Korg EXB-MOSS Explained: Physical Modelling Power

video upload by Ian Dixon

"The Korg KARMA normally works as a sample-based workstation, but with the EXB-MOSS expansion board installed it gains a completely separate physical modelling synth engine. In this video I explain what the MOSS board is, where the technology came from, and why it matters for Korg Prophecy, Z1, Trinity, Triton and KARMA users.

MOSS gives the KARMA its own Bank F with 128 programs, six extra voices of polyphony and a set of oscillator models that go far beyond PCM samples. I walk through the MOSS history, show how the different models work, and demonstrate electric piano, VPM/FM-style tones, reed, brass, plucked string, sync, analog-style, organ and performance-controlled sounds using the KARMA and my editor.

How to make the Korg Minilogue XD sound like a Roland JP-8000

video upload by MrSynthmania

"Transform your Korg Minilogue XD into a trance legend!

Get the bundle of 16 Oscillator-Models here: https://synthmania.de/produkt/minilog...

Get the iconic Roland JP-8000 SUPERSAW sound as a digital User Oscillator – with the same parameters as the original.

This is part of my complete Bundle with additional 15 powerful User Oscillators for the Minilogue XD and NTS-1 (MKi).

In this video I’m showing the SUPERSAW in a short trance track and walking through some of the custom parameters:

🎛️ Phase – Control the massive width of the 7 supersaw waves
🎛️ Mix – Balance the dry and detuned signals perfectly
🎛️ Brightness – Open up the filter character for piercing leads
🎛️ SubOsc – Add massive low-end to your supersaw patches
🎛️ Octave Switch – Choose between 1 or 2 octaves for the SubOsc
🎛️ Drive – Boost the punch of the sound

Perfect for owners of the Minilogue XD who want classic trance and progressive sounds."

"This oscillator was written from the ground up in C++ for maximum efficiency and sonic uncompromising quality. Instead of simply stacking standard sawtooth waves, the code uses mathematical refinements otherwise found only in high-end plugins:

Original detune behavior: The oscillator calculates the phase behavior of 7 synchronized sawtooths using the exact asymmetric detune ratios of the original Roland JP-8000.

Fully band-limited: By employing optimized band-limited sawtooth algorithms, the sound stays absolutely clean and free of annoying aliasing even in the highest notes.

Analog-modulated filter design: Inside the code runs a cascade of four highpass filters plus a specialized high-shelf EQ based on BiQuad filter structures. This delivers an extremely clean bass range and silky highs.

Fluyt - Felucca synth engines for Korg drumlogue & microKORG2

And via Regroove | RGRV on reddit:

"This is generated code, but mostly with my own code as reference (such as examples, build infra).

Don't want the FM-1 to have all the fun by themselves. Let's join them ..."

via https://rgrvdotnl.itch.io/fluyt-logue

"Fluyt - Felucca's engines for logue

Felucca is an open firmware for the M-VAVE FM-1, a small synthesizer built around a JieLi pi32v2 DSP. Its sound engines are plain integer C, self-contained, and each one is a different way of 'whistling'. Fluyt takes nine of them and ships each as its own KORG drumlogue or KORG microKORG2 unit.

This is based on Felucca and associated FM-1 firmware which is mostly AI-assisted code. Personal examples, units, and build-infra code were used to create these units.

Why Fluyt?
The name is symbolic, as fluyt is a kind of Dutch vessel, mostly used for trade during the 16th century. Just like in the old days, I hope this 'trading' will happen between the communities. And, the word also means whistle."

Side note: Felucca is by Hügelton Instruments. You can find additional posts mentioning Felucca here.

Korg multi/poly: Tangerine Dream PPG Lead Sound

video upload by Ian Dixon

"In this Korg multi/poly tutorial I show how to build a Tangerine Dream-style PPG lead sound from an initial program, using the built-in digital wave tables rather than imported PPG waves.

The patch starts with a choir-like digital wave, then uses a second detuned oscillator, effects, wavetable position and morph settings to get that wider, vocal, classic electronic lead character.

Chapters:
00:00 Tangerine Dream PPG lead demo
00:57 Choosing built-in PPG-style waves
01:45 Shaping the choir-like wave
02:30 Detuning two oscillators
03:16 Chorus, compressor and tape delay

Korg Minilogue meets vintage Oberheim OB-8

video upload by Synthnerd

"I recently restored an Oberheim OB-8 for someone and before handing it back I decided to see how it compared with the diminutive Korg Minilogue. The Korg is new, small, and cheap – the OB-8 is none of those things. But how do they sound together?

The Minilogue is playing an arpeggio through a TC 2290P delay pedal. Both synths go into the Tascam Model 12 with nothing else in the way. Reverb is from a Lexicon MPX1, their mid-range unit from the 90s, which sat just below the PCM series and above the budget MPX and LXP models. No further processing on this, the audio is straight from the Tascam."

Korg EPS-1 – Deep & Powerful Analog Strings Sounds | Rare Vintage Synthesizer

video upload by RetroSound

"Discover the Korg EPS-1, a rare and often overlooked analog string synthesizer from the early 1980s. In this video, I explore its massive, deep and atmospheric string sounds and show why the EPS-1 deserves more attention among vintage analog string machines.

The Korg EPS-1 appeared on the market toward the end of the development of classic analog string synthesizers. While instruments from brands such as Solina, ARP, Roland and Korg are better known today, the EPS-1 remains relatively uncommon and can be difficult to find.

What makes the Korg EPS-1 particularly interesting is its powerful analog string character. The sounds can be incredibly deep, warm, rich and wide, with that unmistakable vintage analog texture associated with classic string synthesizers of the 1970s and early 1980s.

In my opinion, the EPS-1 produces some of the deepest and most impressive analog string sounds of its era. This video focuses on the raw sound of the instrument, its vintage character and the unique atmosphere it can create.

If you are interested in vintage synthesizers, analog string machines, rare Korg synthesizers, 1970s and 1980s analog keyboards, or classic synth sounds, the Korg EPS-1 is definitely an instrument worth discovering."

Oficina de Sonido Clave: A Fun and Portable Drum Sampler with Euclidean Sequencer

video upload by Limbic Bits

"Clave by Oficina de Sonido is a Euclidean Drum machine, a portable musical instrument with a percussion sequencer based on one-shot samples. Its strenghts lay less in complex and deep sound design but rather in fast results, spontaneity, and lucky accidents. I find it really fun to use and it is a great little device to take on stage or for spontaneous jam sessions."

Free Korg NX5R Editor Librarian | Web MIDI Patch Manager

video upload by Ian Dixon

"The Korg NX5R is a very 90s multitimbral sound module, and in this video I demonstrate my free browser-based editor and librarian for it.

The editor runs locally in the browser using Web MIDI, so there is no cloud upload or server-side processing. You can connect to the NX5R, read the user bank, browse factory and user sounds, manage multitimbral parts, edit program parameters, work with filters, envelopes, LFOs, effects sends and oscillators, then save libraries or export SysEx for later.

It is still a beta tool, but it already makes the NX5R much easier to use for sound browsing, patch editing and library management.
