"This bi-timbral FM synth is a great addition for anyone looking to take the joy out of synth programming! In all seriousness, this primarily preset machine puts out all of the classic 80's bell and electric piano sounds your heart has desired. Cosmetically this synth is in pretty good nick minus the two missing fader caps as pictured."

"Classic Roland Promars MRS-2 monophonic analog synthesizer in great working condition. This is the rare companion synth to the Jupiter-4, offering a bold, punchy sound with incredible presence and character — thanks to its dual VCO architecture and early Roland voice circuitry.

This unit is in excellent operational shape, with light cosmetic wear on the sides consistent with age. All functions are working properly, and the synth sounds as massive and expressive as you’d expect."

Mike Dean | The Creation of 425 | Moog Music

video upload by Moog Music

"Back in March, ‪@therealmikedean‬ brought us into his world during the making of 425—a 12-track instrumental journey shaped through late nights and relentless experimentation. This video offers a rare glimpse into his creative process: instinctive, unfiltered, and always ahead of the curve.

Stream the '425' album: https://open.spotify.com/album/6Lkygc...

Mike Dean is a legendary producer and synth pioneer known for shaping the sound of modern hip-hop. From Travis Scott’s ‘Astroworld’ to The Weeknd’s ‘Dawn FM,’ his work consistently blurs the line between beatmaker and sonic architect. A master of analog texture and atmosphere, Dean continues to push boundaries with every project he touches... and we continue to look forward to what's next.

This video contains low frequency harmonic content that cannot be reproduced via phone or laptop transducers. Use a pair of headphones or monitors for an optimal listening experience."

Donner Essential L1 Synthesizer (multitracked sound examples)

video upload by Floyd Steinberg

"Here's my take on the #donnermusic #donnerl1 L1 Synthesizer. The L1 is Donner's take on the classic SH 101 synth, but it has some modern extras. Here, I'm showing some dry sounds and also some that were somewhat processed in a DAW. Table of contents:

00:00 hi, what is this?
00:12 what's in the parcel? / hardware overview
01:58 example 1: a punchy bass
02:54 a brassy lead
03:30 a sparkly arpeggiator sound / demo
04:00 all those tracks combined (dry)
04:24 all those tracks combined, but full DAW treatment (reverb, compressors...)
05:19 demo track 2: using the sequencer to create a bass line, drum patterns and so on (full DAW treatment)
08:29 conclusion
08:59 frequency sweep (example)
09:09 sound of warm air decompression ;-)
09:17 flute-like arpeggiator demo
11:36 summary, bye"

Donner L1 Essential // A New Take on The SH101

video upload by Starsky Carr

Additional Donner L1 posts.

"Well this was a surprise... and what a pleasant surprise it is!! The DonnerMusic Essential L1 is an analog synth based around the vintage Roland SH101 with a few modern extras and additional functions, like an extra ADSR envelope, triangle wave, syncable LFO and storage for 128 64 step sequences.

Here I demo it paired with the Donner KB 32M magnetic keyboard which simply clips on and works a treat. So you have the option of a desktop unit or a full synth."

U.D.O SUPER GEMINI the HORROR

video upload by elz production

"One of the most joyful aspects of Gemini is seeing and hearing the dual features work with one another on each keyboard layer, so with the arpeggiator, for example, you can set an independent one for each layer, with different patterns and timings but they sync together so don’t sound out of place."

XTRIKE - my 3rd oscillator is a SH-101

"XTRIKE is Multitimbral. By using the loop machine via MIDI, the looper actually becomes a 3rd oscillator. Here, I'm sampling a Roland SH-101 and layering it on top of XTRIKE's internal synth. Play everything via MIDI and precisely tuning it."

Ambient Improvisation w/ OP-1 field, YAMAHA CS01 After the rain 2025-07-18 by atnr

video upload by atnr

"A piece for ‪@teenageengineering‬ OP-1 field and YAMAHA CS01, where two modest voices gently intertwine into a calm ambient soundscape.

OP-1 field: Records a simple harmonic bed, then overdubs melodic phrases on top. The master effect is MOTHER, adding spacious reverb.

CS01: Played with slow attack and extended release; ‪@strymon‬ NIGHTSKY’s INFINITE is engaged to create a continuous drone while the filter is slowly swept."

Patchwerks Closes Shop

Some unfortunate news in via Patchwerks:

"Patchwerks has closed.

It has been an incredible ride. We created Patchwerks to make a 'third place' away from home and the office that was a safe space for people who wanted to explore making sounds and music with synthesizers.

We started with our meetups in 2016 and grew from there to a little shack off Eastlake Avenue. Then, we outgrew that space and had a shot at a large, beautiful showroom. It was a risk, but we took it. There we had an amazing time building out the store, investing in the community, hosting shows, and more.

We encountered plenty of difficulties in the last few years, and unfortunately now is the time to close the book on our journey.

