"Gamechanger Audio Officially Releases the MOTOR Pedal

Electromechanical sound. A gas pedal for your guitar. The ultimate analog noise-machine.

Riga, Latvia – September 29, 2025

After years of development and anticipation, Gamechanger Audio is proud to announce that the MOTOR Pedal is finally available to the public. First teased as a wild experiment back in 2019 and reintroduced earlier this spring as a pre-order, the MOTOR Pedal is now shipping worldwide—bringing a completely new category in sound and performance machines to guitarists, producers, and sonic explorers everywhere.

At its core, the MOTOR Pedal is built on two groundbreaking technical achievements:
A fully controllable musical motor oscillator that transforms brushless DC motors into living, breathing sound sources.
An proprietary monophonic pitch-tracking engine that follows guitars and virtually any instrument with surgical accuracy.
These breakthroughs were forged over years of experimentation. From 2019 to 2022, Gamechanger Audio developed and released the MOTOR Synth MKI and MKII—the world’s first polyphonic synthesizers to use electric motors as vari-speed oscillators. More recently, the company perfected pitch tracking with its acclaimed AUTO Series pedals, released late 2024 The MOTOR Pedal builds directly on these innovations, fusing them into a compact stompbox—creating a powerful, unpredictable, and endlessly fun performance tool.

And in true Gamechanger style, it’s not just about the sound. The MOTOR Pedal introduces a completely new way to control it: a real acceleration foot pedal. This gas-pedal-style controller turns dynamics, pitch bends, and rhythmic sweeps into something you literally drive, delivering an adrenaline-fueled approach to expression that no other stompbox offers.

“Back in 2019, the original MOTOR Pedal was just a spark that set this whole journey in motion - what if we could play MOTORS as Oscillators!?” says Gamechanger Audio founder Ilya Krumins. “Since then, through the MOTOR Synth MKI and MKII and the AUTO Series, we’ve gone deeper and deeper into the world of electromechanical sound. At this point, we feel like we know pretty much everything there is to know about making music with motors and the MOTOR Pedal is the culmination of that knowledge, and the most fun, immediate and accessible way to experience it.”

Key Features:
● Real electromagnetic motor oscillator driven by precision pitch tracking
● Gas-pedal controller with five modes - for dynamic, physical expression
● Hybrid electromechanical + digital signal path for unique textures - five MOTOR engines - each with unique sound
● Compact form factor built for pedalboards, studios, and live rigs
● Replaceable motor block for extended lifetime and serviceability
● Powered by Gamechanger Audio’s MOTOR Synth (MKI & MKII) and AUTO Series technology

The MOTOR Pedal is now shipping worldwide from www.gamechangeraudio.com and with selected dealers world-wide.
The MOTOR Pedal is priced at 399 USD and 399 EUR (incl. VAT) respectively.

WISP - Granular Ambient Modular #17 // Instruo Arbhar, Qu-Bit Mojave, Rhodes

video upload by David Falcon

"noun /wɪsp/
a delicate, thin, and sometimes twisting piece or line of something

Me apetecía algo relajante así que hice una pieza para mí mismo. La idea parte sampleando en el @instruo Arbhar: Rhodes, Piano, Vibráfono, Acordeón, Synth bass y Cuerdas. En mi experiencia, este módulo funciona mejor cuando se samplean frases para luego recorrerlas con su motor en lugar de notas individuales. Lleva a sorpresas y texturas interesantes. En esta jam solo utilicé el vibráfono y el rhodes.

La textura aguda, parecida a una voz, soy yo mismo cantando al micro del @QuBitElectronix Mojave y fijando el búfer. Fui editando el módulo hasta hacerlo funcionar en el tema. La línea de bajo nace en el @MoogSynthesizers Subarmonicon y lo envié al @ShakmatModular Dual Dagger para controlar la dinámica.
En el @WeAreElektron Analog Four añado un Kick, Hi-Hat y dos líneas simples en las frecuencias agudas. También improviso con el Nord con un sonido Rhodes en algunas partes a tiempo real (no he podido montar el vídeo que he hecho en el móvil de esta parte por algun motivo en Davinci Resolve)

Gracias por estar al otro lado!

(eng)
I was in the mood for a relaxing piece so I made one for myself! It started by sampling some new sounds into Arbhar. Rhodes, Piano, Vibraphone, Accordion, Synth bass and Strings. In my experience this module works best when sampling phrases to then sweep around with its engine instead of single notes. It leads to more happy accidents and interesting textures. In this jam only the vibraphone and some rhodes was used.

