affordable ($29) Arduino-based DIY synth module built around the open-source AMY synth library. It packs USB, an SD card slot, digital and analog audio, MIDI, and CV I/O into a board small enough to fit straight into a Eurorack case.

I go over what the board actually is and what's in the box, then jump into a MicroPython REPL to show how the AMY library's synth, voice, oscillator model works, patching up a simple sine voice, triggering notes, and using the built-in PCM/sample engine and tag-based sequencer to create a basic drum pattern. From there I install it in my Eurorack rack, run through the signal chain (MIDI in from the Hermod+, CV/audio out, self-modulation via CV), and share some closing thoughts on where it's strong, where it's limited compared to something like the Disting NT, and what I want to try next (serum-style bass patches with compression/distortion).

If you've got one of these boards — or you're thinking about picking one up — let me know what you're building with it in the comments.

AMYboard upgraded: Juno-style sound design with one knob


video upload by voltryx

"My AMYboard needed more hands-on control, so I added a rotary encoder, an OLED screen and a custom MicroPython UI.

In this follow-up, I walk through the hardware, my reinforced 3D-printed Eurorack panel, and two experiments: a three-channel preset explorer using built-in sounds and converted DX7 SysEx patches, and a Juno-style sound-design interface.

Full disclosure: I used Claude and mpremote to develop and upload the code directly to the board.

Want the STL for the panel? Let me know in the comments.

synthemodulaire's first firmware for the Workshop Computer !


video upload by synthemodulaire

"Workshop Fetichist is a firmware for the Workshop Computer by Music Thing Modular. The idea was to turn the Workshop System into an evil analog drum machine inspired by the Body Synths Metal Fetishist.

Download the firmware for free here :https://computer.musicthing.co.uk/pro..."


"Workshop Fetichist is a harsh, semi-random drum machine and noise processor for the Music Thing Modular Workshop Computer (hardware revision 1.1). Inspired by the Body Synths Metal Fetishist, it combines a looping random CV sequencer, probability-based trigger skipping, white noise, external audio processing, and two aggressive effects: Bitcrusher and Distortion. It can also be used as a random CV sequencer and rhythmic trigger source. The sequencer has an internal clock, but can be synchronized via Pulse In 1 or MIDI USB."

The Modular Controller That Keeps Getting Better: Faderpunk


video upload by SynthDad

"What happens when a synth manufacturer opens up its hardware to the community? In the case of AtoVProject’s Faderpunk, something rather exciting!

Faderpunk was already a remarkably flexible MIDI and CV controller, but with the introduction of community-developed apps, it’s becoming an even more powerful tool for modular synthesis, generative sequencing and live performance.

In this video, I explore the new community app ecosystem, show you how to install third-party apps, and dive into some fantastic musical examples.

We’ll explore FP-Grids for generative drum rhythms, TB3PO for acid-inspired sequencing, TechnoKick and TechnoHihat for instant techno grooves, Sift for evolving melodic sequences, and Heat Pump for rhythmic sidechain modulation. I’ll also demonstrate how Automator can record your fader movements and turn them into evolving modulation.

Along the way, we’ll build some musical patches, experiment with sound design, and discover a few unexpected tricks — including using Heat Pump to bring rhythmic movement to the Forge TME Vhikk X.

For me, this is a great example of what happens when developers embrace their communities and give musicians the freedom to experiment and create. And the best part? There’s plenty more to come.

Shoyu Station: A Generative Ambient Fish Synth


video upload by Rarebeasts

"Shoyu Station is a generative ambient instrument I’ve built inside a 3D printed fish.

Twist the snout to pick a creature, press the button to drop it in the tank. Each creature makes its own layer of sound: whale calls, deep ocean drones, bubble melodies, slow tidal swells. Add a few and they build up and drift around each other. A small screen inside the fish shows the creatures swimming about.

It runs on an ESP32 with a small TFT screen, a pot for the snout and a single button.

What creature would you like to see in the tank? Tell me in the comments."

CROWN — DIY Generative Synth made with Teensy


video upload by PhilStudio

"A 16-minute exploration with CROWN, my homemade Teensy-based generative synthesizer, accompanied by visuals from PHOSPHOR.

🔗 Discover the Crown project: https://philstudio.blog/phil-studio-v...

No talking, no tutorial—just sound, evolving patterns, and a few turns of the knobs.

I built Crown out of a dream to create a musical companion for my guitar jams: something that could suggest ideas, explore different styles, and surprise me with just a handful of controls. Its five Crowns shape different aspects of the music, turning a few simple choices into a wide range of possibilities.

An Arduino Nano handles the knobs, displays, and controls, while a Teensy handles the sequencing, musical logic, and generation of notes and drums. The instrument is still a working prototype, evolving with each experiment.

The visuals come from PHOSPHOR, an audio-reactive app I created specifically for this purpose.

