Korgs Serien bekommen DW8000-Oszilator-Modell Digital-Wellenformen DWGS aus dem DW-8000

DWGS Tim Shoebridge

Der Korg DW-8000 ist brachte zu den Standard-Wellenformen auch einige typische aber statische Basisklänge hinzu, die man um Klavier, Bass und Orgel herum so benötigte – DWGS. Das gibt es schon lange im Microkorg, nicht aber in der *Logue-Serie oder im NTS1. Das ändert jetzt der Tim

Digitale Wellen für neue Korgs

Die digitalen Oszillatoren von Prologue, Minilogue XD und NTS-1 erlauben eigene Modelle und das liefert Tim Showbridge mit dem Modell „Digital Waveform User Oszillator„. Das ist die etwas allgemein klingende Variante, die 16 digitalen Schwingungsformen aus dem Klassiker von 1985, dem  DW-8000, EX-8000 zu ermöglichen.

Diese sind eher eine Welle aus einem Wavetable-Synthesizer aber mit höherer Auflösung als „Samples“. Sie sind also ein einfacher Grundbaustein als statisches Element, was man mit Filtern und Modulation so bearbeiten kann, dass man daraus das gewünschte Zielinstrument nachstellen kann. Das fällt auch leichter mit diesen als mit den Grundwellenformen oder den meist einfacheren 8 oder 12-Bit Waves mit Spiegelung aus diversen Wavetables zu arbeiten.

Nur deshalb klingen sie so „gut“, denn die Wavetables sind in Auflösungen oder Tiefe meist bewusst LoFi gehalten worden und nehmen dann 128 oder vielleicht auch mal 256 Bytes weg und repräsentieren eine volle Schwingung. Das ist sehr sehr kurz und mit einem Sample eher nicht zu vergleichen. Aber es ist eben dennoch sinnvoll. Es gibt kaum Synthesizer die dies oder eine Variante davon einsetzen, deshalb kann man das jetzt mit den neuen Korgs selbst nutzen. Nein, dies sind keine Wavetables, sondern einzelne Waves, also ganz einfach aber wirksam. Und stilprägend für die Zeit der Mitt-Achtziger.


Die Vorgänger wie MS2000, Radias, Microkorg und Microkorg XL in meist längerer Form und mehr davon hatten bereits den kompletten DWGS-Satz an Bord.

DWGS ist übrigens nur das damalige Stichwort für Digitale Wellenformen (GS stehen nur für Generator und System, sind also als Blähworte oder Füllworte da, um das Prinzip zu benennen – bei Roland gab es LA-Synthese – der Einsatz von kurzen Samples, also einen kleinen Schritt mehr als Korg, welche wiederum noch längere Samples in der M1 anboten).

DWGS für alle!

Das alles ist dennoch ein Meilenstein gewesen und hatte mittels der grundlegend „warmen Grundklangstruktur“ des DW-8000 einige Fans, zumal das alles auch leicht und klassisch zu beherrschen war. Deshalb haben auch viele eher klassische Keyboarder damit gearbeitet.

Und das alles kann man jetzt für $19 bei Tim Shoebridge zusammen mit anderen angeboten kaufen und einladen.



A free 8-bit mod delay, and more goodies for KORG ‘logue instruments

KORG’s ‘logue instruments let you run custom downloaded tools – now including recent additions like this excellent free delay.

Roll-log Sounds developed this free 8-bit, 2-tap modulated delay plug-in, which can be modulated for sounds ranging from slapback to drone effects and lots of areas in between.

It runs on the KORG instruments that support the ‘logue SDK – so that’s the Prologue, the Minilogue XD, and even the Nu:Tekt NTS-1. That last one runs just around $100 street, and it’s even smaller than a volca, so it’s a good budget and mobile solution. (It’s similar to the developer board KORG originally released with the ‘logue SDK, with some convenient extras.)

