New Kodamo Mask1EX MK2 Bitmask Synthesizer ~ Jade Vine Limited Edition

video upload by Kodamo

"The Mask1EX desktop synthesizer is back, with new looks and new features! Mask1EX MK2 offers 14-voice polyphony with two Bitmask oscillators for each voice - Bitmask Synthesis is exclusive to all Kodamo's Mask synthesizers, it produces a wide range of unique tones by using a single number as parameter. Mask1EX MK2 also has built-in effects, a looper, an arpeggiator and much more."



"It is back, with a totally new design, more powerful than ever! The Mask1EX is a desktop synthesizer that you can use with your keyboard, DAW, sequencer or any other gear with MIDI. Like other Mask synths, it is based on our exclusive Bitmask synthesis technology which generates up to 512 different waveforms for oscillators. It offers 14-voice polyphony with two Bitmask oscillators per voice and 2x2 parts of multi-timbrality (two parts of single or dual layered voices). Each part comes with stereo effects to make the sound warm and rich, plus a master effect with delays and reverbs. Like the Mask1 keyboard, the Mask1EX MK2 offers an incredible playing experience with its dynamic articulation system. Try the slurred, poly-mono and hybrid modes, they add a new dimension to keyboard playing, changing how the sound behaves as you play legato, staccato, neighbor notes or wider intervals.

Mask1EX MK2 is powered by USB-C and is extremely efficient with 1.5W of power consumption, which makes it easy to power by a battery, laptop or smartphone. USB supports class-compliant Audio and MIDI. We also included good old DIN MIDI ports for compatibility.

Mask1EX MK2 offers high-end features at a fair price, with balanced stereo outputs, 200 memory slots for your own sounds, 377 factory presets, full CC mapping of all synthesis parameters, customizable velocity and aftertouch curves, and a lot more.

Inspiration does not wait, so we optimized the Mask1EX MK2 to be extremely quick at startup, it starts in 0.5 seconds. Press ON and play! And it remembers the last sounds you used.

This Jade Vine limited edition gets you a stylish turquoise steel enclosure and a colorful front panel.

Your unit is fully assembled by hand in France, except for surface-mount electronics.

What's in the Box:
Mask1EX MK2 synthesizer

Printed quick start guide (refer to MASK1's user manual for detailed operation)
USB Power supply with EU, UK, US/CA/JP and AU/NZ plugs. If you have no matching plug for your country, you have to use your own power source. Any phone charger or device with USB port will work.

Genius or Insanity ... The Synth That Nearly Broke My Brain!! Kaleidoscope Review and Demo

video upload by Starsky Carr

0:00 intro
1:05 the interface
5:00 Envelopes… they drive the sequencer
7:55 Sequencer Patterns and Lengths
9:33 A note on Modulation
11:10 Quantisation, MIDI, BPM, voice modes
12:06 MIDI Control
13:22 Load/Save
14:10 Genius or Insanity?

"In this deep-dive demo and review, I break down what this mad-looking, semi-modular digital synth actually does — and more importantly, how to use it musically. Combining additive + subtractive synthesis, generative sequencing, and BPM-linked envelope timing, this thing is capable of everything from controlled melodic patterns to chaotic, evolving textures.

If you’ve ever wondered how far modern digital synthesis can go — this is it.

Rather than just listing features, this video explains the concept behind Kaleidoscope — how its AD envelope “period” drives sequencing, how voices interact, and how you can build complex evolving patches from simple ideas.

🔥 What You’ll Learn
How Kaleidoscope’s generative sequencer actually works
The role of AD envelope periods in rhythm + timing
Creating evolving patches using voice interaction + end-of-cycle triggers
Using additive, subtractive & wavefolding synthesis together
How modulation, quantisation, and patterns shape musical output

🎛️ Key Takeaways
This isn’t a typical synth. It’s closer to a self-evolving modular system in a box, where:

Timing is musical, not arbitrary
Events trigger other events
Chaos can still stay in key

As mentioned in the video, this is not beginner gear — but if you like to go deep, it’s incredibly rewarding"

Free Behringer CZ-1 online editor

video upload by gary909

via gary909:

"I've finally finished my Behringer CZ-1 editor, which is available online for free:

https://www.behringer-cz1-editor.co.uk/

This editor has taken me forever to complete! It's by far and away the most advanced one I've built yet, featuring 90 or so sliders. I'd had no experience with Phase Distortion Synthesis before starting this project, so it meant reading a few books and watching hours of you tube videos. There's bound to be a few bugs, but it beats using the single button on the hardware to program the unit.

The UI has also been designed to shed some light on how to program it, with panels being highlighted when accessible, and animations to convey what is being changed. Hopefully it should help somebody. Every control has it's function listed, you just need to hover the mouse over it.

Here's a short youtube video going over some of the features.

