Playing the Prophet through the most beautiful delay

video upload by Julian "J3PO" Pollack

"I am borrowing the Knif Audio BBD and it's truly the holy grail of bucket brigade delay units. There are only a handful of them in existence, and I'm lucky to get to use it in my studio for a while. The Prophet 10 was an obvious choice to pair with the Knif BBD. I've been getting to know the Knif BBD and decided to record a 10-minute improvisation for you to be able to hear how beautiful these sounds are. Hope you enjoy. Endless inspiration with these two instruments. They are not only beautiful sounding, but beautiful looking and feeling as well."

Gear used in this video:
• Prophet 10
• Knif Audio BBD

Web Based Online Editor for the Original Nord Modular

video upload by Peter van der Noord

"A short update on the browser based Nord Modular Editor that I am currently working on as a fun hobby project."

Additional details via https://nordmodulareditor.com where you can try it out yourself if you own an original Nord Modular:

"Nord Modular G1 Editor

Create, edit and (soon) share your Nord Modular patches with the community.

Some quick remarks:

This is still a very early version. A lot of things don't work or don't work correctly yet.
You should be able to edit patches, browse slots, add modules and cables, adjust parameters and load patches into a slot.
You probably want to run this in the Chrome browser, i haven't tested others.
I have only tested this with a Nord Modular Keys for now, I assume the Rack version will work the same but I don't know about the Micro. I assumed it would work the same but it appears that some people have issues getting it to connect.
Parameter values are often shown as their raw 0–127 values.
None of the displays work yet.
When something is wrong, updates don't come through, or communication seems to be stuck: refresh the page.
When using a trackpad, you probably want to use "scroll to pan" navigation. You can select this in the settings.
To add a module, drag it from the toolbar on top.
To delete a module or cable, select it and hit delete.
The tab key in the editor will toggle rendering cables behind or in front of the modules.
If you were following my personal YouTube channel for updates, please follow my other channel instead.
Feedback is much appreciated, but I don't have a proper way to do that yet.
This is a personal hobby project. I am not affiliated with or connected to Nord in any way.

Using Step 8 with Nibbler and Maths to generate rhythms

video upload by Peter Plugs Patches

"Using patterns from the Schlappi Nibbler to control the current stage of the Joranalogue Step 8, with the Make Noise Math attenuating and offsetting the cv signal to create variations. Sounds are coming from Quad Drum, SSF Entity Ultraperc, Mutable Instruments Plaits, Winter Modular Zaps and Basimilus Iteritas Alter.

"Some exemples of the polyphonic mode (typical 'Oberheim' flavour).

WARNING: i'm not a musician, don't expect a 'killer' playing...

Long resonant filter sweep.
Brass jumpy style
Polysynth saw
Another thing with resonance!

As usual, no traitement except delay/reverb in Cubase."

Patch Memory #5: Micromonsta 2: one synth voice as a complete drum kit

video upload by djr brunstein

"Using one voice of an Audiothingies Micromonsta 2 to build a pseudo drum voice. Sorry for the vaguely rage-baity thumbnail - obviously this synth won't replace any of those drum machines but a man has to find his clicks somewhere!

In the video I say that the synth is in stock- unfortunately it went out of stock whilst I was editing. You can sign up to the waitlist here: https://www.audiothingies.com/"

It's Finally Here // UDO DMNO Review and demo

video upload by Starsky Carr

"The UDO Domino *is here… and it might be one of the most interesting hybrid synths we’ve seen in years. In this full demo, review, and walkthrough, I explore what makes this *8-voice hybrid polysynth so unique — from its dual synth architecture to its incredibly flexible filter section and deep modulation capabilities.

With FPGA oscillators, analog-style waveforms, 32 digital waves, and a powerful dual-engine design inspired by classic SEM-style layouts, the Domino sits somewhere between vintage character and modern sonic experimentation. And yes… it can get beautifully weird.

In this video, you’ll hear real-world sound demos, explore the interface, and see how far you can push this synth — from lush pads to aggressive, experimental textures.

🎛️ What you’ll learn in this video:
Overview of the UDO Domino architecture
Dual synth engines (Domino 1 & 2) and layering possibilities
FPGA oscillators + digital waveforms
Deep modulation options (LFOs, envelopes, cross-modulation)
Advanced filter modes: low pass, band pass, high pass, phase & more
Stereo, parallel & series routing
Effects: chorus, drive, delay, reverb & EQ
Play modes, binaural mode & voice variations
Real sound demos and performance examples

🎧 Why this synth stands out
The Domino goes far beyond a traditional polysynth. With extreme flexibility in routing, modulation, and filtering, it behaves more like an experimental sound design tool than a conventional keyboard — while still being intuitive and hands-on.

🎹 My verdict
This isn’t just another synth — it’s a playable, exploratory instrument that encourages experimentation and rewards creativity. If you like synths that go beyond the obvious… this one’s worth a serious look."

Speak & Music — Lo Fi Retro Synth as a Virtual Instrument (Decent Sampler)

video upload by A Last Picture From Voyager

"I turned a rare 1980s Texas Instruments toy synth - the 'Speak & Music' - into
a full virtual instrument. Here's the demo and a live track built entirely with it.

