Xenodrive and DB-01 twins (no talk)

video upload by Richard DeHove

"Why does the Xenodrive not want to let me go? I've had all sorts of good intentions for other content and other devices, stuff that I'm really impatient to show, yet here are we are with the Xenodrive again. I suspect it's down to two things: First that I've cycled through loads of dirt pedals and effects and rarely found one that has more than a single good sound. The Darkglass B3K for example has a brilliant effect on synths, but despite having four knobs and two buttons, it only has one sound. The Xeno has loads of flavors to explore. Second reason I am fixated on this device is that it's finally given me the 'punk synth' sound I've always wanted. Which is largely what we have in this video.

I originally had a big blabfest at the start of this video talking about the Xenodrive in detail but on sudden impulse I cut it all out. I think I was mesmerized by the Xeno and it was giving me instructions. I must exert my free will while I can. If my next video features the Xeno, send help.

Routing here is the MIDI out from the master DB-01 (left) to the rightside DB-01. The master DB-01 has an 8-step random-generated pattern, the leftside DB-01 is empty. Audio goes from each DB-01 to the Xeno left and right. As usual there is absolutely no other processing.

Many thanks to my kind patrons who keep this channel ad-free" My website: https://richarddehove.com/"

Modern Moog Bass - Messenger Filter Modes (no talking)

video upload by Pete Midi

"Moog has defined the synthesizer bass sound for decades. From all Moog mono synths the Messenger provides the widest sound spectrum and in particular, can add interesting variants to the classical bass theme. Here I go through the 4 different filter modes to show the power and flexibility of this synth.

0:00 4P Low Pass
1:35 Band Bass
2:52 High Pass
3:47 2P Low Pass

Recorded with Ableton Live 11 using VISCO and Steampipe 2 (NI Reaktor) plugins for the backing track."

"Probably one of the best examples of the classic Studio 440 anywhere.
Sampler/sequencer/drum machine from Sequential Circuits, circa 1987. S/N 582. The present owner bought this from Wine Country in 2007. It has version 2.30 (SCSI) operating system by Pointsource, 512K RAM, 12-bit sampling, up to 35 seconds sample time (at 16kHz, max rate is 44kHz), 50,000 note sequencer capacity, 8-note polyphonic, stereo audio outputs as well as individual track outputs 1 to 8. And, of course, it has MIDI – very easy to sequence up other synthesizers.

Quite a lot of functionality in a single box and easy to operate. The Studio 440 is fairly rare (about 600 made through 1986, ’87) and considered one of the pioneering forerunners to the later MPC units of the nineties.

This unit is in excellent condition – the cosmetics are very good, with tiny scratches around some of the edges of the enclosure. The main panel paintwork, graphics, knobs and switches are like new. No known issues operationally. Disks load fine, sound configuration, sampling, sequencing and audio all good, menus look normal. Display backlight is good, all hardware good. An easy instrument to get to know and operate, and sounds pretty good for a 12-bit sampler. Includes original manual (NOS from Wine Country), some service data, a number of sample disks, head protector disk (this will have to be ejected following transit) and a survival kit consisting of 8 spare touch pads (unused), two NOS pots, one switch module, one I-624 voice chip. The mains connection is standard IEC socket. The buyer will have to acquire their own mains cord that suits their country and change the internal voltage setting if necessary (explained in the manual. The present setting is 230V).

Weighs 10kg. Unit measures approximately 60x30x16cm (including manual, disks and spare parts). Packaged up, will be maybe 10% larger and heavier. The item is located in New Zealand. Examples of approximate door to door air-freight shipping costs, including insurance, at the time of writing, are: UK/Europe, 300GPB/Euros. USA, $500USD (US tariffs may change at short notice). Australia, $250AUD. Costs to be confirmed upon sale. Importing customs charges and tax are buyers responsibility. You're welcome to find alternative shipping at your expense and risk."

Akai AX80 w/ Custom Wood Side Panels

via this Vemia listing

Click the auction link on top when you get there for additional listings.

