Introducing Granulita Versio: Granular chord resynthesizer and shimmer reverb

video upload by Noise Engineering

"Meet Noise Engineering’s chord machine, Granulita Versio.

LIMITED QUANTITIES AVAILABLE: Get your Granulita here: https://noiseengineering.us/products/...

This granular chord resynthesizer takes your audio, slices it into grains, and reconstructs it into chords, clusters, and shifting harmonies. Paired with a shimmering reverb that adds glowing tails and angelic overtones, Granulita can turn even a single oscillator into something lush, cinematic, or beautifully haunted.

Granulita is part of the Versio platform, so once you’ve got your hands on this module, you can swap the firmware with any other Versio effect for free. Unpower the module, plug in the USB, and visit noiseengineering.us to make the swap.

Press release follows:

Noise Engineering announces Granulita Versio, a granular chord resynthesizer and shimmering reverb.

Contact: kris@noiseengineering.us

Los Angeles, CA — Noise Engineering, known for their innovative platform modules, has released Granulita Versio, a granular chord resynthesizer and shimmering reverb.

Granulita Versio offers a simple solution to a complex modular problem. Chords, while beautiful, are difficult and resource-heavy to patch in a Eurorack system. Granulita solves this by generating harmonies for any input signal using a unique granular process. The Chord and Voice parameters allow the user to choose a chord and the note that follows the input signal.

The unquantized Pitch parameter adds an extra layer of harmonic options via transposition, detuning or vibrato.

For fans of granular processing, the Count and Length parameters will be familiar, Granulita can generate any number of grains from zero to 32, and grains can be 16 milliseconds to four seconds long. A modal trigger input and manual button add to the granular fun: freeze grains, sync their playback to an external clock or tap tempo, or use a trigger sequence to manually fire off grain playback.

No granular module would be complete without some atmospheric effects, so Granulita also adds the simple Verb parameter to add in some space. Below noon, small echoes put a patch in a realistic space – but turn up the parameter to add in shimmering octave overtones and feedback into infinity.

Part of the flexible Versio platform, Granulita will be available as an alternate firmware for all Versio owners, completely free, at the Noise Engineering firmware app. However, Granulita breaks the mold with a limited-edition hardware release: only 100 Granulita Versios with exclusive art will be produced, the perfect purchase for collectors or, perhaps, as a holiday gift for the granular enthusiast in your life.

Granulita Versio’s limited run starts December 11th at https://noiseengineering.us and at retailers globally.

Features
● Turn a monophonic signal into a full chord with ease
● Easily create gentle or ominous timbres from any input
● Modulate between 16 resynthesized chord shapes using the CV-controllable Chord and Voice parameters
● Use Count and Length to change the number and size of grains
● Add subtle atmosphere or shimmering, infinite reverb with the Verb parameter
● Create massive soundscapes or use external triggers to fire or freeze grains
● Play grains forwards, backwards, or in random directions

Availability and pricing:
Granulita Versio: Limited run in stock. Shipping from Noise Engineering and retailers starting December 11th, 2025; MSRP US$393

Launchpad Pro MK3 Sequencer.. How did I overlook this?

video upload by Starsky Carr and Novation

"Unlock the true power of the Novation Launchpad Pro MK3 as we dive deep into its sequencer in action — real performance examples, pattern tricks, probability, micro-timing, and creative workflows you can use right now in your studio.

In this video I push the Launchpad Pro MK3 beyond typical clip-launching to show how its onboard sequencer can become the centre of your synth or modular setup. Perfect for electronic musicians, beatmakers and hardware enthusiasts.

Whether you're building evolving patterns, jamming live, or integrating it into a DAWless setup, this walkthrough demonstrates how fast and musical the Launchpad sequencer really is. If you're into hardware sequencing, groovebox workflows, or performance-focused MIDI tools, this one’s for you.

