There's a New Plugin That Uses Wavetables as Spectral Filters — Wavefield by Fine Increments

video upload by Keith Crosley

"Two new uses for wavetables today — and neither is synthesis. First: smallcircles.net/waveforms, a web tool by KRC Mathwaves user Quentin that renders any audio file as stacked ridgeline plots — instant Peter Saville/Joy Division "Unknown Pleasures" album cover art. (Fun fact: the cover visualizes radio pulses from pulsar CP 1919, originally plotted by Harold Craft Jr. for his 1970 Cornell PhD thesis.) Second: Wavefield from Fine Increments, a brand-new spectral filter plugin by Seth Watson that turns wavetable frames into FFT gain curves — three modes (Magnitude, Spectral IR, Phase Warp), tempo sync, stereo spread, and wavetable import. We also drop Wavefield into a Bitwig delay feedback chain for spectral delay, feature Authentic Soundware's new Space Age Colors library, and close with Liminal Space reverb for that Blade Runner/Lexicon 224 vibe. So grab your spectral filter and hold on to your pulsar for this wavetables-a-go-go episode of your favorite talky synthesizer content show!

via Tonetweakers

"Univox Mini-Korg Synthesizer 700 For Sale. This Minikorg has been meticulously refurbished by perfectionists and is in perfect working order and ready to play.

This unit has some very useful modifications that expand its capabilities.

Adjustable Resonance
The stock minikorg just has a single switch for resonance boost, but this one's got 2 additional rotary pots added for variable resonance of the high pass and low pass filters - it really lets this minikorg scream! This mod alone is a huge improvement over a standard minikorg.

Filter Input
There's also an audio input allowing one to process external sounds through its filters.

Adjustable Chorus Rate
There's a pot to adjust the rate of chorus 1.

Octave and Waveform Mixing
These mods give you the ability to mix waveforms and octave divisions, resulting in a fatter sound. These mods are a bit strange and interact with the octave and waveform switches, so they take a little getting used to.

These additional octave and waveform pots are active at the very top of their range and are more like switches and are sometimes inactive, depending on your settings. Sometimes octave switch settings will cause a drop in volume if the appropriate knobs are not adjusted, and sometimes there will be a change in timbre of the selected waveforms if the knobs are not adjusted properly. It's a bit confusing at first. We can probably remove these mods for you if you'd like so the octave and waveform switches work as they normally would in a stock unit, but this will remove the ability to mix waveforms and octave divisions - please email us to discuss if you'd like these mods removed (we would just remove the wires connecting the mods, not the additional pots).

These mods give this minikorg more sonic possibilities than a stock unit and add value to this example.

We paid our tech for 5 hours of skilled labor to get this unit working great again. In addition to fixing any problems, he did the following servicing:

Cleaned jacks
Replaced all power supply electrolytic capacitors (he says someone previously replaced the other electrolytic capacitors)
Replaced fuse
Cleaned and lubed all pots
Calibrated VCO"

ellitone - lil' dream organ - (small batch)

video upload by ellitone instruments

"*small batch - only 7 available -

ellitone.com

The ellitone lil' dream organ is a limited edition battery-powered polyphonic digital synthesizer with built-in amplified speaker.

Featuring 8 wooden Touch Bars, 16 oscillators, 8 selectable musical scales, and a collection of 50 waveforms to explore and blend using the ‘infinite tone’ knob. the lil dream organ is a fun and powerful electronic instrument capable of many tones and textures, simple enough for a youngster or beginner to operate.

Controls:

-‘infinite tone’ knob blends and mixes 2 separate layers of waveforms together. Each layer consists of 8 oscillators and each layer has its own unique selected waveform. As you turn the knob fully clockwise or fully counterclockwise, a new waveform is chosen from a collection of 50 waveforms and applied to one of the 2 layers. This means that you are infinitely blending in-between new combinations of waveforms continuously.

-musical scale select switches. 3 toggle switches at the top of the device are used to select one of the 8 musical note scales. These three switches operate using binary logic. With 3 switches, we have 8 unique combinations of switch positions (on/off/on…off/off/on…etc). Each one of these 8 possibilities selects a different musical scale to explore using the wooden Touch Bar keyboard notes.

A Demo of mods driving the TastyChips Integral dual convolver pedal

video upload by ParadisoModular

"As I recently finished modifying my 'Integral' dual convolver pedal by TastyChips (https://www.tastychips.nl/) to accept control from multiple external CVs and gates, here's a quick demo video. After a few minutes of showing the Integral's front panel being driven by my external CVs, I switch to showing more detail on my mods and the patch that runs it. This patch also gave me a chance to explore my TipTop Matrix Sequencer, where you dial in 16 pitches from which you can extract 10 sequences that traverse the note matrix in different ways. I crossfade periodically between these 10 lines driving different tone sources (reversing them occasionally to give a bit of variety) - this provides a dynamic and harmonically-rich base upon which to run the Convolver, which produces all of the effects that you hear.

