Korg Introduces GADGET-VR Music Production Software

KORG Gatdget gets the VR treatment. Note the video appears to start with an Oculus Quest 2 headset. The Quest 2 can actually host apps itself. A PC is optional. So, no idea if the GADGET-VR will run on the Quest 2 itself, PC or mobile. No additional details at this time aside from the video above and the image below. It's worth noting GADGET-VR isn't the first VR music production software. See the VR label for more.

Clock Watcher Erbeverb

Todd Barton

"I just began beta-testing a friend's new, unique clock divider-esque module, Clock Watcher. In this early experiment/exploration the CW is sending random gates directly to the Makenoise Erbeverb (which is in feedback mode) and is also sending gate to various EG which then make their way back to the Erbeverb too. The Erbeverb is the main sound source with some occasional sprinkles of sound from the Instruo Cs-L Complex Oscillator. Enjoy!"

Division 6 Dual Mini Sequencer

Hammond 102200 1974 Synthesizer SN 003098

via this auction

'Hammond 102200 synthesizer manufactured in Japan in 1974/1975 where only 200 units were released for the whole world and of which it is said that only about 30 will remain operational, this makes this synth an authentic rarity within reach of very few people. It has a very authentic sound and is fully operational, it has a very pleasant key to play. The only defects it has is that it is missing a number 7 key in one of the lines of the matrix, discoloration of a small area in the front chrome and typical marks of use. Service manual is included. It is sent anywhere in the world."

NAMM 2021 - Behringer 2600 Blue Marvin and Gray Meanie Limited Edition


This one was spotted and sent in via Soviet Space Child.

"Introducing some of our finest synthesizers ever designed - the Behringer 2600 Blue Marvin and Gray Meanie.

Featuring carefully selected high-grade components for improved performance, a mechanical spring reverb and unicolor fader LED's, the Behringer Blue Marvin and Gray Meanie look back at the rarest first editions of the 2600 that was released in 1971.

We further added some very useful features such as a dual filter, an additional LFO, VCO syncs, USB MIDI, and much more.

Rumoured that only 25 Blue Marvin's and 35 Gray Meanie's were ever made, these modern-day and authentic recreations bring you closer than ever before to these rarities that have always been so out of reach. This time, at a price within reach.

Shipping begins in February 2021 at US$ 699.

Behringer. We hear you."

GSE KVP Pitch Calibration Procedure w/ Korg MS-20 + Keystep Pro


"Audio + Video by G-Storm Electro c. 2021

In this video I will be showing how to calibrate my KVP (Korg Voltage Processor) module.
While I test and calibrate the tuning of all modules, re-calibration may become necessary when the settings get too far out of whack.
I will give some helpful tips as well as a detailed step-by-step explanation of the calibration process.

This video is of a technical nature.
If you're wanting basic information about the KVP and its uses, be sure to check out my other video [posted here]

0:00 Intro, Helpful Tips, Setting Up the Keystep Pro
KEYSTEP PRO: Global Setting CV Base Note = C-2
2:28 V/OCT to Hz/V Calibration
Be sure to trim FREQ with the "low C" note
And trim WIDTH with the "high C" note.
7:01 Hz/V to V/OCT Calibration
Be sure to trim FREQ with the 'A' note
And trim WIDTH with the "high C" note

Keep in mind the KVP is an analog signal converter, controlling an analog MS-20 synthesizer.
And when converting Hz/V to V/OCT, we may be also using the MS-20 to control yet another analog VCO device.
Given these things, the pitch won't be absolutely perfect - but the base frequency and tracking should be well within musically acceptable margins."

Dreadbox Typhon: How to Import & Export Presets With Manager/Librarian Application

Anton Anru

"In this video I'm showing how to import and export presets using Manager app for Dreadbox Typhon.
Check out my soundset for Typhon: Rhythm In Bass. I spent much time thoroughly setting all parameters and modulations, so that each preset gave dynamic and expressive sound.

More details about the soundset:
Dreadbox Typhon - Rhythm In Bass (64 Presets + Sequences):"

Dreadbox Typhon: 64 Bass Presets & Sequences

Anton Anru

"Rhythm In Bass is a collection of 64 Presets and Sequences for Dreadbox Typhon. The soundset covers a wide range of genres and styles: Techno, House, Funk, Electro, Breaks, D'n'b, Pop, Lounge, Downtempo, Psy, and many others.
Each preset has its sequence. You may use it as it is, change it, or send notes from your DAW or any other external sequencer.
But I strongly recommend using the internal sequencer, as I thoroughly set modulations that are synced to the playback. These modulations make the presets and the sequences sound really expressive, dynamic, evolving without touching any parameters.
However, if you tweak Modwheel, Pitchblend (that are set in every preset), and front panel parameters, you will raise a timbre's expression to the new level.

