Arena Digitalis

video upload by Sid Rockett

"🔊 Learn how to build the Arena Digitalis, a high-performance Arduino granular audio processor for real-time glitch, shimmer, and ambient textures.

In this deep dive, we explore the Arena Digitalis—an open-source Arduino audio project designed for experimental musicians and sound designers.
Granular synthesis is often gatekept by expensive hardware like the Mutable Instruments Clouds or Chase Bliss Mood.

The Arena Digitalis brings those "micro-looping" capabilities to the Arduino Nano/Uno platform using the new R4 processor.

Multigrain Resampling | Recycling and granulizing sounds to create ambient textures

video upload by Intellijel

"In this video, we explore the resampling feature on Multigrain to create ambient textures.

Resampling on Multigrain allows you to internally record the audio from the output of the module - so you can capture your granular sounds, morphing, modulation and audio input as a sample to re-granulize as a new sound.

Matt aims to answer the question: 'what would happen if you resample up to eight times to fill all eight sound buttons?' These patches feature Sealegs, Swells and external sounds through Jellymix and MEMS Mic 3U."

Frippertronics on Stereo-oids // Synthux Spotykach review and demo

video upload by Starsky Carr

"The r3ta of loopers!! Synthux Academy Spotykach is the most unique looper I've ever played. Think two tape machines that can loop, overdub, cross-record from one to the other, slow down, speed up — all with three distinct modes: tape/real mode, a time-based slice mode, and granular mode. Add LFOs, envelopes, a trigger sequencer, an onboard clock, MIDI I/O and you've got a sonic playground that'll swallow hours without you noticing.

In this review and hands-on demo I cover everything: the three playback modes, granular cloud control, tape speed pitch-bending, slice quantisation, stereo routing modes, deck-to-deck recording, LFO shapes (sine, saw, square, sample & hold), the trigger sequencer, loading/saving samples via SD card, and syncing it all to an external clock with the Symmontronic Gnome 2. I'm also running it alongside the Synthux Pro X and a DAW running 808s at 130 BPM — so you can hear exactly how it sits in a full setup.

At $949 it's not cheap, but if you're into ambient, experimental, or textural music, it's hard to think of anything else that does this.

The Spotykach supports:
✔ Three modes — Real (tape), Slice, Granular (Drift)
✔ Dual independent decks (A & B) with cross-deck recording
✔ Onboard clock with tap tempo (internal / external / MIDI)
✔ Trigger sequencer per channel
✔ Two LFOs (sine, sawtooth, square, sample & hold)
✔ Envelopes per channel
✔ Delay & distortion/grit effects
✔ Pitch quantisation (semitones, fifths, octaves, 1–2 octaves)
✔ Three stereo routing modes including stereo randomisation
✔ SD card sample load/save (48kHz 32-bit float, 42 sec max)
✔ MIDI in/out, USB power, headphone out
✔ Voltage per octave (V/oct) input
✔ Pickup mode (no parameter jumps)
✔ Visual LED feedback for every parameter"

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.

Let 3 Modules Do The Talking | Rings, Beads & Marbles

video upload by Dots

"Lost my voice. So this week’s video is a little different — no talking, just patching.

Three modules. That’s it. Mutable Instruments Rings, Beads, and Marbles in a self-contained ambient patch.

Marbles outputs random pitch CV. Rings voices them. Beads processes the output. The result is something slow, spacious, and completely unscripted.

Modules used:
Mutable Instruments Marbles (random sampler)
Mutable Instruments Rings (resonator)
Mutable Instruments Beads (granular processor)"

This was supposed to be an ambient, gentle random sequence combined with quiet beats. But it turned into this within minutes.

First time syncing the PO-33 to anything and it worked perfectly. Quickly created a beat then tweaked the Etherealizer to dial in the granular and delay effects for the Double Knot."

Waldorf Iridium / Quantum - "Harmony of the Spheres" (50 Presets)

video upload by LFOstore

"'Harmony of the Spheres' is a truly remarkable soundset for the Waldorf Iridium and Quantum synthesizers with 50 exclusive presets created by the well-known sound designer, film composer and sound therapist, Otto K. Schwarz. Whether you are composing ambient journeys, cinematic soundtracks, meditative music, experimental electronica or simply seeking moments of cosmic resonance, “Harmony of the Spheres” invites you to become part of this eternal harmony!

As the name suggests, this soundbank is dedicated to the ancient philosophical concept of the harmony of the spheres, also known as Musica universalis. The ancients spoke of the musical and mathematical structure of the cosmos. They believed that the movement of heavenly bodies gives rise to a perfect harmony, expressed through distances equal to the consonant musical proportions — a celestial symphony that resonates through the universe itself.