Akai AX-80 upgraded with new firmware, new wooden side panels, new pots, new backup battery and most important: fixed panel buttons. The AX-80 is an 8-voice analog polyphonic synthesizer. dual VCO, CEM filters, mesmerizing LED-graph display, programmable as well as preset ROM-programs, and interesting (and deep) modulation options and performance controls. Very lovely to play, and keyboard in very good order. Some of the preset sounds are very 1980s, but there are two banks for you to program your own sounds. New backup battery, completely new firmware from TaunTek added (chips changed), so now filter changes responds without waiting, and MIDI control is updated, several new parts including new volume pot (so no scratching), and new real and very nice wooden side panels. The flimsy voltage switch on the bottom is removed and the synth set to 220 Volts, but all is complete on the inside, so if there is need to change to 110V this is easy on the inside (requires soldering). All synth have one weak point, and for the AX-80 it is the front panel buttons, or more precisely the connections between the three front panel boards on the inside. This has been completely removed, rectified, old connections removed and brand new installed, so all front panel switches work without trouble. As seen from the photos the synth is well used, with scratches here and there, but technically it is now in top shape. All documentation and files are available digitally for the new owner: User manual, service Manuel, preset sounds files, firmware update info etc.

Starsky Carr's Studio: Vintage & Modern Synth Setup Explained

video upload by Starsky Carr

"Welcome to a full synth studio tour — a look inside my hardware setup featuring vintage analog synths, modern wavetable instruments, modular gear and classic drum machines.

See how a mix of vintage synths, modern instruments, modular gear and drum machines all come together in one integrated setup. In this video I walk through the studio, explain how everything is connected, and show some of the instruments that regularly appear on the channel.

The studio is constantly evolving as new synths arrive, others get repaired, and different setups are tested for videos. In this walkthrough you'll see how classic gear like the Juno-60, Prophet series, Minimoog, TR-808, TR-909 and Jupiter synths sit alongside modern instruments such as the UDO Super 8, Groove Synthesis 3rd Wave, Waldorf M, Arturia PolyBrute and Roland System-8.

I also explain how everything is routed through the studio — from CV-controlled vintage synths integrated with MIDI, to the AudioFuse interface and Neve summing mixer that handle the audio side of things.

If you've ever wondered how to organise a hardware synth studio, integrate vintage CV instruments with modern DAWs, or just want to see a room full of iconic synths and drum machines, this video gives you a behind-the-scenes look at the setup behind the channel.

You’ll also hear a few stories along the way — including the slightly ridiculous “six degrees of separation” link from my studio gear to Charlize Theron and Kevin Bacon through the Lock, Stock and Two Smoking Barrels soundtrack.

Whether you're into analog synthesis, wavetable synths, modular gear, or classic drum machines, this studio tour is packed with gear, ideas and inspiration.

Gear featured (selection)

• Roland Juno-60
• Roland Jupiter series
• Moog Minimoog, Voyager % Sub37
• Sequential Prophet synths
• Oberheim OBX8 and OB6
• UDO Super 8
• Groove Synthesis 3rd Wave
• Waldorf M
• Arturia PolyBrute
• Roland System-8
• TR-808 / TR-909 drum machines
• Analog Solutions Leipzig & Fusebox
• Modular & Eurorack gear"

"Elkatwin 61" Vintage Italian string/organ/bass keyboard - only play-

video upload by Davide Micheli

"Elkatwin 61 is a bass-string-organ keyboard built by the Elka Italian synth company in the 80'.
In my opinion is the queen of string machines of that era.
Video consists of two different parts. In the first, I played bass and organ and also some parts with the Crumar Bit99 synthesizer, midi connected to a Solton Programmer 24 synth adopted only as a master keyboard. In the second part, only full strings are played. Video camera recorded the audio by its microphone.
Hope you enjoy the video."

Torso Live Session #5: Ctrls

video upload by torso electronics

"Torso Electronics presents the fifth live session recorded at our office space in Copenhagen.

In this episode, Copenhagen-based artist Ctrls presents a live set built entirely around the S4, using the samples he created for the factory sound library.

Ctrls: “It's composed without any sequencing, only looping and modulation, which is a totally new way of working for me, but which the S4 makes really fun and engaging. The Ableton Push 3 and Intech midi controller act as a my mixer and finalizer, and I'm triggering and effecting some drones and fx sounds from its launch grid. It was a great experience and I'm happy I got to exercise a less clubby side to my music. Big thanks to the Torso team for the opportunity.”

About Ctrls
The Ctrls project was founded In 2012. From the first release the presence of a highly individual sonic style was apparent and his fast paced and futuristic techno based sound has now been well established with a stream of respected music on labels such as Token Records, Earwiggle, Micron Audio, Mechatronica and Key Vinyl. A lifelong devotee of electronic dance music, DJ’ing and live performance are central for the project. This has resulted in many involved sets at globally notable venues such as Tresor, Berghain, Khidi, Fabric, Kit Kat, Fold, Basement NY, and Club Drugstore as well a residency at Copenhagens purest electronic venue: Den Anden Side. The future holds a wider scope as electro, breakbeats, noise and audio visual components are folded into the distinctive Ctrls sound palette."