The high texture vocal-like sound is myself singing into Mojave and locking the buffer. I tweaked the module until I found something that worked. It was mixed with a bass line in the subharmonicon and sent to the Dual Dagger to control the dynamics of the song.
Lastly the Analog Four is adding Kick, Hi-Hat and two simple lines on top. I also improvise with a Nord Rhodes sound on top in some of the parts."

When modules grow limbs: ADDAC's Servo

video upload by Electrum Modular

"Checking out Servo, a unique new module from ADDAC Systems. It can turn knobs or trim pots on a modular, synth, pedal, mixer, or anything else that’s small and cylindrical and that lacks a cv input. Perfect for when your hands are busy doing other things, or for when you want slow LFO-style modulation, or for when you want super precise stepped adjustments.

More info and manual:
https://www.addacsystem.com/en/produc...

Latest Electrum Modular album:
https://smallchanges1.bandcamp.com/al..."

"At ADDAC we always admired the geniality of Neil Young’s Whizzer, way ahead of it’s time, a great example how great ingenuity and engineering can come together to make something great. Inspired by it’s motor controlled method we created a 4HP solution to control any knob that doesn’t have a CV input, while also possible to use for other gear as well (within certain distance constraints).

We use a Servo motor which is a specific type of motor that can be digitally controlled to go to a precise angle. This motor is controlled by a microcontroller that also receives an incoming CV voltage from 0 to +5v and lineary converts this voltage range to the 270 degree Servo motor range.

Using a spring wire and metal couplers the motor shaft is then attached to the target knob to be controlled which will turn as the Servo turns.
Two other knobs [MAXIMUM ANGLE] & [MINIMUM ANGLE] further allow to control the “sweet spot” of the target knob, setting a smaller Servo range.

Raising the [MIN ANGLE] knob above the [MAX ANGLE] knob inverts the Servo range.

We can't stress enough how important it is to read the whole User's Guide thoroughly for this one!

MotorSynth MK2 | By Gamechanger Audio

video upload by Cinematic Laboratory

"When the first Motor Synth was introduced back in 2019, the synth community unanimously agreed to disagree. For some the MOTOR Synth appeared to be a completely ridiculous, overengineered and limited instrument - at one point the phrase “pure embodiment of evil hipster trash” was used, while others called it one of the most innovative and exciting instrument designs the industry had seen in years. The truth lies somewhere in the middle and I feel it's MUCH better and cooler than people think it is.

However, spending 3K on it doesn't make it yours. It's packed with so many features you'll need to find your own gemstones buried in the trash. After spending four days with this unit (on loan, not mine) I realized theirs true magic when it's limitations are starting to work against it. It excels when it fails. Please note, this unit makes a LOT of noise even when it's not connected to any amp or audio interface. Still, the mechanical noise is an essential part of the final experience and you should always record it, even when you decide not to use it later. Most of my recordings in this video has the camera audio, attenuated at -10 dB. It's really loud, but it's not a motor synth without it.

The synth is simply too expensive to make this a review, and I don't do reviews anyway. I try to focus on production value. If you're a pro composer for films and games, this thing is a highly recommended no brainer. The same applies for evil hipsters. If not, try to borrow one from an evil hipster and sample the hell out of it.

Big thanks to Gamechanger Audio for letting me borrow it. This video is sponsored by me, no money changed hands and I can't keep it.

Behringer Model 15: 50 Experimental Patches. No Talking Demo

video upload by Anton Anru

"Welcome to the soundset for the semi-modular synthesizer Behringer Model 15. "Explorer" is a collection of 50 experimental yet usable patches: 12 Leads, 10 Basses, 9 Plucks, 10 Arps, 6 Drones, and 3 Chords.
💾 This soundset offers aggressive, bright, detuned, freaky, noisy, atonal, metallic, generative, evolving, and rhythmic timbres. It stands in contrast to my previous release, "Analog Classics," where I focused on more regular, basic, and classical timbres.
In the "Explorer" bank of presets, I aimed to dive deeper into the modular nature of the Model 15, pushing its boundaries to achieve the most interesting and exciting results.

📦 Get this soundset: https://antonanru.sellfy.store/p/behr...

🎨 Some timbres are designed to take the lead in a track or jam session, while others work perfectly as complementary elements. While the patches are ready to use as they are, I highly recommend tweaking the knobs during your performance to further develop the sound and enhance your creative experience.

🥁 These presets are versatile and suitable for a wide range of genres, including ambient, electronica, IDM, deep techno, house, progressive, trance, lounge, downtempo, pop, chill out, new age, cinematic, breaks, synthwave, retrowave, dub, and more.

📚 The soundset is provided as a PDF document, with each page containing detailed notes that explain how each patch works, which parameters are worth tweaking during playback, and how to evolve the timbre during a performance. By following these notes and making adjustments consciously, you’ll not only get the most out of the patches but also gain a deeper understanding of the synth itself, uncovering its full potential and creative depth.

