In questo video mostro come suonare contemporaneamente due sintetizzatori KETRON-SOLTON PROGRAMMER 24 sincronizzati tra loro e poi come far suonare la linea di basso di un PROGRAMMER 24 da un sintetizzatore MINIMOOG DODEL D

Il Solton Programmer 24, lanciato nel 1985, è riconosciuto come uno dei primissimi strumenti a introdurre il concetto di arranger automatico nel mercato delle tastiere, tanto da essere spesso definito 'l'apripista' dell'intero settore.
Questo strumento, prodotto dall'azienda italiana Ketron (con il marchio Solton), è considerato una pietra miliare nell'evoluzione delle tastiere arranger.

Impatto Culturale: è stato soprannominato 'Italian Disco Machine' per il suo ruolo nel plasmare il suono della musica Italo Disco.
Il Programmer 24 non è solo un pezzo di storia per gli appassionati, ma è anche al centro di iniziative come 'Arranger Legacy', un progetto web che mira a preservare la memoria di questi strumenti iconici e dei loro creatori.

Il Solton Programmer 24 è una workstation analogica italiana del 1985, famosa per il suo suono Italo Disco, che combina una sezione ritmica PCM a 8 bit (con uscite separate), bassi analogici, arrangiamenti automatici e sequencer, offrendo un suono vintage caldo e funzionale per produzione musicale. Include funzionalità avanzate per l'arrangiamento, sequencer polifonici e monofonici, MIDI, e interfaccia a nastro, rendendolo un pezzo da collezione apprezzato per il suo 'carattere anni '80'.

Soundplant v.59 Released for Windows & Mac - Soft Sampler Adds MIDI CC, Infinite Undo, & More

Soundplant 59 beat demo: Only2x video upload by Marcel Blum

"Making a beat from a chopped up spy theme with Soundplant, the computer keyboard sample triggering software for Windows & Mac. Version 59 now available for free download at: https://soundplant.org/"



Press release follows:

Caldwell, NJ, USA - Independent developer Marcel Blum has released Soundplant® 59 for Windows and Mac, a major update to the long running sample triggering software for QWERTY keyboards and MIDI devices. Version 59 brings MIDI CC support for customizable control of Soundplant knobs, infinite undo for editing convenience and a/b testing between different effect settings, a master output limiter-compressor for fine tuning dynamics processing, increased sound loading speed with improved multithreading, and other optimizations and fixes.

Soundplant is a standalone software sampler prioritizing low latency and stability for live use, enabling instant playback of any format sound files from standard computer keyboard keys or MIDI. An invaluable tool for sound designers, theater techs, DJs, producers, podcasters, gamers, and streamers, it can mix tons of sounds at once, queue playlists, trigger in the background with global hotkeys while using other apps, record its own output or any input (or both at the same time), and more, all with a powerfully simple drag and drop interface allowing users to create professional soundboards with the ease of dropping sound files onto onscreen keys.

Discussing his Oscar-nominated work on acclaimed biopic A Complete Unknown, sound mixer Terence McCormack Maitland said, "On set when possible, we create a realistic soundscape for the cast. In order to do this we used Soundplant, a deceptively capable app which helped a ton."

Availability & Pricing

Soundplant is available as a free download at https://soundplant.org/ with a 25-launch trial of the paid features. It is free for non-commercial use. A Single User License costs USD $69. Version 59 is a free upgrade for existing license holders who bought in 2023 or later, or a $34.50 upgrade for older license owners. The registered version unlocks professional features including output device selection, expanded sound file format support, output sample rates up to 384 kHz, recording, MIDI, and 'background key input' for global hotkey triggering. Soundplant 59 requires minimum Windows 10 or macOS 10.14.