My mods let me turn essentially all of the knobs with external voltages (I also have a gate input for the 'shift' button so I can get at the secondary functions of these knobs too), and indeed, I do that here. All of the knobs are being turned constantly by different LFOs. This pedal sports two convolvers - the panel's knobs affect the one that's displayed, but also I provide a periodic pulse to the 'select' knob (which I gated in the pedal so it doesn't hit when 'shift' is active to avoid going into a menu), which toggles control to the other convolver. So this patch, simple as it is, spans a lot of sonic space...

The Integral is a wonderful box - it sports two convolver chains, and you can select from circa 100 different impulse responses (plus add your own via a USB stick). Convolution is a general operation that spans across reverb, echo, filtering, etc. - you essentially inherit the character of the chosen impulse in the driving waveform. It's not a real-time operation in principle (the convolution integral for each sample goes across the entire impulse) although there are ways of speeding and breaking the operation up to approach real time (plus this pedal allows you to window the integration over the stored impulse). It's a very deep pedal - and in using it, I saw right away how turning several of the knobs at once can get you to interesting modulations and textures while they are moving (the expression input gives access to only one parameter - I use it now for the convolution cross-fade, as I couldn't get to that input with my mods). TastyChips used to make a Eurorack module giving some of this flexibility, but it only included one convolver. The Integral pedal has 2 and is a current product, hence reinforcing my decision to acquire one and essentially 'turn' it into a versatile synth module.

My sequences here are a bit major-key/unsophisticated (all notes have to work potentially on top of each other and in whatever sequence it picks), and the pedal occasionally gets briefly into strange territory - hence this demo only hints at where this beast can go (every impulse response has a different character too). And turning all of the knobs can occasionally push it into instability - I will probably use fewer when I take it out for a real spin. More coming with this one in future patches, but in the interim, here's this trial demo..."

New Blukač Fractalist - Sound Samples Ep. 1

video upload by Blukač Instruments

"In this sketch, we demonstrate how a pair of Fractalists is working together in a timbral progression.

The left one is responsible for the bass sound, where, with each iteration, the waveform is unfolded, becoming more and more complex and rich in harmonics.

It is also modulated a bit with a built-in LFO patched into the WARP input to add some movement.

The right one produces a percussive part. The actual base frequency is very low, and with a standard oscillator, there will be no sound or only a rumble. Here is a different story. As the generated waveform is very complex and contains a lot of harmonics, they become audible as rhythmic patterns.

With each iteration, this effect is more prominent. WARP is not modulated to have this specific pattern to be fixed, but if you were to change it, there are a lot of different patterns to look for. In future episodes, we will explore this in more detail.

Audio is intentionally captured raw, without any filters, VCAs, or effects."



via Perfect Circuit

Fractalist from Blukac is a unique digital oscillator that creates complex waveforms and rhythmic undulations using fractals, generating captivating sounds that evolve and grow into digital chaos. Start by selecting a core waveform, either triangle or trapezoidal, and expand its fractal dimension with the Iter control to create iterations on this shape, adding harmonics to the sound that bloom in digital bliss. Through all these fractal transformations, Fractalist's output maintains its periodicity, with a Frequency control that can be used to shift in octaves, semitones, or fine-tuned between notes. At low frequencies, Fractalist becomes an oddball rhythm machine, churning its mathematical movements in unique patterns according to the waveshape created through fractal expansion.

Select your desired degree of digital artifacting with the Alias switch, inviting or omitting the unique sounds of system failure as your harmonics grow beyond the bounds of Fractalist's digital structure, folding frequencies back on themselves for inharmonic results. The onboard Warp control can be used to further modulate the timbre of your sound, alongside dedicated inputs for frequency modulation and hard Sync. Finally, a saturating boost is available to add heat to the cold digital output, while a friendly adjustable LFO provides an onboard source for modulating Fractalist's bevy of CV inputs. With its unique synthesis engine and plentiful opportunities for creative patching in a broader Eurorack environment, Blukac's Fractalist is sure to expand your sound palette, and perhaps, your mind.