There are some really nice-looking features, including sync, automation, and the ability to do audio-rate modulation of both time and amplitude. You can save presets, too, and to get you started, there are examples for “flanged” mod FX, a delay FX “modulated slapback”, and “dub drone” for the reverb slot.

Features (from the developer’s description):

  • 2.7 seconds 8-bit delay.
  • 2x Delay Taps with independent Time / Feedback control.
  • 2x audio-rate LFOs for stereo time and amplitude modulation of the delay taps.
  • Resonant pre-delay Highpass and post-delay Lowpass Filters.
  • Delay time sync-able to system BPM with custom time division.
  • Delay time, LFO rate and Filter cutoff can be mapped to accurate note for external Midi / CV automation.
  • All 16 internal parameters can be assigned to hardware knobs as macros with user-defined range.
  • 16 preset patches can be packed into one user unit, scrollable through hardware knob.
  • Carefully optimized algorithm, lighter than the factory flanger.

It’s all name-your-own-price, on Gumroad:


This is all a good time to check out the graphical editor logueMill, from the same developer. For now, it only has an editor for this Del-8 delay, but it’s possible we’ll see more tools supported in future. Also pay-what-you-will, so throw some coffee money at Roll-log Sounds!


Okay, I know that this shouldn’t appeal to me, but it does. Never tell me not to do something:

Important notice for Nu:Tekt NTS-1: currently there’s a bug that allows you to use custom delay and reverb concurrently, this is NOT INTENTED and may cause the two custom fx to malfunction or worse; if you aren’t sure you wouldn’t accidentally enable both of them, it’s highly recommended to not install any custom reverb until a firmware patch fixes it. Prologue and Minilogue XD does not have this issue.

But wait, there’s more in ‘logue news:

Distortion and bitcrushing/decimate from Sinevibes

Our friend Sinevibes, aka Artemiy, continues his run of great stuff for the KORG platforms.

This time, you get a 5-algorithm multi-effect distortion (Corrosion), and a sample rate + bit depth reduction (DCM8 – “decimate,” get it?):

Corrosion features a total of 5 different distortion curves that enrich the input signal with new harmonics, each doing it in its own unique way. This algorithm is built with 2x oversampling to reduce aliasing, giving a cleaner high-frequency response, and also includes an input noise gate to eliminate static analog noise amplification.

DCM8 changes the input signal’s digital resolution in both time and amplitude domains, degrading its quality. This results in the typical digital distortion – frequency aliasing and quantization noise, reminiscent of vintage sampling machines. Just like Corrosion, DCM8 also includes an input noise gate.

Sound mangling oscillators

Developer Tim Shoebridge is also making custom user oscillators, all for $12. (Swap that overpriced panini for an instant ramen and go!)

FOLD, the newest addition from Tim, emulates analog wave folding circuitry. There’s a long demo video, with some beautiful, warm space-out … s…. oh dear… must … finish … article … must not just … watch ambient music and wavefolding explanations…

He’s got a ton of other nice stuff in there, like simulating analog string synths (nicely lo-fi stuff there), plus a unique approach to plucked string modeling. Tim has done a nice job of making something vaguely like things you’ve heard before, but with a particular, grungy-retro tilt that’s all his own.

Check them all:


All of this means, on even a fairly tight budget, you’ve got excellent choices both in the KORG stuff and in the Arturia MicroFreak with its custom oscillators. Either way, you get a range of wavetable and custom oscillators and effects. Heck, at these prices, you could pick up both. The workflow is totally different, but you would have at your disposal a lot of the same sonic range as a fairly pricey modular rig – and in form factors that might be more convenient for keyboardists, too.

I’m personally keen to try pairing our MeeBlip geode with a KORG NTS-1 (on effects, or adding voices) for an ultra-compact rig.

But this isn’t only about KORG, nice as the KORG stuff is. What we’re seeing is finally the commoditization of digital architectures are starting to make our hardware look as flexible as our software. I think that’s a very good thing, in that it takes a wide sonic palette and makes it eminently accessible and tweakable.

