Spark - A Portable Open-Source Synth (based on ESP-32 and AMY)


video upload by povle

"Meet Spark - a portable open-source synth running the AMY synth engine."

00:00 DX7
01:11 Sampler
02:09 Juno-106
03:23 BLE MIDI

https://github.com/povle/spark-synth


"Really wanted something OP-1 sized but more performance focused (and cheaper), so i made it myself. It runs on AMY, i've currently added the built-in patches and implemented a BLE MIDI keyboard mode, later will start adding my own instruments.

Originally planned to use korg nanokey2 as the keybed, but the feel was so bad that i had to switch to low-profile mechanical key switches.

Overall extremely happy with the result, especially given that it's my first big electronics project"

Modified Univox Mini-Korg For Sale

via Tonetweakers

"Univox Mini-Korg Synthesizer 700 For Sale. This Minikorg has been meticulously refurbished by perfectionists and is in perfect working order and ready to play.

This unit has some very useful modifications that expand its capabilities.

Adjustable Resonance
The stock minikorg just has a single switch for resonance boost, but this one's got 2 additional rotary pots added for variable resonance of the high pass and low pass filters - it really lets this minikorg scream! This mod alone is a huge improvement over a standard minikorg.

Filter Input
There's also an audio input allowing one to process external sounds through its filters.

Adjustable Chorus Rate
There's a pot to adjust the rate of chorus 1.

Octave and Waveform Mixing
These mods give you the ability to mix waveforms and octave divisions, resulting in a fatter sound. These mods are a bit strange and interact with the octave and waveform switches, so they take a little getting used to.

These additional octave and waveform pots are active at the very top of their range and are more like switches and are sometimes inactive, depending on your settings. Sometimes octave switch settings will cause a drop in volume if the appropriate knobs are not adjusted, and sometimes there will be a change in timbre of the selected waveforms if the knobs are not adjusted properly. It's a bit confusing at first. We can probably remove these mods for you if you'd like so the octave and waveform switches work as they normally would in a stock unit, but this will remove the ability to mix waveforms and octave divisions - please email us to discuss if you'd like these mods removed (we would just remove the wires connecting the mods, not the additional pots).

These mods give this minikorg more sonic possibilities than a stock unit and add value to this example.

We paid our tech for 5 hours of skilled labor to get this unit working great again. In addition to fixing any problems, he did the following servicing:

Cleaned jacks
Replaced all power supply electrolytic capacitors (he says someone previously replaced the other electrolytic capacitors)
Replaced fuse
Cleaned and lubed all pots
Calibrated VCO"

ellitone - lil' dream organ - (small batch)


video upload by ellitone instruments

"*small batch - only 7 available -

ellitone.com

The ellitone lil' dream organ is a limited edition battery-powered polyphonic digital synthesizer with built-in amplified speaker.

Featuring 8 wooden Touch Bars, 16 oscillators, 8 selectable musical scales, and a collection of 50 waveforms to explore and blend using the ‘infinite tone’ knob. the lil dream organ is a fun and powerful electronic instrument capable of many tones and textures, simple enough for a youngster or beginner to operate.

Controls:

-‘infinite tone’ knob blends and mixes 2 separate layers of waveforms together. Each layer consists of 8 oscillators and each layer has its own unique selected waveform. As you turn the knob fully clockwise or fully counterclockwise, a new waveform is chosen from a collection of 50 waveforms and applied to one of the 2 layers. This means that you are infinitely blending in-between new combinations of waveforms continuously.

-musical scale select switches. 3 toggle switches at the top of the device are used to select one of the 8 musical note scales. These three switches operate using binary logic. With 3 switches, we have 8 unique combinations of switch positions (on/off/on…off/off/on…etc). Each one of these 8 possibilities selects a different musical scale to explore using the wooden Touch Bar keyboard notes.

GRADIENT NOISE Coming to ICMC 2026

Gradient Noise: Work in Progress with Dirtywave M8 and Processing.org
video upload by John C.S. Keston

https://audiocookbook.org/gradient-noise-at-icmc-2026/

"I'm pleased to announce that I will be performing the world premiere of my piece Gradient Noise at the International Computer Music Conference (ICMC) in Hamburg, Germany on May 11 at 9:30pm. The following video except represent the work in progress. The final piece will be 10 minutes long and contain up to four layers of instruments with independent, corresponding, video objects.

Since 2019 I have been composing animated graphic scores for ensembles and soloists. Examples include Parking Ramp Project, SYNTAX, and Rhodonea. These generative works are projected for both the performers to read and audience to experience. I write software to generate and animate the geometric forms, and establish rules on how the forms are read, whilst allowing improvisation and the emotional response of the performer to play an integral part in each piece.