"The power of modular is flexibility, but I've never been a fan of having to buy a lot of utilities just to get going! The cost of a little setup skyrockets as soon as you start adding the basics, so I honestly love the fact that getting a b:ond (here in the v2, the new version) just gets you going as soon as you put it in the case.
Two oscillators, 4 VCAs, suboscillators, waveform morphing, FM (through zero!), PM, sync, mixing... everything is just ready to play and enjoy.

Modular for the Masses

Nyquist Nightmare

Audio Mangling Modulator/Demodulator

This module is a modulator/demodulator. The top four knobs interact with each other to take a signal and mangle it beyond all recognition, or if you're patient and lucky, let the signal come through mostly unchanged.

What is going on there? you ask. The input is used to frequency-modulate a VCO that can oscillate beyond anybody's hearing range. The resulting (possibly ultrasonic) signal frequency-modulates a second identical VCO. This leads to the kind of signal degradation you might expect from an AM radio transmission. Or a short wave signal fighting its way through a hurricane.

The rest of the knobs control filtering; high-pass to remove the truly ground-shaking rumbles the top for knobs can generate, and resonant low-pass to get the harsh high pitches out of the signal, and emphasize (for example) the frequency range of human speech, if you want to pass old movie dialogue through this.

Also included are a wet/dry control (while prototyping this module I would sometimes spend minutes looking for the perfect knob settings to allow a signal through just to realize the signal source had stopped playing), a CV input for the low-pass filter with an attenuator knob, and a effect volume knob.

Some fun things to try:

with zero input, try to get a modem sound!
connect a simple waveform and massage the top four knobs to fold the wave in surprising ways
David Lynch. Put David Lynch through this.
turn the resonance of the low-pass VCF up and use this as a VCO (not 1V/oct, I'm afraid
Turn both "Carrier" knobs all the way down, so the VCOs are stalled, and listen to the signal bash its way through

New module! Dual Retro Vco

video upload by Radical Frequencies Modular

"Listen the new Radical Frequencies Dual Retro VCO playing an arpeggio , showing all waveforms and making Pulse with modulation and Hard Sync between the vcos . It goes through the RF Mixer and then to Diode Dream Vcf as it suits this oscillator perfectly! #eurorack #modularsynth #radicalfrequenciesmodular #dualretrovco #drvco #diodedreamvcf #analogsynth"

"Handmade Dual VCO of discrete core capable of internal FM cross modulations - Hard sync and Ring Modulator

• Analog discrete saw core oscillators with Saw, Pulse, Triangle and Ring Modulation wave outputs.The sound is warm and fat, emphasizing odd harmonics for this big retro sound. My purpose here is to approach the sound of classic synths from 70s, that we all loved.
• The SAW wave produces rich bass frequencies, sweet mids and smooth highs but overall, it is still well balanced across the full frequency range. The Triangle wave is almost perfect in shape with no buzzy hum sound. The pulse wave can produce that chorus-like phasing effect, when using an LFO to modulate the PWM input and does so in a very unique way, as it changes the phase of the signal as well.
• Two identical VCOs : VCO ALPHA and VCO BETA, with the ability of hard sync as each VCO syncs internally with the other. Using the attenuator knob for SYNC, you can go from zero to soft sync(11-12 o’clock) to hard sync when the knob is fully CW. For syncing you just need to turn CW, the sync knob of the VCO you want to be the slave. Don’t open both the sync knobs at the same time unless you want to make some weird sounds.
• There are external sync inputs for each VCO as well. External oscillators can be used as masters, just feed the output of the oscillator of your preference, into the sync input or either ALPHA or BETA. Just remember to feed a saw or a square wave, into the SYNC input. This is very important in order to sync the oscillator. A ramp wave it will not sync at all! (The RF DPVCO for example is a ramp out VCO and if you want to use it as master you must invert the signal first.)
• Both ALPHA and BETA track 5 octaves accurately, tempco resistors are attached to the tuning ICs CA3046 on both VCOs.
Separate voltage regulators for each oscillator can achieve the best sounding results without drift or bleed pitch, between VCOs.
• Both VCOs go from a relative fast LFO range with the coarse tuning knob fully CCW, up to high frequency oscillation.
• Octave Switches of 3 positions: 1 octave down - , zero , 1 octave up +, are available and make patching, fast and intuitive.
• There are internal normalisations for exponential as well as linear FM and both have independent EXP FM and LIN FM, attenuators.
• You can select the wave for the internal FM buss via the front panel switches .Options are Triangle and SAW. The internal FM wave, is independent per VCO as well.
• There are also internal normalisations for PWM, where each VCO modulates the pulse width, of the other and both use the triangle waveform.
• There is a PW offset, per VCO - negative phase pulse width at CCW to + positive phase at CW and 50-50 duty cycle square wave, in the middle of the knob.
• Ring Modulation section is a separate feature where X and Y inputs are internally connected with the VCOs as well. It has 2 inputs, X and Ψ and one out, RM. The inputs are internally connected to the internal FM buss switch of triangle - saw selector.
VCO ALPHA is internally connected into Ψ input and VCO BETA, into X input. You can feed the RM inputs any wave you desire from other VCOs as well .
• An external patch cable breaks the normalisation of all internal connections, via input jacks. (EXP FM, LIN FM, PWM, SYNC, X Ψ)