🎧 Each patch comes with an audio example to help you understand how the timbre is intended to sound, making it easier to integrate into your productions.
To recreate these patches, you will need up to 8 patch cables.

💡 I added pads and drum loops for the video demo to place the presets in a musical context.
These drums and pads are not included in the soundset. I added third-party delay and reverb to the video demo."

Motor Synth MkII and Synthstrom Deluge | downtempo synth performance

video upload by Jay Hosking

"Please support my work on Patreon: / jayhosking
A live synthesizer jam performed entirely on hardware.

Full disclosure: Walrus sent me along the R1 MkII for free. I'm a big fan of their Slöer pedal and also really like the Meraki (both of which I bought with my own money), so I was happy to give the R1 MkII a spin. It's a decent workhorse pedal with full stereo, some cool algorithms (including a sort of granular-delay-reverb thing), and an easy interface. I think the Slöer is still the better pedal if you're choosing based on character/personality, but if you need versatility and a small footprint, the R1 MkII might be for you. I look forward to exploring it more!

Once again, the incredible Miles Away leant me some of his gear to try out. This time, it's the Motor Synth MkII. It's hard to justify at the price point and with a technology that is less known in terms of longevity, and it certainly has some quirks that won't be for some. But man alive, the Motor Synth sounds absolutely incredible: warbly, rich, binaural, capable of mellow lofi ambient all the way up to overdriven bananas cyberpunk. It's incredible.

Check out Miles Away's exploration of the Motor Synth MkII here, and be sure to check out the second jam (heavy industrial electro): • Is This The Most Unique Synth EVER???... [posted here]

Here, I leveraged the mellower side of the Motor Synth and paired it with the Deluge, which is a natural fit in terms of complementary sounds. The R1 MkII was the reverb on the Motor Synth and also was a perfect fit; there's something about the R1's algorithms that makes the good for fitting in a mix. And to glue the Deluge sound together and add a little more personality, I added the Chroma Console doing saturation, doubling, delay, and tape.

Thanks for listening.

The beautifully odd and maddening Motor Synth MkII: 3 things we love... and some things we don't

video upload by MusicRadar Tech

"When the Motor Synth first landed, it’s fair to say everyone was intrigued. Gamechanger Audio even had the likes of Jean-Michel Jarre and Richard Devine enthusing over “the world’s first electro-mechanical desktop synthesizer”. The original instrument made do with two independent voices and four-note polyphony from the eight motors, but plenty of improvements have been made. New to the MkII is the addition of a DCO with four digital oscillators and four-note-polyphony.

In this video, we explore the new features and explore the highlights of this new version – alongside a few things we're not so keen on."

Muro Box-N40 Standard, Continuum, Osmose and Onde

video upload by Christophe Duquesne

"Muro Box-N40 Standard music box track with an Onde from La Voix du Luthier, a Continuum and an Eagan Matrix Module from Haken Audio and an Osmose from Expressive E The N40 is an enhanced version of the N20, the main additional feature being a chromatic scale and internal piezo microphone, both being huge improvements !

The Muro Box-N40 s controlled via MIDI by a Korg SV1.

The voice is built from and analysis of the voice of Khatija Rahman and resynthesised by the Continuum. The pitch and shimmer effect on the Murobox are done by an Eagan Matrix Module. Both are done thanks to the new 10.40 features of the Eagan Matrix.

The murobox is recorded with 3 internal piezo and an IQ7 microphone. The piezo are connected to a small preamp (TubeMP from ART, but multiple others will work). The output of the preamp goes to a Eurorack (in an Eagan Matrix Module). I then a processing chain with a notch filter cuting a frequency band aroud 280/300 Hz, and a noisegate in order to lower the motor noise. The Eagan Matrix module then adds shimmers and pitch effects."

"Muro Box sent a prototype of their upcoming N40 midi music box to test out. This new unit can also do the black keys on a keyboard! (the original N20 version is limited to the C major scale) Here, I'm controlling the plucking of the music box's tines with the OP-1 Field's keyboard by MIDI over USB-C, while sometimes adding in soft sine tone synth sounds coming out of the OP-1 at the same time. Soft sine tones and music boxes have been the Lullatone dream team since the early 2000s : )"

See the Muro Box label below for additional posts.

"Which Music Box Has the Best Sound?

The Beautiful Sound of a Music Box Comes from these key components: Comb, Metal Base, and Wood Box

The N20 and N40 Standard models share the same material and design, differing only in the number of notes and the inclusion of semitones. The N40 Sublime is our flagship model, featuring a four-comb configuration, an acacia wood box, and pure brass base that adds a unique character to its resonance."