First Steps with OXI One MKII / EP. 7: Pattern Workflow 01

video upload by OXI Instruments

All parts

"In this episode we explore how to work with sequence pages, pattern length, looping, and editing tools in the OXI sequencer.

First, we look at pages. OXI One MKII organizes sequences into 8 pages of 16 steps, giving you up to 128 steps per pattern. You’ll learn how to navigate between pages, add full pages to a sequence, copy and paste entire pages, and extend your pattern length by adding pages.

Next, we focus on patterns. We cover how to set start and end points, manage longer patterns while keeping full control of your workflow, and use the smart behavior that preserves sequence length when moving loop points. We will also duplicate patterns, and create temporary loops to focus on specific sections of your sequence.

Finally, we explore additional workflow tools, including selecting and editing groups of steps, tie notes across pages, and use the Follow function to keep the view synced with the transport while playing longer patterns. We also look at the Preview function in Mono, Poly, Multitrack, and Chord modes to hear notes, root tones, and chord variations while composing.

DiscoDSP Releases Retromulator Based on The Usual Suspects dsp56300 Engine

via DiscoDSP

[Note: although DiscoDSP gives credit to The Usual Suspects, it's my understanding TUS is not happy about it. From a forum:

"He basically took our source, put his own wrapper on it and is trying to sell it and use it to promote his own business. Can't prevent it, but frankly this is reprehensible IMHO.

Yes. He knows he cannot legally "sell" it due to the licensing model our code is published under. Therefore he sells "support" of "his development efforts" to include difficult things like "git clone" and other Arcane and extremely difficult stuff. sigh... I'd strongly advise anyone using it not to actually pay him for it, but that is just my opinion.]

What isn't clear is whether the UI is just the player above or includes the full editors by The Usual Suspects. I'm hearing it's just the player, which in effect might be an upsell for the full editors by The Usual Suspects.

That said:

"Retromulator brings legendary hardware cores back to life through authentic low-level emulation. The virtual analog synths are powered by a faithful recreation of the Motorola DSP 56300 processor, the Yamaha DX7 runs a full emulation of its original chip set, and the Akai S1000 sampler plays your SF2, SFZ, and Bliss sample banks with studio-quality interpolation. Each core runs its actual firmware or sample data — delivering the unmistakable character of hardware that defined electronic music from the early 80s through the 2000s.

Unlike traditional software emulations that recreate synthesizer behavior by approximation, Retromulator emulates the original integrated circuits at the hardware level. The virtual analog synths run on a cycle-accurate Motorola DSP 56300, the Yamaha DX7 runs a full emulation of its Hitachi HD6303R sub-CPU and Yamaha YM21280/YM21290 EGS/OPS chip set, and the Akai S1000 sampler runs on the SFZero v3.0.0 engine with 8-point sinc interpolation supporting SF2, SFZ, ZBP, and ZBB sample banks. Each core executes its authentic firmware or sample data exactly as intended.

Load the ROM firmware from your own hardware or sample banks from your library, place them in the designated folder, and Retromulator takes care of the rest. The result is not an approximation — it is the real hardware running inside your DAW.

Retromulator is built on Gearmulator, an open-source synthesizer emulation project by the dsp56300 team. We are grateful for their extraordinary work in bringing these classic instruments back to life."

KOSMOS – A Generative MIDI Sequencer for RP2040 (DIY Project)

You might recall KOSMOS from previous posts here. Plantssystem aka GreyScale wrote in to let us know the source code has been released. Details and link to the github repository follow.

"KOSMOS is a compact, self‑contained generative MIDI sequencer built on the Raspberry Pi Pico (RP2040).

Power it on, and it immediately begins producing evolving melodic patterns — no DAW, no clock source, no setup.

The project combines a Euclidean rhythm engine, Japanese‑mode melodic generation (Hirajoshi / Insen / Miyakobushi),
and a 240×240 LCD UI for real‑time visualization of steps, probabilities, and phrase movement.

A small instrument with a surprisingly expressive voice.

Floating Knobs Cuisine: A Performance Sequencer Jam (w/ Critter & Guitari Pocket Piano 201)

video upload by pitch patch

"Cuisine is a performance sequencer built around live interaction rather than step-by-step programming.

This video starts with an empty pattern and builds a sequence from scratch. Gate length, loop range and pattern changes remain flexible, while performance mode allows real-time edits that can be recorded once they feel right.

Cuisine is not about randomness. It is about relationships between steps, timing and control. A simple sequence goes a long way.

Sound source in this video is the Critter & Guitari Pocket Piano 201 via MIDI.