We cover:
• Per-track step lengths for evolving patterns
• Probability per step for generative movement
• Micro-timing & swing for pushing grooves off-grid
• Chord sequencing using Scale Mode & polyphonic steps
• Pattern chaining & Scenes for full arrangements
• Key/Scale locking to avoid wrong notes during performance
• Using the Launchpad as the centre of a DAWless setup"

A path in the dark | Sequential Prophet VS and Rhodes Piano ambient soundscape

video upload by MIDERA

"Two years ago I was playing with my kids with a little yamaha piano, the christmas tree lit, we were looking forward to a relaxing and fun holiday... but that's when my mom called me and asked, "Did you mean what you said? Would you really be willing to come down to be with me?" She was so scared. I dropped everything and drove down (about 1.5 hr drive) to be with her. I'll never forget the look on her face - panic, fear, anguish... I don't know how to describe the look, but it was painful to see. I gave her a big hug as she cried. Looking back, I think she knew it was time, I think she knew her body was failing and was failing fast. I was determined to stay positive, but I watched her move. The exhaustion after only a few steps. I'm glad I didn't realize that it would be only 4 more days before I would lose her forever......."

California's Shortest State Highway! State Route 153 (Gold Country)

video upload by CatSynth TV

"We take a quick ride along 'California's shortest state highway', State Route 153. It runs a half mile in total from a junction with CA 49 in Coloma, California to Marshall Gold Discovery State Historic Park. The park commemorates the discovery of gold by James W. Marshall at Sutter's Mill in 1848, which sparked the California Gold Rush, and features a large monument and statue of Marshall.

Although CA 153 is labeled as the 'shortest', there are a few routes that are de facto shorter, such as CA 77 in Oakland and CA 275 in Sacramento.

The accompanying music features the following instruments:
iOptigan, with 'Bluegrass Banjo' sound set
Cherry Audio Mercury 8
Arturia Piano V and Stage 73 V
EastWest Fab Four and Stormdrum 2
BFD Drums v3"

"(c)2007-25 by RetroSound
supported by UVI: http://bit.ly/retrosound-uvi

Rodina Alisa 1377 - Soviet Analog Synthesizer (1985)
The Alisa 1377 is a rare monophonic analog synthesizer built in the Soviet Union during the mid-1980s.
Manufactured at the Lyubertsy Military Radioplant 'Rodina' near Moscow.
A lead synthesizer intended not for mainstream pop, but for experimental electronic music, sound design, film work and research.
Produced in small numbers, making surviving the units rare.
The Alisa 1377 is fully analog. All waveforms can be used individually or in combination. Frequency modulation (FM) available for all waves.
Pulse width modulation (PWM) with adjustable width and depth.
Octave switches (+1 / +2) and portamento. The sound character is warm, raw and a bit instable. Unconventional compared to western synths. The self-oscillating filter and the FM options allow for metallic, droning, and very experimental tones.

The video sequences are made by Natalja Smirnowa in Dec 2025 in Sankt Pertersburg (Russia)

Additional Tone Tweakers Listings

"This EML-101 was meticulously refurbished and is better than others you may find. This process required 36 hours of highly skilled vintage synth labor, plus parts costs. This unit includes the factory installed pitch bend wheel, which is rare.

Here's a summary of some of the work we did to this instrument that should make it significantly more valuable than others on the market:

We replaced the original handle - those familiar with 101s know the handles often fall apart - we've learned not to carry them by the handle / always carry them with both hands! At the time of writing this description, we see a unit listed as serviced with duct tape holding its handle together. This unit was fully disassembled and cleaned inside and out. Replaced jack washers and nuts. Rebuilt power supply for longevity (replaced electrolytic capacitors and 2 regulators). Replaced metal latches. Replaced electrolytic caps. Cleaned jacks. Removed and cleaned all keys. Removed and replaced rubber keyboard bushings. Cleaned and lubed key contacts and bus bar. Recalibrated CV VCO 1, 2, 3, 4, VCF. Replaced trimpots exp circuit. Replaced all pots that weren't perfect, so this unit works crackle-free and feels like playing a brand new instrument."

"Mint condition vintage 1985 Oberheim Matrix 6 analog polyphonic six voice synthesizer. Boxed complete retail package with original manual, cassette, pedal footswitch, warranty card and promo brochure as pictured. Following the larger Matrix 12 and Xpander models, the Matrix 6 is a full size 61 key 5-octave keyboard design which shares circuitry with the Matrix 6R and Matrix 1000 rack format synthesizers. Original CEM3396 voice chips dated to late 1985. Perfect operation and looks and plays like new. Manual is in Japanese, but English PDF downloads are available in various places online. Power operation is original 100-120V AC, and takes a standard IEC cable. The Matrix 6 can also very easily be converted to 230-240V by simply re-aligning the fuse placement inside, as the internal power transformer is designed for full worldwide operation between 100-240V."