Crown Synth

An experimental generative synthesizer that creates melodies, rhythms and textures for spontaneous musical exploration.

Overview

I created Crown out of a dream to build a musical companion for my guitar jams—something I could switch on, explore, and play along with. I wanted to make creating music feel intuitive, with just a few controls to shape the sound and discover different musical styles without getting lost in menus or endless settings. That idea became the five Crowns: five distinct musical personalities, each offering a different starting point for improvisation. Crown brings fresh ideas and unexpected turns to a jam, leaving me free to pick up my guitar and follow wherever the music leads.

The Build

Crown is built around two microcontrollers: an Arduino Nano handles the user interface—knobs, displays, controls, and parameter selection—while a Teensy handles the sequencing, musical logic, and generation of notes and drums. This lets the Teensy focus on making music while the Nano keeps everything hands-on and accessible. A future Sampler Extension, based on the Tsunami Super WAV Trigger, will expand Crown’s sound palette with sampled instruments, atmospheric layers, and other recorded sounds.

The Philosophy and why Crown?

I think of the five Crowns as the guiding forces behind the music. Each one is an abstract control that shapes a whole set of musical decisions, letting me explore different styles and moods with just a few gestures. The name comes from that idea of influence: each Crown rules over part of the musical world, and together they give it its character. My goal was to make something I could play by feel, letting a few meaningful choices open the door to unexpected music.

Bitbox Mk2 Custom Firmware Overview


video upload by Ville Walveranta

"I created a custom patch for the official 2.3.4 firmware that adds a screen saver, speed change without pitch change, vertical waveform zoom, and an easy way to reset parameters to their defaults."

Additional details via the developer:

"I’ve put together a free, unofficial customization of 1010music Bitbox MkII firmware 2.3.4, adding a few features I’ve wanted on my own module. The customized version identifies itself as 2.3.4+c.

What’s added:

Vertical waveform zoom: pinch/spread vertically to adjust waveform height from 25–3200%. This makes quiet samples easier to see and lets you shrink loud waveforms. Horizontal zoom still works normally. A stationary two-finger tap restores 100% vertical zoom and horizontal fit. This only changes the display, not the audio.

Optional screen saver: a black screen after 1, 2, 3, 5, 10, 15, 30, or 60 minutes of inactivity. It’s disabled by default, under Tools → Disp. Playback continues while blanked. The first touch, button press, or encoder movement only wakes the display, preventing accidental edits.

Optional MIDI/CV-trigger wake: choose MIDI, CV triggers, or both. MIDI clock and active sensing are excluded. Unlike physical wake controls, the first incoming musical event still performs its normal action.

Pitch-preserving Speed: 50–200% playback speed, with a dedicated SPEED dial on the Sample-mode LFO/Spd page. It supports live adjustment and the normal INFO modulation editor, including LFO/CV modulation. At 100%, it uses native playback.

Double-tap dial defaults: double-tap a numeric dial to restore its default base value. Modulation sources and amounts remain intact.

Rainbow Looper, a looper for Ableton Move


video upload by KrazyBaldhead

"I created an 8 track looper for Move with the RNBO Move Takeover

Download it here: https://github.com/KBLiveSolutions/ra...

#abletonmove #RNBO #cycling74 #cycling74rnbo #ableton #livelooping #musicproducers #fenderrhodes"


How it works

The 8 loopers

Each looper is controlled by a column of 4 pads (bottom to top):

Red — Rec
Green — Play
White — Stop
Rainbow color — Select (also opens the looper's parameter page)
The first looper sets the base loop length. Every other looper is quantized to it: recording can start freely at any time, but playback always launches on a multiple of the first looper's length, so all 8 loopers stay in sync.

Step sequencing

Each looper has its own step pattern, controlled with Move's step buttons. Turning a step off mutes the looper's output at that point in the loop — the volume envelope for muting is shaped by the Attack and Release parameters.

DIY Eurorack Modules: Tin Man Synths - Music China 2026


video upload by sonicstate

"We spoke to Andrew from Tin Man Synths about his range of DIY Eurorack Modules, a set of simple through-hole designs built around accessible analogue and digital circuits.

The context was China's DIY synth scene, where importing synth brands and beginner kits can be difficult or expensive. Tin Man Synths focuses partly on making local DIY resources more available, alongside carrying other brands.

The range includes a transposing sequencer, which allows one sequence to transpose another, and clocking the two parts out of sync creates a longer rolling pattern of 32 to 64 steps. Other modules include dual attack-release envelopes, a side-chain VCA, matrix mixer, output stages, a semitone voltage-offset processor, the Radius 2164-based filter, voltage-controlled slew, a 40106 VCO, a voltage-controlled LFO, and Daisy Seed-based delay and granular effects.

The modules use through-hole construction, with bare PCBs around $10 and full kits around 400–500 RMB, or roughly $50–60.

Availability is currently mainly China and Southeast Asia."