Having said that, it has been an honor to share our love of synthesizers, music, noise, and community with you all. Keep exploring and keep making sounds. We wish everyone well for what's next."

You can find a ton of content featuring Patchwerks here on MATRIXSYNTH that will live on in the archives. We are going to miss them, and we hope to see them again in the future.

Pacific State/808 State - (Circuit Tracks Version)

video upload by Guinan

"This week’s track is another favourite Hacienda club track. This time from 1989 by the group 808 State (thanks again to Yves Big City @bigcitymastering for inspiring this series).

The original was actually recorded in January 1988 as a reply to the emerging Chicago House scene ‘Pacific State’ has been released in a number of guises. Sometimes just called ‘Pacific,’ others times being labelled numerically after other Roland machines eg. 707, 202. This version is a bit of an amalgamation of a few versions.

Worth noting too that Gerald Simpson ('A Guy Called Gerald') was originally one of the founding members of 808 State before leaving to start his solo career with 'Voodoo Ray'.

I was inspired to cover this after recently acquiring a copy of the Emulator II library disks (to recreate the Kraftwerk track, 'Tour De France' [posted here].
Among these disks, Disk 22 is entitled ‘Loon Garden’. Cited by many as the original source of the ‘Loon’ bird sample we all know and love, it also features a ‘shakahuchi’ sample familiar to anyone who’s ever heard ‘Sledgehammer’ by Peter Gabriel and is a historic piece of sound design. Once you’ve heard these samples you can’t help but hear them across the whole spectrum of popular music. If anyone knows who originally recorded these original samples (also in the Akai S900 library) please leave a comment?

As I started piecing this together I found this excellent video by @CaptainPikant
• Analyzing PACIFIC STATE - How to make clas... [embedded below]
which elegantly detailed the rhythm patterns used. I simplified these somewhat to fit the drum tracks into just 2 tracks to allow room for Sax and Sound Effects tracks (see below).

There is a small snatch of sampled 'sax' played on Logic sampler to fill in for the original sax solo played by Graham Massey from the band but otherwise everything was programmed and played on the Circuit Tracks. No extra synths or FX were used and the audio is recorded straight out of the stereo outs.

I hope you enjoy this track as much as I did putting it together and check back soon for more.

More details for synth nerds.

The bass patch was programmed into Synth 1 to serve as both bass and melody line. The pad sound on Synth 2 is yet another detuned sawtooth pad with chorus, but rolled off with a 24dB low pass filter to create a sound a bit more like the original Juno (said to have been sampled as a chord into a Casio FZ1 sampler).

The drum sounds are a mixture of various 909,707 and 727 Roland drum machine samples from the Reverb Drum Machines collection (normalised and filtered where required).

The Sax sound was played using the sampler instrument in Logic (and is just a preset). The 3 edited phrases were placed onto Drum pad slots and triggered using Drum 3 when required.

Another sample was a ‘bell’ patch created on the Tracks but sampled as a ‘glissando’ to double up the glissando played on the pad on Synth 2, as a break between sections of the song.

Finally Drum 4 was reserved for water and ‘Loon’ sound effects (plus additional 727 rhythm). Did you know the Loon is actually a Canadian diving aquatic bird somewhat like a duck and not at all exotic!

The tracks were as follows;
125BPM, Swing 59%
Synth 1 – bass and melody
Synth 2 – chorused pad chords
Drum 1 – 707 bass drum
Drum 2 – Hihat, Open Hat, Clap and Ride samples.
Drum 3 – Sampled sax lines (and Tracks synth 'bell' glissando sample in break)
Drum 4 – Sound effects, alternating with 727 percussion sampled bongo and muted conga sounds."

Quantum cloud installation or the future of music

video upload by errorinstruments paul tas

"The Future of Music – In the Vision of Paul Tas

Imagine a future where music isn’t something you listen to, but something you create—not with instruments, but with sound itself.

Not songs. Not tracks. But pure, raw, living sound.

This is the vision behind Quantum Cloud, a prototype sound installation and device. It’s not about listening to pre-made music. It’s about building your own sonic world—100% personalized, created in real-time, with machines and light.

Quantum Cloud: A New Kind of Sound Machine

Developed by Error Instruments, this is a highly experimental modular synthesizer—part sculpture, part sound lab. Built around four light-controlled oscillators, it responds to light and to itself. The oscillators can motivate, influence, and synchronize with each other. It includes a unique echo effect, adding depth and motion to your sonic exploration.

This is not just an instrument. It’s a sound experience.
• Patchable and modular
• Fully interactive
• Designed to evolve and inspire
• Meant for the curious, the creators, and the dreamers

Whether placed in your home as a sound sculpture or built at a DIY workshop, the idea is simple: sound becomes yours.

You don’t play music—you create your sound.

Affordable, Experimental, Accessible

We are developing a Do-It-Yourself kit for under €200. You can build it at home, or join a workshop and dive deep into experimental sound-making.

This is just the beginning.