"Since its inception, the Muro Box’s external MIDI functionality makes the dream of using a music box as an instrument a reality. Especially with the N40’s 40-note scale, which includes semitones, it meets the arrangement and composition needs of musicians!"

"Gamechanger Audio Launches the Revolutionary AUTO Series Pedals

Gamechanger Audio’s brand-new pedal line, The AUTO Series, is now available online and across all dealer channels, starting with three classic effect pedals – AUTO Reverb, AUTO Chorus, and AUTO Delay.

ABOUT THE AUTO SERIES

Gamechanger Audio is thrilled to announce the launch of its new AUTO Series. This innovative pedal line features the AUTO Delay, the AUTO Reverb, and AUTO Chorus, designed to revolutionize the way musicians experience and interact with classic audio effects. By introducing a new layer of parameter automation that responds and reacts to the player's touch, dynamics, and note choices, The AUTO Series provides an unprecedented level of effects control and creative expression.

At their core, each AUTO Series pedal offers a meticulously crafted palette of sound algorithms, providing a vast range of foundational tones. The primary advantage is the ability to automate these sounds later, but even on their own, they already deliver exceptional quality, making them highly versatile and impressive standalone tools.

Each pedal's AUTO Section has two on-board signal analysis engines, engineered to transfer musical nuances onto the effects parameters. The DYNAMICS tracker is fine-tuned to capture all details of playing dynamics, and animate parameters based on the player's picking style as well as each instrument's loudness and decay. The PITCH tracker detects note choices, and changes in the instrument's tone. These automations can be linked to any of the four effect knobs, setting the parameters in motion.

The entire automation section is engaged with the AUTO footswitch. This allows for the automations to be prepared with the patch cables and then toggled ON or OFF as needed. The small PARAMETER AUTOMATION knobs directly below each of the main EFFECT PARAMETER knobs determine the amount of automation and direction for each parameter individually. The automation functions can be fine-tuned using calibration and several effect engagement modes.

The Design of the AUTO Series pedals draws inspiration from the world of modular synthesis. The series' unique patchbay interface allows to create a straightforward and robust connection between the two on-board trackers and any of the effects parameters using 3.5mm (1 ⁄ 8 inch) jack patch cables.
A batch of six patch cables are included with each pedal.

The AUTO Series PITCH and DYNAMICS trackers are extremely precise and versatile, flawlessly tailored for all styles of guitar playing, yet not limited to string instruments. All pedals feature an input level switch that lets you choose between instrument level (INST), line level (LINE), and Eurorack synthesizer level (EU) input.

While Gamechanger are not hiding their intention of releasing a wide array of popular effects types under the “Automation” banner, the AUTO Series is debuting with three classic time-based digital stereo effects:

SoundMaster ST-305, Roland Jupiter 4 & Echolette SE251

video upload by ohm_studi_ohm

"Quick impro to demo the Sound Master Stix Programma ST-305 (!) analog drum machine syncing the Roland Jupiter 4 arpeggiator. The Echolette SE251 provides echo/reverb.
The ST-305 is an 80s programmable analog drum machine. Very basic, no sound editing but you get 7 sounds, an accent track, dedicated volume faders and outputs for every instrument.
And the icing on the cake is it can be synced to external gear and/or sync other gear, which is a nice feature (you can use it slaved to a sequencer and in the same time slaving a synth, so it acts as a 'through').
I did not know this one till recently and it was a pleasant surprise."

Klemt Echolette SE-251 tape delay.

via this listing

Pics of the inside below.

"This is quite a rare tape echo manufactured by Dynacord. It seems to be one of the very last tape echo introduced by the brand (with the Echolette Echo 400).
It shares many parts with the Echocord line of delays like motor, pinch roller, heads, oscillator board etc
But this one used op amps instead of only transistors for amp stages (the Echocord Super 76 also already used one op amp for the output stage).

The unit has 2 heads which you can mix with the dedicated pot. Otherwise classic features like input volume, tone, echo send level, echo feedback and echo level.
In the back the original DIN socket enabled output and aux input. In this case you only get the wet signal out of the delay, which is nice in a studio environment.

Unit was fully serviced and modded:
- all electrolityc caps were replaced (except 3 bipolar ones )
- original 4x op amps were upgraded to better one (TL081)
- original DIN socket was replaced by 2 jack sockets, one for the output and one for the aux input. Also a pot was added to attenuate the level for the aux input
- unit was meticulously cleaned
- heads were cleaned, demagnetized and aligned
- unit was calibrated
- tape is new

The unit is in perfect working order and in excellent cosmetic condition."