"The Aion Modular Model 15 provides everything you need for a Moog-style modular system in a Eurorack format. The filter section, the backbone of the Moog modular, includes both the classic low pass filter, passive lowpass and high pass, and a fixed filter bank, providing a myriad of sound sculpting possibilities. Three oscillators are available, two from the voltage controlled oscillator bank and another from the wide ranging voltage controlled oscillator. In addition, two noise sources, white and pink are present for adding texture or a touch of unpredictability. Two classic ADSR envelopes provide modulation and are perfectly paired with the two VCAs or with the filters. Two four channel CP-1 mixers are present at the bottom of the Model 15, which can be used to both mix channels and add pleasant warmth to them. In addition to all this analog goodness, a MIDI to CV/gate converter is included to sequence the Model 15 from external MIDI devices. The Model 15 brings the classic parts of a modular synthesizer into one package that sounds just as rich as the original

Sounds Like the 80s and 90s (In the Best Way) // Waldorf Protein

video upload by Starsky Carr

"Discover the gritty soul of classic wavetable synthesis in this in-depth review and sound demo of the Waldorf Protein. Drawing direct lineage from the legendary PPG and *Waldorf Microwave*, the Protein combines authentic 8-bit, 128-sample wavetables with a modern, streamlined workflow — delivering that unmistakable lo-fi digital bite without the complexity of vintage machines.

In this video, I explore how the Protein’s 8-voice / 4-part multitimbral engine lets a single patch handle basslines, arpeggios, leads and textures simultaneously. You’ll hear how the stepped wavetable movement, classic aliasing artefacts and digital filters create tones that newer, smoother wavetable synths simply can’t replicate.

I also break down:
• How classic PPG-style wavetables actually work
• Why 8-bit waves sound so alive and musical
• Digital filters, drive modes & modulation
• Multitimbral layering for complete tracks
• Why this isn’t a Microwave clone — but something new

Whether you’re into *90s trance, industrial, ambient, IDM, synthwave, techno, or just love characterful digital hardware*, the Waldorf Protein offers a uniquely inspiring take on modern wavetable synthesis."

CONCRETE [ EARLY DEMO ]

video upload by Sasha DZA

"PRE-ORDER OPEN FOR CONCRETE: https://www.lightreft.jp/product-page...
AVAILABLE AT A SPECIAL EARLY PRICE

In this video, we share the first real world tests of Concrete, without aiming for a polished or final demonstration.

We explore how the device works as the final stage in the signal chain, as a master effect, and within a mix on an individual instrument. Throughout the video, moments where bypass is engaged are clearly marked, so it’s easy to hear exactly when Concrete is affecting the signal.

Special attention is given to saturation. We’re exploring how different drive modes interact with dynamics, not as an obvious effect, but as an integral part of the signal path.

We also demonstrate sync mode and stereo operation. The filter reveals a particularly interesting character in stereo, where the interaction between channels adds depth, movement, and a sense of space that is difficult to achieve in mono.

Preorders for Concrete are now open on our website at a reduced price for the first drop. The price will increase for future batches.

https://www.lightreft.jp/"



"Concrete is a next generation compact effects processor that combines digital sound engines with a true analog filter. Each channel features its own analog high pass and low pass filters, designed for precise and musical sound shaping.

Several drive types come preloaded, while additional engines can be downloaded from our website and loaded into free slots, allowing users to build a truly personal sound.
Channels can be used independently or linked together for cohesive stereo processing.

Concrete supports full MIDI control and naturally pairs with Monolit as part of a unified studio and performance ecosystem.

During the preorder phase, Concrete is available at a reduced price for those who want to support the project from the start.
The price will increase at release.

The first Concrete drop is planned for the first half of 2026."

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"Vintage Sequential Circuits Prophet-10 (Double Manual) synthesizer with MIDI in excellent working condition. Legendary dual-manual analog polysynth featuring two independent 5-voice Prophet engines for layered, split, or stacked sounds. Delivers the classic Prophet tone with rich VCOs, resonant filters, snappy envelopes, and hands-on control.

Both keybeds have been professionally restored: bushings replaced and lubricated, contact bars cleaned, J-wires realigned, and keys fully cleaned. Fully tested—both manuals play evenly and respond correctly. On the top left corner there is residue left over from an adhesive Velcro strip that can easily be removed, and the prophet logo on the front panel was touched up by someone. These can be seen in the photos. Some other light cosmetic wear but nothing serious."

Latronic Notron Mk II

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"Latronic Notron MK II (blue) — the iconic, hands-on MIDI step sequencer used by Björk, Peter Gabriel, FSOL, The Orb, and others.

This is the later MK II blue version, produced in very limited numbers (well under 200 units total). Fully working, studio-kept, and tested.

If you know what a Notron is, you already know why it’s special:
real-time, performance-driven sequencing with zero screens, zero menus, and immediate tactile control.