On the powerful wavetable, granular and sampling engines of the Iridium and Quantum, this philosophy comes vividly to life. Here you will find multi-layered pads that dissolve into infinite cosmic depths, evolving sequences that mirror the the cosmic cycles and events, hypnotic arpeggios that echo the orbital dance of planets and moons, cosmic leads that pierce the veil of unseen, and ethereal keys bathed in the radiant frequencies of starlight.

Otto K. Schwarz, with over 12 years of experience and collaborations with leading manufacturers such as Access Music, Modal Electronics and Native Instruments, brings his signature blend of psychoacoustic depth, emotional intelligence and therapeutic insight to this library. Each preset is meticulously sculpted to evoke not just sound, but a sense of universal connection — a sonic meditation on the hidden music that binds all existence! Experience the Journey!"

An Ambient Exploration in Microsound in Two Parts with Morphagene & Mimeophon

video upload by Genshi Media Group

"::| TO HEAR THE FULL RANGE OF FREQUENCIES AND STEREO EFFECTS, A GOOD PAIR OF HEADPHONES IS HIGHLY RECOMMENDED |::

An Ambient Exploration in Microsound in Two Parts with the ‪@MAKEN0ISEMUSIC‬ Morphagene & Mimeophon. Part one also includes the Make Noise QPAS. Both parts towards the end also include a pair of Radio Music modules (though in Part One the second Radio Music module wouldn't trigger). I will be releasing a 5 Track Album with more of these explorations within a week or two. Further details of this video:

You may be asking 'Why didn't he just use modulation on those parameters?' When I'm using a small setup with just two or three modules, I like to manually "play" the modules like an instrument; using my intuition to guide how I am going to evolve the sound. In my main, bigger system, I of course use all sorts of modulation for some of these things with modules like Batumi, Samara, Zadar and others, but I still always leave room to play the instrument manually.

I've been interested in Granular synthesis and Microsound ever since getting Curtis Roads' book 'Microsound' when it first came out in 2001, but even before that, I had been interested in Musique Concrète, with my first experience of that being when my father (who was a Radio DJ and Concert Promoter) brought home the just released Beatles 'White' album and hearing 'Revolution No. 9' for the first time. I was four years old, and it freaked me out! Part two of this video towards the end gets a little 'haunted' as well, inspired by that revolution of musique concrète!

Pluto's Moons (Album) by The Pedalboard Orchestra

Also see The Pedalboard Orchestra's demos of Modern Sounds Pluto Semimodular Synthesizer

"This album presents ten extended ambient soundscapes (approx. 150 minutes total), composed and recorded using the Modern Sounds Pluto semimodular synthesizer as the sole sound source. Pluto’s architecture—featuring five primary modulation engines named after Pluto’s moons (Charon, Styx, Nix, Kerberos and Hydra)—served as both a structural and conceptual framework during production.
Each track explores different interactions between these modulators, ranging from FM-based timbral shifts to complex CV-driven rhythmic deviations and slow-evolving modulation cycles.

Across the sessions, the wider effects chain underwent several iterations, incorporating various pedals for filtering, spatial processing, and granular-style textural shaping. However, two components remained consistent throughout:

Modern Sounds Pluto (core synthesis + modulation)

Eventide Space (primary reverb stage, used for long-tail ambient diffusion, shimmer variants, and modulated plate algorithms)

All material was captured as real-time, single-track, one-take recordings, with no overdubs or post-layering. Performance control relied heavily on Pluto’s internal modulation matrix, manual parameter riding, and dynamic interaction between the... more

Granular synthesis redefined

Break your samples apart to build new and unique sounds

Play any audio file like a synthesizer-in tune with your song

Explore a new world of sound design with audio as your raw material

A firestorm of granular power

Grainferno is an advanced granular instrument built around a new way of synthesizing sound from existing audio. Its next-gen grain engine breaks your samples into microscopic fragments and rebuilds them into entirely new textures.

From pristine tonal clouds to experimental digital noise, Grainferno turns your sample library into an endless source of playable inspiration.

Make a synth from any sound

Grainferno can generate grains at speeds fast enough to cross into the audio range. At these rates, grains stop behaving like texture and start acting like oscillators-turning any audio file into a playable synth voice.

Even at audio rates, traces of the original sonic character remain, giving you unique synth building blocks with the spectral fingerprint of your source audio.

Add modulation and grain-level shaping to build ready-to-use granular synth tones that stay in tune with your song like a traditional synth.