So happy new year, indeed. And here you can spend a few bucks on downloads and feel like you’ve got a new rig and get straight to playing it, even before we get to all the NAMM gear announcements next week.

Previously, Artemiy spoke about his developer experience and why he likes this approach:

Korg Prologue bekommt das 2.0-Update

korg prologue synthesizerkorg prologue synthesizer

Die kleinen Synthesizer vor dem Minilogue XD haben das 2.0-Update bereits schon länger bekommen. Dabei haben sie einige Funktionen hinzu bekommen, die der Minilogue XD zuerst anbieten konnte.

Der Prologue hat nun die alternativen Tonskalen in Form von Microtuning hinzu bekommen. Außerdem wird nun stets auch der bisher eingestellte Wert angezeigt, wenn man an einem Parameter dreht. Dazu ist man nun in der Lage Delay und Reverb per Dry/Mix zu steuern (Mix Control). Es handelt sich also nicht um „Nebensächlichkeiten“ bei dem Update, sondern sie machen viele besser. Dazu gehört auch der Empfang von Aftertouch via MIDI und die Zuweisung auf was dieser wirken soll, dem Arpeggiator zu sagen, wie schnell er laufen soll und welche Gate-Zeiten er hat. Weniger entscheidend ist die Möglichkeit das Oszilloskop abzuschalten. Aber es geht jetzt.

Ansonsten enthalt das Update auch Fehlerbereinigungen. Beispielsweise das Delay – Clocking bei externem Betrieb, die Einstellungen für Oszillator-Parameter mit bipolaren Einstellungen (positive und negative) und eine Entwickler-Änderung betreffend sowie diverse andere kleine Dinge wurden verbessert beziehungsweise „repariert“. Ein sinnvolles und kostenloses Update, was jeder Nutzer sofort einspielen sollte. Nachteile gibt es keine. Die Möglichkeiten für den digitalen Oszillator findest du hier.

KORG NTS-1 is here: A pocket ‘logue voice as $99 DIY kit

KORG is kicking off a new product line – the DIY-focused Nu:Tekt – with a $99 screw-together instrument. And it has the same programmable guts as you find in the prologue and minilogue xd, complete with SDK.

The Nu:Tekt NTS-1 is funny to describe, in that it represents different things to different people. For the very few of you who are actually audio programmers, it’s something special … but it might also be of interest if you just want an inexpensive sound toy or particularly like operating a screwdriver. Let’s break it down.

If you just really love using screwdrivers: Yes, this is a kit. There’s no soldering involved, if you need the smell of hot solder flux more than the calming grip of a Philips head.

But if you do enjoy a bit of assembly, you do get the NTS-1 in pieces you screw together. If you love screwdrivers but also have … misplaced all of them (I feel you), there’s even one in the box.

If you want an amazing pocket instrument for $99: Holy crap. The NTS-1 is very possibly the most synthesizer per dollar I’ve seen. KORG actually don’t even really describe how powerful this is in the press release, sheepishly saying it’s “inspired by the MULTI engine” on the prologue and minilogue xd.

So, you have something that’s small and has some onboard jamming features, like a KORG volca, but with the audio depth of their flagship instruments. And it’s even cheaper than a volca – even if you’re the one doing some of the final assembly, and the case and fit and finish are a bit more ‘rustic.’

It actually is the guts of the ‘logue voice. See the developer section below; the NTS-1 retains compatibility with the prologue and minilogue xd.

So that means you get the single oscillator from the ‘logues, plus a multimode filter, a single envelope generator, three (!) LFOs, and three (!) effects processors – reverb, delay, modulation.

You can play that, volca style, using an onboard arpeggiator. Or you can connect MIDI input. Or there’s an audio input, too, making this a very handy pocket-sized effects units for other gear.