Important / Value Add:
This unit includes TWO spare, pre-flashed processor ICs at no extra cost.

Early Notrons are known to have a rare failure mode where static discharge or power-supply issues can damage the main processor. My unit was shipped back to England to have the main board swapped out in order to prevent this from happening.

Because I took that precaution, I never ran into any CPU problems in nearly 30 years of ownership, but about 10 years ago I acquired several original, pre-flashed replacement CPUs specifically as long-term insurance.

Two are included free with the sale.

I also have three additional spare processors available separately for $75 each if the buyer wants extra peace of mind.

Condition:
– Fully functional
– All LEDs, switches, wheels, and MIDI functions working
– Non-smoking studio environment

One small area of paint has been rubbed off on upper right side where the unit moved against my rack (pictures included)
There are three wide strips of hook-side Velcro on the back. I added these about 15 years ago for live use — it allows the Notron to be held securely at almost any angle (on a stand, case, or surface), which I found extremely practical. (Seriously, this stuff is awesome - I could basically hang the Notron upside down. Highly useful for keeping it on a sketchy stand when in active use.)
The Velcro can be removed cleanly without residue if the buyer prefers, or I’m happy to leave it. (I'd recommend leaving it unless you know you're not going to want it.)

Features at a glance:
– 4-row / 16-step interactive MIDI sequencer
– Per-step velocity grouping, note length, echo, overdrive
– Event-based modulation (pitch, CCs, transposition - this is an incredibly powerful feature and lets you make synths sound completely different than any other device out there)
– Beatwrap & Beatcreep timing tools
– Chord memory, chaining, rebound, Supersteps
– Sends & receives MIDI clock, Start/Stop

Includes power supply. Ships safely packed and insured.

This is one of the most expressive MIDI sequencers ever made — and this example comes with rare, practical long-term protection that almost never accompanies these units."

Roland MKS-100 | The first Roland sampler module (and very few knows about it)

video upload by Espen Kraft

"The Roland MKS-100 from 1986. The Module version of the S-10 with a few minor differences, among them the Midi Mono mode. Sampling time and memory is the same on the S-10, MKS-100 and S-220 (the third and last sampling module in this early series)
Four memory slots (ABCD) with a total sampling time of 4,4 seconds at 30Khz. (8,8 sec @ 15Khz). The S-10, MKS-100 and S-220 all used the Quick Disk (QD) system to load and save sounds.

Check out my Roland S-10, MKS-100,S-220 sample library here: • Roland S-10 Sample Pack | Download now! [video below]

Big thanks to Anders Enger Jensen for lending me the MKS-100 for this video.

Some references say the MKS-100 is from 1987, but Roland made these in 1986 through to the end of the 80s."

Roland S-10 Sample Pack | Download now!
video upload by Espen Kraft

"A brand new sample pack for the Roland S-10, MKS-100 and S-220.
51 different samples taken from my vintage collection of synths and drum machines.
These are QD image files so you have to have a QD floppy emulator installed in your S-10 to use these.
Price is $15USD or €15Euros if you prefer that currency. Send me an email if you're interested. I only sell these through email. You'll find my email in the "about" here on my channel.
All the sounds heard in the demo video are coming from this pack. External reverb is on some of the samples in the video.

I think the Roland 12-bit S-samplers from the 80s has a special sound to them. If you have a S-10/MKS-100/S-220 and you just want some new cool sounds for it then this pack might be for you. These sounds can not be found anywhere else. They're all made by me one way or the other."

Trilling Introduces Passaggio Digitally Generated VCO Eurorack Module

via Trilling where you'll find a demo.

"A digitally generated VCO featuring:

Dynamic 2D waveform control, providing continuous access to all core wave shapes and extended variations. Controllable via front-panel controls and bipolar CV inputs with built-in attenuverters.

Unique alternating cycle-length patterns, creating clean yet harmonically rich distortion by varying individual cycle lengths while keeping the overall period stable.

Standard 1 V/oct pitch input, an adjustable fine-tuning section, and a true hard-sync input for precise, musically stable synchronization.

Optional MIDI input via a dedicated extension module (coming soon)."

Antonus Step Brother DIY - Test Drive w/ A2600, SR-909 and Fractal VP4

video upload by Tumeni Knobs

"It took a couple of months, spending a few hours on weekends, but I got it done! And it's very cool. This demo is pretty rough, but highlights a bunch of the key features of the Step Brother and the "performability" it offers.