• Important note about tuning : The vcos need at least 30 minutes warm up before using it for good tracking. Also when you have to tune the vcos it’s better the octave switches to be in the middle position and all the fm and sync knobs must be closed (CCW)

• Large range of sounds with countless sweet spots - ultra stable tuning for FM sounds by using the FM and SYNC knobs simultaneously - fat basses, classic leads and drones. Feed the DRVCO into a good filter and you will enjoy it as it was meant to be! The VCF that I suggest is the RF Diode Dream VCF as it is a ladder filter and suits it perfectly! Of course any other filter of your taste can be used with great results."

What the fork is Waveshaping? | Modular Classroom | Lesson 05

video upload by Cinematic Laboratory

"I've been doing modular since 2018 and now I finally think I may have figured out what waveshaping could be. So by all means this is not some 'masterclass' where I teach you, it's learning as I go and recording it on video. The main takeaway from all this, is that waveshaping is not a module or something you'd do, it's something that happens when certain circumstances align. By definition, waveshaping is 'a non-linear transfer producing new harmonics' which kind of sums up nicely why it's so hard to put your head around it. It becomes much easier once you realize you need to listen for it, it's the result. Not the tech, process or recipe.

And how about 'folding'? As far as I know, wavefolding belongs to the waveshaping family, but instead of clipping the tops off, you'd mirror them back into the waveform. In waveshaping, 'transfer functions' are called 'shaper functions' because a 'transfer' is hijacked by systems theory and we're doing music and synthesis while leaving science in its own domain.

I'll mostly be using Serge gear in the classroom series, but you can already start shaping with a pre-amp with plenty of gain. Just push a sound to a loudness your case or ADC can't handle. Then you can figure out if it's cool to get dedicated tech for it. Hopefully you'll learn that waveshaping is not just distortion :)."

Kurzweil K2061/K2088 Tutorial: Juno-60 Analog Expansion (part 1)

video upload by Kurzweil Music Systems

"In this video, we take a deep dive into the Kurzweil K2061/K2088 and explore creative V.A.S.T. programming inspired by the legendary Juno-60 sound.

This is Part 1 of a two-part series. We’ll build the patch you heard at the beginning completely from scratch, using only a single saw wave as our starting point.

Rather than recreating a vintage synth directly, this patch expands on the Juno’s classic single-oscillator architecture — demonstrating how Kurzweil’s powerful V.A.S.T. synthesis engine can transform a simple waveform into something far deeper and more expressive.

In this episode, you’ll see how to:
• Design a full synth patch from a single oscillator
• Shape tone using VAST DSP architecture
• Create movement and depth with Kurzweil FX
• Use physical controllers to add expression and performance dynamics
• Push beyond traditional analog limitations while preserving classic character

The goal is simple: show just how much is possible with one waveform, thoughtful programming, and the immense flexibility of VAST.

Genki KATLA - THE VOLCANO SYNTH!! Now Available

video upload by Starsky Carr

"What happens when a synthesizer completely breaks the rules?
In this video, we explore the Genki KATLA — a truly unique polysynth inspired by Icelandic volcanoes, featuring a rotating voice architecture, hybrid signal path, and some of the most unpredictable sound design possibilities I’ve come across.

This isn’t your typical analog polysynth. Each of the five voices can run independently with different waveforms, octaves, and modulation — creating evolving textures, harmonic movement, and generative-style sounds that feel closer to modular synthesis than traditional keyboards.

🎛️ What makes the KATLA special?
• Rotating voice polyphony (round robin-style synthesis)
• Independent per-voice oscillators & tuning
• Digital oscillators + analog filter signal path
• Looping envelopes reaching audio-rate modulation
• Phase distortion, wavefolding & multiple distortion types
• Tape-style wow, flutter & pitch instability effects
• Stereo voice movement & evolving spatial modulation
• External inputs for processing other gear

From lush ambient pads to aggressive, evolving sequences — this synth can go places most instruments simply can’t. It’s not about recreating vintage sounds… it’s about discovering entirely new ones.

