Roland JX-70 / JX-10 rack mount note to LED addition

video upload by Craig Barnes

"I had finished this project, but originally the 16 patch and bank buttons were dual LEDs. Today I started to replace them with blanks and thought, what if I leave patch buttons 1-6 as dual LEDs and add a simple processor to intercept the serial Comms between the assigner board and the voice boards. Effectively creating a midi to trigger to display the notes as LEDs."

Introducing Luna: A Lunetta style groovebox & eurorack synth module

video upload by mylarmelodies

Check with dealers on the right on pricing and availability.

"This is your official introduction to the Neutral Labs Luna - a new lunetta-style “groovebox” desktop & eurorack compatible synth. It’s patch programmable, letting you both create tones and rhythms from 5 oscillators (2 with step sequencers inside), logic and pattern generators, all at the same time. Three 'LPG's take the raw tones and let you gate and filter them. 13 effects in 2 blocks effect and shape sounds further.

Enormous thanks to Martin at Neutral Labs for commissioning me to make a vid of this. The world needs more shift registers. Note: I used my own red Tiptop Audio Stackcables in the video, but the desktop module comes with 12 braided patch cables."

What's a Lunetta synthesizer and why should you care? // LUNA from Neutral Labs

video upload by DivKid

"Join us for an exploration of what Lunetta Synthesizers are, what the new Luna from Neutral Labs is and why you should care.

The short answer is that it’s an interesting series of raw digital building blocks from a sonic sculptor (Stanley Lunetta) with lots of modern quality of life features that allow you to approach timbre as rhythm, rhythm as timbre then round that out with low pass gates and FX.

"Logic, Unbound. Meet Luna. The first serious Lunetta synthesizer.

Look beyond clean waveforms and predictable polyphony. Luna will take you back to a time when digital didn’t mean perfect. It meant raw. Inspired by the subterranean DIY culture of the 70s and 80s, Luna is a love letter to the Lunetta machines of old: Living, breathing organisms built from CMOS logic chips. But where those machines were fragile experiments, Luna is a weaponized instrument of sonic confusion.

The Nervous System Exposed. True to the Neutral Labs philosophy, we don’t believe in hiding the magic behind an opaque face plate. Luna features exposed CMOS inputs and outputs right on the front panel. You're not just patching cables, you are rewiring the brain of the synthesizer itself. Combine signals, bend logic, and physically intervene in the computation to create sounds that shouldn't exist.

Rhythm is Timbre. Timbre is Rhythm. In the world of Luna, there is no difference between a sequencer and an oscillator. The same digital pulse that drives a bass line can be accelerated into a screeching lead or folded into a metallic drone.

5 oscillators provide the raw material. A chaotic array of logic blocks (XOR, NOT, AND, shift registers, counters, multiplexer) will chew up those signals and spit out complex, evolving mathematical noise.

Taming the Digital Mess. Raw logic can be harsh. To turn this binary chaos into music, Luna feeds its digital soul through 3 organic low-pass gates. These analog circuits impart a natural decay and percussive punch to the madness, transforming mathematical errors into bongos, plucks, and thumping basslines.

Drench it in Atmosphere. Once you’ve constructed your signal, destroy it again. Luna comes equipped with a suite of effects — distortion, delay, reverb, chorus, bitcrusher, phaser and more — to smear your logic into a wash of ambient bliss or gritty industrial texture.

5 oscillators
logic gates (2 XOR, 2 NOT, 2 AND)
5 logic blocks (5-step ring counter,4-bit binary counter, 2 shift registers, 4-channel multiplexer)
3 touchpads that generate logic signals
3 channels for audio manipulation (low-pass gates with adjustable decay and switchable trigger mode, gain, tilt EQ)
13 audio effects that can be freely assigned to 2 effect slots running in series (drive, delay, reverb, 6 filter types, bitcrusher, phaser, chorus, comb filter)
CV control for effects and 2 oscillators
MIDI control over 2 oscillators, all 3 low-pass gates, and 3 logic outputs (MIDI TRS A socket)
2 sequencers with up to 64 steps, syncable to clock or MIDI
audio output is headphone compatible
available as a desktop synth or 42 HP Eurorack module (desktop version comes with a 12-pack of black/gold braided patch cables)
See more videos and photos on Instagram.

Note: For sustainability reasons, the desktop version does not come with a USB power supply, just a USB-A to USB-C cable. You will need a 5V supply, such as a phone charger, power bank or laptop.

Note: The desktop version has a Eurorack power header and can be placed into a Eurorack. The desktop case however has 5V USB power and no Eurorack rails, you cannot use it as a 42 HP rack without modifications."

"This is a heavily customized E-70 organ with the synth functions of all 3 orchestra sections (upper keyboard, lower keyboard, pedals) fully and independently programmable. Furthermore a 4th solo section has been added.

Although many people have compared converting Yamaha E-series organs into programmable synthesizers to turning them into CS80´s I have always looked much more towards the GX1 connection. The GX1 was the mother of all Yamaha CS´ and contained 1 analog solo synthesizer, 2 polyphonic sections and 1 bass pedal section. So how could the Son Of GX ever be really complete without the addition of such a solo synth?"

Sunset Ambient on a DIY synth

video upload by KellerDev

"Generative sequence on DIY eurorack analog synthesizer. The sequence is quantized to major scale. It has 16 steps, each of which can have up to 8 subdivisions. The sequencer plays them with some random variations. 4 LFOs control filter cutoff, PWM of the oscillator and feedback of the reverb. The delay module that uses the Daisy Seed board is the only digital effect."

From Magazines to MASSIVE MODULAR // Erica Synths Elektor Formant

video upload by Starsky Carr

"The legendary Elektor Formant DIY modular synth from the 1970s is back — and this time it’s beautifully recreated by Erica Synths. In this in-depth demo and review, I explore the history of the original magazine-built Formant, the DIY ethos behind it, and how this modern recreation captures that vintage analogue modular magic.

Originally released as a self-build project through Elektor magazine, the Formant required builders to etch their own PCBs, source components, and assemble modules like the VCO, VCF, envelopes and more. It was true synth-nerd dedication. Now, Erica Synths has made that iconic system accessible again — without the UV PCB lab in your garage.

In this video:

📖 The history of the original 1970s Elektor DIY kit
🔊 Sound demos: VCOs, filter tones, modulation & patching