For those of us who love collecting little sound boxes, like the Pocket Operators, volcas, Twisted Electrons, and our own MeeBlip, I can see the NTS-1 doing double-duty as an effects box and extra sound source. Life is getting pretty darned good for us – you can literally put together a full studio of gear for the price of one high-end Eurorack module, you know.

That’s already worth a hundred bucks, but the really interesting bit is that the NTS-1 is supported by the ‘logue SDK. This means you’ll be able to load custom effects and oscillators onto it, almost app style.

There are 16 custom user slots for loading your own oscillators, plus 16 slots for custom modulation effects, 8 reverb effects slots, and 8 delay effects slots.

That’ll be fun even if you aren’t a developer. As a non-coder, you probably don’t want to mess around with GitHub and the SDK, but KORG is planning a librarian and custom content page you’ll be able to use on the Web. which will eventually be here:


And if you are a developer, well –

If you’re a developer: This just solved two problems for you in getting into KORG’s SDK for the ‘logues. First, it makes your price of entry way cheaper. (And even developers I know who own the keyboards are considering buying this, too, because it looks like fun.)

Second, if the NTS-1 takes off, the installed base of people who can make use of your creations also expanded.

The SDK here supports both custom oscillators and custom effects, as with the full-fledged keyboards. Check out the dedicated SDK page:


Full details:

  • Ribbon keyboard
  • 1 digital oscillator, 1 multimode filter, 1 EG, 3 LFOs
  • Multiple effects: Mod (chorus, ensemble, phaser, flanger), delay, reverb
  • Minijack audio in and out
  • Minijack MIDI in jack
  • USB port (definitely necessary for loading custom programs, but I think also supports USB MIDI – I’ll check)
  • Runs on USB bus power (< 500 mA)
  • 129 mm x 78 mm x 39 mm / 5.08” x 3.07” x 1.54”
  • 124 g / 4.37 oz
  • USB cable, manual, and screwdriver in the box

The NTS-1 ships in November. I’ll definitely try to get one. US$99.

Korg – Staub-Oszillator für die Minilogue XD / Prologue – Serie und vielleicht den neuen kleinen…

Staub KorgStaub Korg

Korg zeigte auf der Superbooth stolz den Desktop des Minilogue XD und auch ein neues kleines Teil, welches die gleiche Technikbasis verwendet wie jener digitale Oszillator im Prologue und Minilogue XD. Dafür gibt es jetzt ein weiteres Angebot namens Staub-OSC.

Staubsauger-Oszillator ist offenbar der volle Name, damit ist der Hoover-Sound gemeint, den es ursprünglich auf dem Alpha Juno gab, später im JP8000 und eben dann auch allem, was Super/Hyper-Saw heißt und quasi mehrere Oszillatoren darstellt, die gegeneinander verstimmt sind. So etwas findet man auch im System 8 von Roland und vielen weiteren. Hier sind es vier Oszillatoren, die mit modulierten Sägezähnen arbeiten, die oberhalb und unterhalb für orchestrale Breite sorgen. Diese Basistechnik kann man für grundsätzlich breite Klänge, Flächen aber auch Bässe verwenden.

Es ist zudem wichtig zu verstehen, dass man nicht nur 90er-Trance mit dieser Basis erstellen kann, es ist schlicht und einfach ein mehrfacher Oszillator oder wahlweise kann man es auch als Suboszillator-Sammlung begreifen mit Gegenstimmbarkeit. Das kleine Demo führt ansatzweise vor, was damit möglich ist und kann „orchestral“ bis breit klingen.

Weitere Information

Die Website zum Staub-Oszillator erklärt alles und möchte mit $4,99 belohnt werden. Da Korg keinen Shop oder Sammelsystem hat, findet man die ganzen Angebote jeweils beim Entwickler. Dabei wurde von Korg nichts vorgegeben.