It's completely free and works through the browser, you just need to plug in your CZ-1 into your pc or phone. Safari unfortunately isn't supported because Apple doesn't allow midi data transfer, but it should work well on most other platforms."

The Crow Hill Company Introduces the THE SH*T SYNTH

The Sh*t Synth - Walkthrough video upload by CROW HILL XTRAS

Press release follows:


The Crow Hill Company turns to extensive and rare collection to turn out THE SH*T SYNTH as compendium of 48 circuit-, wave- and sample-bent instruments

EDINBURGH, UK: The Crow Hill Company is proud to turn to its own extensive and rare collection of hardware to turn out THE SH*T SYNTH — available as a compendium of 48 circuit-, wave- and sample-bent instruments inspired by some of the Edinburgh-based enterprise’s eclectic musical favourites (spanning the likes of Aphex Twin, Boards Of Canada, Joe Maus, Jon Brion, Laurie Spiegel, Radiohead, Throbbing Gristle, and Yazoo) to create something that they collectively ask: is it just shit or ‘the shit’? — as of April 7…

Whatever way anyone chooses to read into the titling of THE SH*T SYNTH as the latest entry into The Crow Hill’s ongoing ORIGINS series of sample-based virtual instrument plug-ins, one thing is for sure: it readily represents a broad selection of three categories of 16 workhorse instruments each, effectively wrapped up into a single plug-in designed to bring a cohesive approach to making music more edgy, lo-fi, retro, and — swimming against the technological tide of so-called progress — decidedly AI (Artificial Intelligence) slop-free. From pianos to strings, plucks, beeps, bass, and pads, the compendium that is THE SH*T SYNTH has been lovingly sculpted by the Edinburgh-based enterprise’s media composer and ‘samplist-in-residence’ Christian Henson to take the hassle out of making existing sounds less refined, catering to those looking for an entirely new bank of Mellotron-style sounds as well as synths that have been long forgotten — for good reason, too!

Korg Phase8 Sequenced by Ableton Live in the Context of a Film Score

video upload by Genshi Media Group

"::| TO HEAR THE FULL RANGE OF FREQUENCIES AND STEREO EFFECTS, A GOOD PAIR OF HEADPHONES IS HIGHLY RECOMMENDED |::

As the title states, I just wanted to show how you can sequence the ‪@KORG_INC‬ Phase8 with ‪@Ableton‬ Live. I used three MIDI tracks to sequence the Phase8, with each MIDI track played live into Ableton via my Waldorf Quantum (as my main controller.) I also added some quick, rough film score elements towards the end to show the Phase8 in a full musical context."

"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.

Analog oscillators hit different: exploring the SED-CSM and QSQ

video upload by SynthDad

"I dive deep into the raw sounds and harmonic richness of the SED-CSM, a complete analog synth voice from Rides in the Storm. With its dual oscillators, sub-octave generator, ring modulator, and a dedicated noise source, this module provides a massive foundation for everything from earth-shaking bass to evolving drones.
SED-CSM has two LFOs which can go into audio-rate, reaching up to 6.6 kHz and a VCF equipped with a dedicated overdrive switch. The SED-CSM offers endless possibilities for aggressive textures and squelchy, acid-inspired leads.
Complementing this is the QSQ; an 8-channel performance sequencer and MIDI-to-CV interface that serves as the brain of the operation. I show how the QSQ’s 16 analog-style rotary encoders allow for intuitive, hands-on melodic creation. Leveraging features like Euclidean rhythms, per-step probability, and integrated LFO/envelope generation, the QSQ compliments SED-CSM’s raw oscillators.

Luna is the most LOGICAL synth in the world

video upload by Oscillator Sink

"The Luna from Neutral Labs is an instrument built on binary logic.

Taking inspiration from the DIY Lunetta synths of the 70s and 80s, Luna’s core architecture is built using CMOS chips, square waves, logic gates and binary processors. Its design leads to a semi modular instrument where rhythm is just harmony slowed down. Oscillators can be clocks, and the logic gates and binary processing modules can be involved in modulation and sequencing, or as audio processors depending on how fast you work them.

Luna supplements these binary ideas with a number of additional features which take it beyond the Lunetta synths of old, like pitch quantization with multiple scales, pitch sequencing, MIDI control and digital effects, as well as a three channel output mixer with low-pass gates.

In this video I’ll go through the various fundamental sections of Luna, demonstrating how they can be used to influence the synth, both at sub-audio-rate for sequencing and modulation as well as at audio-rate as sound processors, and then move on to a few full patches to explore how everything operates together. Throughout the video I’ll scatter a few other patches of various types to give you an idea of the range of the Luna in different musical settings.

Transparency notice: Neutral Labs Kindly sent this instrument over to me for free for the purposes of making videos about it."