This little plastic relic from 1981 has one of the most unique lo-fi tones I've
ever heard: wobbly oscillators, crushed bit-depth, and a raw analog character that
no modern synthesizer can replicate. So I sampled every note, every texture, every
glitch — and built a playable virtual instrument from scratch.

ABOUT THE SOUND
─────────────────────────────────
The Speak & Music was part of Texas Instruments' "Speak & Spell" family —
a range of educational toys with surprisingly musical internal hardware.
Its built-in synthesizer produces the kind of retro, degraded, lo-fi tones
that music producers have been chasing with vintage synth VSTs and lo-fi
sample packs for years. This is the real thing, captured and made playable.

Perfect for: lofi beats, ambient pads, cinematic textures, lo-fi music production,
experimental electronic music, and anyone who loves the sound of broken vintage gear.

APHEX TWIN - Pulsewidth COVER (Elektron Digitakt2, Roland SH01a, Prophet REV2)

video upload by nicola neeco

"Recreating Aphex Twin’s “Pulsewidth” using modern hardware synths: the Elektron Digitakt II, Roland SH-01A, and Sequential Prophet Rev2.

This is my cover version of one of the most iconic tracks from Selected Ambient Works 85–92, carefully crafted to capture its hypnotic pulse and raw analog character.

To rebuild the drum section true to the original, I used Roland R-8 drum samples (the same machine Aphex Twin used) loaded into the Digitakt II, and programmed its sequencer for the rhythmic patterns.
And for the iconic melody the same sample Aphex used: the first seconds of the track Butterfly Holocaust by Neutron 9000."

"This collection of vintage synthesizers has grown with me for years. Most all of these instruments have been used on many projects, including VeggieTales, a variety of remixes, and many PlayStation video games and marketing and promotional discs. Most recently they were used on the Mass Effect Andromeda video games soundtrack. They have also been sampled and are part of the SoundVault Collection and the Kurzweil Analog Collection for the K2000 series samplers.
VEMIA note: to forestall many inquiries, The seller’s idea is that he wants to sell it as a whole. That may or may not work out in this auction. If it doesn’t, obviously he’ll be free to do whatever he wants after the auction finishes.

It all works. Everything has been kept in a clean, smoke-free, climate-controlled studio. I have always fixed things myself, so everything is operational and sounding great. I have repair notes on the synths that received attention, though most of them have worked great over the years, without much need for repairs. There are also several MIDI to CV converters so they can all be controlled by computer, plus cables if desired. And a few have cases and manuals.

Polymoog Keyboard, super looks n/w SN 1401

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

"Really nice-looking Polymoog Keyboard (280A, Gary Numan Vox Humana type, serial number 1401) - but not working. The lights come on, but it seems like there's no-one at home.

Very much worth having serviced, because of its excellent cosmetic condition, and because of those iconic sounds and the wonderfully playable keyboard. Photos now done - you can see it hasn't had a lot of use, by the lack of wear on the numbers (even 1: Vox Humana) and because it is still a bit grubby - check the inner bits of the keys which could do with cleaning when it is serviced.

btw it's not every day you see a Polymoog's bottom.... Packing at VEMIA 36GBP."

Yamaha CS50 w/JH Polymodular Interface

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

via this Vemia listing

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

"This is a unique instrument: a classic Yamaha CS50 originally owned by the late Juergen Haible, one of the great synth design explorers of the last 30 years. He died in 2011, less than a year after I drove to Nuremberg to collect this by hand.
Many of his designs and explorations of classic synth and effect architecture found their way into top musicians' possession and have stayed there - I've delivered several to their studios,and they are still there decades later.

The CS50 is great in its own right as one of the warmest, most organic synths ever made, with a wonderful keyboard action and user interface. But this one is unique: Juergen's custom modification turns it into a modular controller as well.

The custom 19-inch rack connects to the CS50 with a set of DIN leads, and acts as a wonderful controller for a modular - or any suitably equipped monosynth. Although the polyphonic features he planned hadn't been completed, it still turns this instrument into something even more powerful and unique. A copy of Juergen's invaluable paperwork is included.

Cosmetically, the CS50 is a bit tatty at the back and is missing the cover for the mains lead on the underside, but is otherwise generally good. The important bits - keys, controls, front panel - are very good.

The rack is excellent, with (we presume) Schaeffer etching. Self powered (230V). Open frame construction behind the front panel, so it must be safely installed in a professional rack.

Two V/Oct outputs with high/low note priority, tune and transpose functions. It also brings out CVs for Aftertouch, PWM oscillator and Sub Oscillator. The 5-pin DIN jacks are *polyphonic* V/Hz outputs - they were intended for a polyphonic modular system, which was never realised. What you use are the 1/4 inch V/Oct outputs.

Checked over by Hideaway Studios in October 2020. I'm ashamed to say that it has sat wrapped up on a shelf ever since, waiting for a studio re-organisation that hasn't happened. So it may need a further check-up. Packing 48GBP - precious and heavy, with two carefully designed packages."