KORG’s nutekt NTS-1 is a fun, little kit – and open to ‘logue developers

KORG has already shown that opening up oscillators and effects to developers can expand their minilogue and prologue keyboards. But now they’re doing the same for the nutekt NTS-1 – a cute little volca-ish kit for synths and effects. Build it, make wild sounds, and … run future stuff on it, too.

Okay, first – even before you get to any of that, the NTS-1 is stupidly cool. It’s a little DIY kit you can snap together without any soldering. And it’s got a fun analog/digital architecture with oscillators, filter, envelope, arpeggiator, and effects.

Basically, if you imagine having a palm-sized, battery-powered synthesis studio, this is that.

Japan has already had access to the Nutekt brand from KORG, a DIY kit line. (Yeah, the rest of the world gets to be jealous of Japan again.) This is the first – and hopefully not the last – time KORG has opened up that brand name to the international scene.

And the NTS-1 is one we’re all going to want to get our hands on, I’ll bet. It’s full of features:

– 4 fixed oscillators (saw, triangle and square, loosely modeled around their analog counterpart in minilogue/prologue, and VPM, a simplified version of the multi-engine VPM oscillator)
– Multimode analog modeled filter with 2/4 pole modes (LP, BP, HP)
– Analog modeled amp. EG with ADSR (fixed DS), AHR, AR and looping AR
– modulation, delay and reverb effects on par with minilogue xd/prologue (subset of)
– arpeggiator with various modes: up, down, up-down, down-up, converge, diverge, conv-div, div-conv, random, stochastic (volca modular style). Chord selection: octaves, major triad, suspended triad, augmented triad, minor triad, diminished triad (since sensor only allows one note at a time). Pattern length: 1-24
– Also: pitch/Shape LFO, Cutoff sweeps, tremollo
– MIDI IN via 2.5mm adapter, USB-MIDI, SYNC in/out
– Audio input with multiple routing options and trim
– Internal speaker and headphone out

That would be fun enough, and we could stop here. But the NTS-1 is also built on the same developer board for the KORG minilogue and prologue keyboards. That SDK opens up developers’ powers to make their own oscillators, effects, and other ideas for KORG hardware. And it’s a big deal the cute little NTS-1 is now part of that picture, not just the (very nice) larger keyboards. I’d see it this way:

NTS-1 buyers can get access to the same custom effects and synths as if they bought the minilogue or prologue.

minilogue and prologue owners get another toy they can use – all three of them supporting new stuff.

Developers can use this inexpensive kit to start developing, and don’t have to buy a prologue or minilogue. (Hey, we’ve got to earn some cash first so we can go buy the other keyboard! Oh yeah I guess I have also rent and food and things to think about, too.)

And maybe most of all –

Developers have an even bigger market for the stuff they create.

This is still a prototype, so we’ll have to wait, and no definite details on pricing and availability.


Yep, still waiting.

Wow, I really want this thing, actually. Hope this wait isn’t long.

I’m in touch with KORG and the analog team’s extraordinary Etienne about the project, so stay tuned. For an understanding of the dev board itself (back when it was much less fun – just a board and no case or fun features):

KORG are about to unveil their DIY Prologue boards for synth hacking


Sounds and stuff –

Interviews and demos –

And if you wondered what the Japanese kits are like – here you go:

Oh, and I’ll also say – the dev platform is working. Sinevibes‘ Artemiy Pavlov was on-hand to show off the amazing stuff he’s doing with oscillators for the KORG ‘logues. They sound the business, covering a rich range of wavetable and modeling goodness – and quickly made me want a ‘logue, which of course is the whole point. But he seems happy with this as a business, which demonstrates that we really are entering new eras of collaboration and creativity in hardware instruments. And that’s great. Artemiy, since I had almost zero time this month, I better come just hang out in Ukraine for extended nerd time minus distractions.

Artemiy is happily making sounds as colorful as that jacket. Check sinevibes.com.