Free Presets for Arturia Microfreak Firmware 3: Vintage Tape (Soundset Demo)

Anton Anru

"And again Arturia make us happy with the release of the new firmware for Microfreak. This time, in version 3, they added three fantastic oscillators by Noise Engineering: Bass, Harm, and Sawx, that give new perspectives in sound design. And what I liked the most is that each of these oscillators has Noise parameter, it sounds very pleasant and give the timbre sort of vintage color.

Also, a unison mode is added, this mean you may stack all 4 voices in one note to get super fat leads, basses, plucks and so on.

Arturia keep on proving that Microfreak is indeed a synth with endless potential. Who knows what else they are going to add to the synth in future, and I can imagine how big this "Micro" is going to be...

When I got the firmware I started exploring the new possibilities immediately, I was excited about the sound and saved some presets in a short time. And now, to celebrate the news I decided to share the presets made with these new oscillators with all Microfreak users.

"Vintage Tape" is a collection of 10 paraphonic ambient presets with some retro mood thanks to the Noise and Detune parameters.

All presets have Press parameter set to Aftertouch, so you may develop the sound with your hands without touching any parameters.

Spiken by BENGE. Modcan A Series (self-playing patch)

zack dagoba

"A minimalist study on the Modcan A Series modular system. This is a self-playing patch which utilises two voltage controlled LFOs to generate the timing pulses, and random voltages to control pitch. There are also two audio samplers in the signal path which help generate the spikes

minipops 2O2 ~ breakbeats 'n' stuff


"a build of jan ostman's O2 minipops arduino drum machine with different samples and patterns

first a quick run through of the patterns/samples:
~ there are 12 patterns selected by push buttons
~ i've added kick, snare, tom, hi-hat and cymbal derived from 808 and casiotone! samples while retaining the original cowbell, clave and maracas

second part shows some MIDI clock sync'ing along with triggered filters via the analog reset out
~ an arduino MIDI sequencer/arpeggiator: drives a Yamaha WT11 with patches
~ the WT11 stereo out runs through separate filters for left and right
~ the minipops reset out tiggers an ADSR (via clock divider and trigger to gate conversion)
~ ADSR output goes to buffered multiples to produce two signals - one to each filter's cv input"

Polyend Tracker & Arturia MicroFreak


'Made by Renoizer"

Modular self-playing patch: Erica Black Sequencer, Roland 510, Octocontroller, Clouds etc.

Brittle stR music

"This is a 3 voice patch, all sequenced from the Erica Black Sequencer:

* Lead sound is the Roland 510 synth voice with auto-panning from the Erica DSP, before going into Halls of Valhalla on the Tiptop Z-DSP.
* The ‘bass clarinet’ sound is the Doepfer A-111-5 synth voice with panning and delay from my DSI Pro-2, then Lexicon reverb.
* The abstract background is a noise source from Abstract Data Octocontroller, band-pass filtered by Tiptop, modulated by a CV track from the sequencer, enveloped and amped, then into Mutable Clouds for some unpredictable granulation. (I have absolutely no idea why it’s doing what it’s doing!)

On the 2 tonal tracks, there’s probability on a lot of the steps for melodic variation. I’ve just acquired the Black Sequencer, and it’s great having probability in Eurorack at last!"

Wing Pinger Pulses

Robin Rimbaud-Scanner

"A rhythmic exploration of the truly inspiring Meng Qi Wing Pinger. A simple live improvisation running the Wing Pinger through the Eventide H9 pedal, and a little bit of looping with the Montreal Assembly Count to 5 pedal later on. A little sketch, nothing more. And, of course, recommended to listen to on speakers or headphones 😀"

Jamuary #19 - Track from scratch on the Spectralis


"Today's Jam is on the Radical Technologies Spectralis, a rare beast, yet one of the most powerful gooveboxes ever made.

I have to admit I dont use the Spectralis that often these days (though that could change after today) ... so really I just wanted to refamiliarise myself it ... as Id forgotten alot.

Then I realised its likely few have seen the Spectralis in action - so decided to do a kind of walkthrough to show it in action.

This is 100% Spectralis, all done on the fly.
the only thing Id prepared was which have some sounds loaded into each part (aka track).... even that I got wrong on last part ;)

So its a warts n' all , so forgive my 'rustiness'.

Coming back to the Spectralis I was struck by a few things:

The sound is fantastic, Id forgotten how good it was.
It has a reputation for complexity, and there is no denying that... but still I was surprised how quickly I got back into it.

As Ive not been using the Spectalis, I have been considering selling it... but have to say a few hours with it has reignitied my passion for it.
There is so much more it can do that I didnt even touch on today.
So, I think I need to put it somewhere where I can use it more again!"