See my full build log here: https://www.modwiggler.com/forum/view...

In this setup, the Steda SR-909 is sending midi clock to the Step Brother and the VP4 to keep them in sync. Step Brother is configured to run 2x8 step sequences on channels A and B. Channel A quantized CV output is sent to the 2600 mult and then routed to the CV inputs of oscillators 1 and 2. Channel B quantized CV output is sent to the CV input of oscillator 3.

Step Brother Gate Bus 1 is routed to the 2600 main gate input and triggering the 2600's ADSR envelope. SB Gate Bus 2 is triggering the envelope on the Step Brother and audio out of Osc 3 on the 2600 is routed to one of the VCAs on the Step Brother which is controlled by the Step Brother's envelope. That is then routed back to the 2600's mixer.

Audio out of the 2600 is routed to the VP4, and then routed to the ALA Bartender along with the audio of the SR-909. Output from the Bartender is sent to the iRig Pro and recorded on iPhone with the video.

Cheers!"

First try at making music for FM synthesis

"I'm very happy that Ed Brindley has made this FM sound module for the RC2014 and similar computers. This is the technology used in early PC soundcards and synthesisers like the DX1000. This is my first go at tracking music for this sound card. I used Furnace Tracker, exported to .vgm and ran Ed's music player to play it. You're hearing the capture from the new sound card.

Korg Polysix with Kiwi Technics Kiwisix

Note: links to listings are affiliate links for which the site may be compensated.
video upload by ohm_studi_ohm

"Demo of some patches I programmed on the Korg Polysix. This unit has the KiwiSix CPU board installed that adds many features (like MIDI, sequencing, 512 presets etc) without changing the sound of the synth.
The polysix is a true 6 voice VCO VCF VCA analog synth and it sounds great. By design however the enveloppe is slow and the sound a bit dark due to an added post FX VCF (LM13600). A simple mod allows to bypass this and let the synth shines. With this mod you get a very snappy and funky synth whose SSM2044 filters gets very well along the built-in chorus/phaser/ensemble FX. This unit has this mod done.
From funky keys, to lush string pads, the P6 has a very large scope despite its very limited features.
Only bad point of the P6 is that it has a fairly high noise level. Some improvement can be made like in this unit by adding more ground wires, applying copper foil on the bottom case and adding ferite around wires."

via this Reverb listing, also on eBay

"INSTRUMENT IS FOR SALE AT REDUCED PRICE ON EBAY DURING JANUARY ONLY"

Pics of the inside below.

"Serviced and fully working classic 6 voices analog poly synth.- brand new KiwiTechnics Kiwisix CPU board that adds lot of features (MIDI IN & OUT, CC, sequencer, 512 presets etc)

- all electrolytic capacitors were replaced (the P6 has many of infamous Panasonic CE capacitors that leak after decades of use)

- post FX VCF mod: this simple mod gives the P6 faster enveloppe and fuller sound. A must do on all P6, check demo.- improvement of the ground design by adding more and thicker ground wires, copper tape on the bottom case and ferrite around the data wires

- full calibration

Unit is fully working and sounds great. As expected with these Polysix there still is some light background digital noise due to design, but nothing major, check demo to hear how it sounds.

Cosmetic is good with some scuffs here and there, especially on the case as it often is the case on P6. One switch cap ("hold") is not original."

Roland MKS-80 :: Warm Pads

video upload by Harry van Mierloo

"The Roland MKS-80 isn't known as a typical analog pad machine like the JX-8P or the MKS-70, but still its VCOs are capable of creating some wonderful pads. I couldn't find many pad demos of the MKS-80 online, because most demos contain the powerful analog sounds that the Jupiter-series is so famous for. So I decided to record a few soft pads chords on the MKS-80 for the synth community. As its output is mono, I've added a bit of chorus and reverb from the SQ-5 to spice up the pads.

Played using the Moog Voyager as an expensive MIDI controller using its mod wheel to control the filter, but the fact that you hear polyphonic sounds and see a blinking green MIDI on the blurry MKS-80 in background is the ultimate evidence that you actually hear the MKS-80. ;-)

Enjoy, I hope you'll like it!"