Die Korg-Familie bekomme neue Oszillato(h)ren: Das andere FM von Sinevibes


Sinevibes ist der Hersteller bzw. Bent ist der Name bisher zweier Angebote für Prologue und Minilogue XD von Bent. Sie erweitern den digitalen Oszillator-Bereich.

Schon lange waren Oszillator-Modelle für die Korg-Synthesizer angekündigt und von Mutable bereits auch geliefert. Und dann gibt es noch einen Anbieter namens Bent. Von dort kommen jetzt schon zwei Angebote:

Zeitkonstantenkompensatoren neu kalibrieren!

FM gibt es eigentlich ja jetzt schon, dennoch gibt es von Sinevibes die Bent Oszillator-Modelle. Das Besondere ist nicht nur die FM selbst, sondern die Verbiegung der beiden Oszillatoren innerhalb dieses Modells. Sie verformen die Kennlinie und Charakteristik sowie Phasenlage und Zeitsymmetrie. Als Schwingungsformen sind fünf verschiedene vorgesehen, die allesamt Symmetrie-Modulation zulassen und „Harmonic Balance“ justierbar macht.

Die Qualität und „Auflösung“ dieses Effekts soll sehr hoch sein. Ein langsamerer LFO bis 10 Hz ist ebenso verbaut. Eine AD-Hülkurve ist auch vorgesehen.

Neben diesen gibt es auch nocht das „ältere“ „Turbo“-Modell, das ebenfalls FM-Sounds generiert. Auch hier ist eine kleine AD-Hüllkurve verbaut und die hohe Aufllösung ist hier ebenfalls über dem der normalen Synthesizer.

Die Möglichkeit für eigene Oszillatoren-Modelle begann mit dem Prologue und ausgegebenen DSP-Boards und wurde durch den Minilogue XD erweitert. So kann der dritte Oszillator deutlich mehr. Der Code ist eigentlich gleich für die bisher zwei Synthesizer.

Weitere Information

Korg forderte auf, dass Hersteller sich dessen annähmen und sie haben es auch getan. Aktuell gibt es beide auch als Bundle für 49 Dollar. Mehr dazu findet man auf der Website von Sinevibes.


KORG’s minilogue xd is a new 4-voice synth with the best of the rest

KORG are introducing the Minilogue xd. It’s not just a Minilogue with some extras: it’s a new polysynth with the best bits of all the KORG analog range, including the prologue flagship, in a compact package.

It’s like the hatchback of synths – the compact, mid-range priced synth that might just wind up being everyone’s favorite. It’s poised to be the Golf GTI of electronic instruments.

It’s in the compact monologue form factor, with a US$649.99 price. And it’s coming soon (this winter, so… at least “before spring”).

To be honest, I loved the original of this series, the minilogue. But then with each new iteration, KORG added something new that made me want a combination of all the other synths.

And now, sure enough, what do we get? A combination of all the other synths.

From the minilogue: the elegant 4-voice polyphonic voice structure and voice modes that made the original so terrific.

From the monologue: the 16-step sequencer and microtuning features (thanks Aphex Twin!), plus that cute little form factor.

From the prologue: the MULTIdigital oscillator, plus new effects.

I’m sure some people will gripe because they wanted the extra keys and size of the minilogue, but otherwise this looks like the perfect KORG synth.

Reverb, delay, and modulation, plus two CV IN jacks complete the package.

Hilariously that “XD” of course also signifies “lol,” which may be how you feel if you just sold off a monologue or minilogue and now can buy up a combination of the two. (As with Windows XP, KORG are using the lowercase xd to de-emphasize that a little…)

Sing along:

Obligatory! Demo! Video!

Prologue und Minilogue XD bekommen Mutable Plaits Oszillator-Modelle für den Digital VCO

Mutable PlaitsMutable Plaits

Korg hat vor einiger Zeit ein Entwicklerkit und offener Schnittstelle präsentiert, jeder darf und kann für den digitalen Oszillator neue Modelle bauen. Das hat Mutable jetzt getan.