Gradient Noise, written using the Processing.org language, translates values generated by the Perlin noise algorithm into independent layers of seamless loops repeating at variable intervals. These loops are visualised as geometric forms, abstract visualizations, and evolving structures. The data generated is aleatoric, but the values can be tuned to range between slowly moving gradients or rapid, angular forms. When the sound and visuals are synchronized I respond not only to the animation but also to the changes in the timbre of my instruments.

Through Gradient Noise I am rethinking the relationships between musicians and machines. By translating the properties of n-dimensional Perlin noise into a musical language, the piece presents a unified ecosystem with coordinated timbres and geometric forms. Thus generating a living environment that requires active participation and improvisation. Ultimately, the work presents a contemporary model for computer music where the performer does not simply follow a score, but negotiates a path through a responsive, multi-sensory experience.

Tandberg instrumentation recorder controlling a synthesizer


video upload by A Radiophonic Shed

"This Tandberg Series 115 instrumentation recorder is a scientific logging device from the 1970s.
Voltage changes detected from scientific instruments are recorded as frequency-modulated signals to four separate tracks on ¼" magnetic tape. When the tape is played back for analysis, those same voltages can be examined - replaying the experiment.
Here we have recorded 1V/octave pitch voltages from a keyboard, and now we're replaying those same voltages into a modular synthesizer - all the sound is coming live from the synthesizer, it isn't an audio tape recording.

More details: https://shedsynth.wordpress.com/2026/..."

First Steps with OXI One MKII / EP. 11 Modulation lanes


video upload by OXI Instruments

First Steps with OXI One series

"Learn how to bring your sequences to life with modulation on the OXI One MKII.
In this video, we cover the fundamentals of modulation and how to use modulation lanes to create movement, variation, and expression in your patterns. From assigning MIDI CC destinations to shaping evolving sequences with independent lengths, divisions, and offsets—this is your starting point to unlock a more dynamic workflow.
Using the OXI Coral as an example, you’ll see how powerful modulation can be when combined with proper instrument definitions, and how quickly you can turn a simple loop into something rich and evolving.
We also explore key features like:
– Drawing and editing modulation lanes
– Setting min/max ranges
– Using randomization and smoothing
– Decoupling modulation from the main sequence
– Live recording modulation in real time

This is the first step into a deeper modulation system—future videos will cover LFOs, internal destinations, and advanced routing."

The Sound of Talk Talk - Candy | Vintage Synth Recreation


video upload by RetroSound

"A vintage synth recreation of Talk Talk – Candy from the 1982 album The Party’s Over, performed using original classic hardware synthesizers and electronic drums.

This cover uses the legendary PPG Wave 2.2 synthesizer, Oberheim OB-Xa, Moog Source for bass, and Simmons SDS 8 electronic drums to capture the authentic early 1980s new wave sound of Talk Talk. From shimmering digital textures and warm analog pads to punchy synth bass and iconic electronic percussion, every part was recreated with real vintage instruments.

If you love classic synth pop, new wave, retro electronic music, analog synthesizers, and the unmistakable sound of early Talk Talk, this performance shows the work with the gear from the past.
Check the original track. Written by Mark Hollis."

Arturia Pigments: 50 IDM Arp Presets. Complex & Experimental


video upload by Anton Anru

"☘️ Botanica is a collection of 50 arpeggio presets for Arturia Pigments.
☁️ The bank is inspired by dreamlike, nature-driven atmospheres with digital vibes. The timbres cover a wide spectrum: from warm and cold, noisy and detuned to soft and punchy, dark and bright, clean and distorted, deep and airy.

📦 The download link: https://antonanru.sellfy.store/p/pigm...
👤 The author of the soundset is skendi (Arseniy Pushkov).

🧿 The preset bank places a strong emphasis on complex arpeggio sound design through the use of polymetric functionality in the arp/seq section and modulation rates, as well as a distinctly digital character achieved with wavetables, glitches, pitch shifters, noise, and bitcrusher effects.
As a result, the presets are rich in both content and movement, making them a strong foundation for tracks that require a complex and experimental sound.

🎛️ Each preset features 4 Macros and Modwheel control, making it easy to shape the timbre and adjust key parameters.
The macros are an essential part of the soundset — they can transform the timbre, control noise level and distortion, adjust the gate, and soften the sound. You can control them via a MIDI controller or automate them in your DAW.
🎚️ The Modwheel makes the timbre brighter, while velocity affects both volume and brightness.

🔮 Suitable for IDM, ambient, cinematic, pop, deep, progressive, techno, breaks, jungle, drum and bass, and more.

💡 Compatible with Pigments, Analog Lab, AstroLab.
Make sure you are using the latest software/firmware version.

For AstroLab users.
Import the bank into Analog Lab.
Send the presets to the device.