Plaits ist die Verbesserung des bekannten Oszillators von Mutable Instruments. Es beherrscht verschiedene Synthesegrundlagen von Physical Modelling bis zu Drum-Sound-Modellen aber auch FM, Sync und Standard-Oszillatoren. In die Korgs finden allerdings nicht alle Modelle Einzug, sondern „nur“, jene für die genug Platz ist. Das sind:

va – Klassische Wellenformen – ein normaler Oszillator
wsh – Waveshaping
fm – Zwei FM-Operatoren
grn – Granular Formant Oszillator
add – Harmonic Oszillator
wta – Wavetable Oszillator (Aufgeteilt auf 4×8 Oszillator-Modelle wegen Speicher-Begrenzungen)

Wir gehen schwer davon aus, dass der Minilogue XD dieselben Möglichkeiten wie der Prologue haben wird. Das frei erhältliche Entwicklerkit kann jeder herunterladen und die Modelle einladen kann jeder kostenlos tun und mit Korg „Upload Software“ in den Synthesizer verschoben werden. Der Download der genannten Modelle ist auf Github  möglich.

Ja, ganz offensichtlich kostet das alles für uns Nutzer gar nichts.

Korg ist offensichtlich etwas gelungen, was nun die ersten Früchte trägt. Zudem darf jeder seine Modelle und Programmierkünste anwenden und, so wie Mutable, ins Netz stellen. Das kann noch spannend werden und wenn Korg die Plattform „Digital-Oszillator“ ausbaut, wird die Menge der Nutzer schnell größer.


Turbocharge KORG’s Prologue synth with Sinevibes

Synth hot-rodding? Earlier this year, KORG introduced the notion of their synth as extensible platform, by adding an SDK for their Prologue polysynth. The only question was, what would developers do with it – and now we get one answer.

Sinevibes, the small shop of Ukrainian developer Artemiy Pavlov, has been known for clever, elegant Mac plug-ins (even if there’s a lot more). But Artemiy has decided to embrace hardware as one of the first developers for KORG’s Prologue synth. And the results are unique and lovely, letting you transform the oscillators on KORG’s instrument with new spectrally satisfying waveshaping oscillators.

Basically, it’s a plug-in for your hardware.

Here’s what you get:

Juicy, edgy wavetables are the order of the day. Specs from Sinevibes:

  • Two sine oscillators with variable balance, frequency ratio and beating frequency.
  • Five different waveshaping algorithms with continuously variable curve complexity.
  • Built-in lag filters for noise-free, ultra-smooth parameter adjustment and modulation.
  • Built-in envelope generator with widely adjustable attack and decay times (1 ms to 10 s).

Check it out, or buy it for just US$29, with full manual and example patches:


It’s interesting – we live in a music tech industry that benefits from small scale and diversity. Now, this model is well known in Apple’s App Store, but sure enough that hasn’t necessarily been a no-brainer for independent music developers. So, instead, we see creative music engineers developing for Eurorack (which frees them of the burden of making complete enclosures and power supplies, and lets them interoperate with an ecology of a bunch of manufacturers). Or we see them continuing to see plug-in development as paying for their time – especially with new opportunities like those afforded by software modular environments. And now KORG are in the game with hardware plug-ins.

What’s changed in part is the expectation of reducing development overhead but targeting more varied platforms. So you might make a plug-in for a software modular (VCV Rack, Cherry Audio Voltage Modular), and port it as a Rack Extension for Reason, and then ship the same algorithm for use on KORG’s hardware – or some other combination.

It’s encouraging, though, that in a world where consolidation rules, music tech remains weird and fragmented. A company like KORG will ship a lot of synths – but it’s great that they might also support a tiny or one-person developer, by letting their users’ customize their instrument to their liking. And it means you get a Prologue that might be different than someone else’s.