💸 At around €5000, this is definitely not a beginner synth — but for sound designers, and anyone looking for something truly different, it well worth a look."

HUGE thanks to Genki for letting me a part of this with them and showing off this super cool synth.

No money was paid, no agreements were made... these are my real thoughts on this very premium synthesizer and I will be sharing lots more."

Press release follows:


Genki Instruments announces availability of Katla as Voice Rotating Polyphonic Synthesizer inspired by its natural namesake

REYKJAVIK, ICELAND: having twice blown European musical minds thanks to show-stealing showcases at SUPERBOOTH25, May 8-10, Berlin, Germany and Machina Bristronica 2025, September 27-28, Bristol, UK, before adventuring across the pond for a repeat performance at Buchla & Friends 2026, January 24-25, LA, CA, USA, Reykjavik-based instrument developer Genki Instruments is proud to announce availability of the eagerly-awaited Katla as a Voice Rotating Polyphonic Synthesizer inspired by Iceland’s largest subglacial volcano as its natural namesake — readily representing the company’s first foray into analogue synthesis, albeit one that uniquely utilises a set of wildcard parameters to infuse it with organic, unpredictable behaviour as an instrument that is worthy of that legacy, excelling at generating rich, evolving, multi-layered textures, where each note stirs, swells, and erupts in its own distinct way — as of March 31…

Clearly Katla’s inspiration runs through its ‘volcanic’ veins. After all, it is framed by side panels and knobs forged from authentic Icelandic lava, giving each instrument a tangible connection to the volcanic forces that inspired it. That this synth should surely roar is a given. Genki Instruments inevitably chose, therefore, to kit Katla out with four independent distortion destinations, the most unruly of which is a stereo CMOS (Complementary Metal Oxide Semiconductor) Drive effect — a characterful saturation stage, pushing tones from warm and rounded to fractured and snarling.

Cherry Audio Launches Crumar DS-2 Synthesizer

Based on the original 1978 hardware, this value-packed emulation revives the digital control and analog soul of an often forgotten landmark in synth history.

(March 31) Cherry Audio is excited to announce the release of the Crumar DS-2 synthesizer, a virtual instrument that faithfully replicates and significantly enhances the original 1978 hardware synth that was ahead of its time. This release marks the latest collaboration with Crumar Instruments, following last year’s acclaimed Spirit synthesizer, revisiting a groundbreaking Italian synth and infusing it with Cherry Audio’s signature style.

Crumar DS-2 by Cherry Audio is available now for only $59 at cherryaudio.com and through authorized resellers, bringing its rare and legendary “vintage digital” sound to the modern production environment at an exceptionally low price.

The Crumar DS-2 was a unique synthesizer that combined a monophonic Synth engine alongside a fully paraphonic Poly section. The “DS” in its name stood for “Digital Synthesizer,” and it featured two Digitally Controlled Oscillators (DCOs) designed to prevent tuning drift. However, the resulting waveforms were completely stair-stepped, giving the instrument a gritty character and wild harmonics. Together, the two sections provided the DS-2 with a distinct sound that set it apart from both early digital synthesizers and classic analog models.

Building upon the foundation of the vintage hardware, Cherry Audio’s virtual Crumar DS-2 introduces several powerful modern enhancements to expand its creative potential. The monophonic Synth section now includes unison and multi-voice modes, providing panning and tuning options, as well as polyphonic functionality with 4, 8, or 16 voices. The Poly section supports full 32-note polyphony, and DS-2 now features a keyboard split mode in addition to the layered mode.

The Synth section now includes a stair-stepped sine waveform option, and oscillator sync has been added. A third LFO has been introduced, and LFO options now include discrete delays, sync, retrigger, reverse wave, and one-shot capabilities. The five-part LFO Mixer, previously hardwired to specific destinations, now offers six assignable destinations with 33 options each, providing unparalleled modulation flexibility.

The envelopes have been enhanced with an initial delay stage (DADSR) and velocity sensitivity, and now include looping functionality. Additionally, the Poly section now features VCA release control, making it better suited to powerful string-synth sonics. Touch control has been added with four slots and simple click-to-assign functionality, supporting both channel and polyphonic aftertouch with compatible MIDI controllers.

The VCF has been upgraded to include a 12dB 2-pole in addition to the original 24dB 4-pole option, along with polarity and key-follow adjustments. Other enhancements include an assignable bend range, a dedicated mod wheel, and a dynamic arpeggiator that can be applied to either or both sections. DS-2 also offers three customizable effects chains with 20 studio-quality effects, allowing users to arrange, save, and recall their settings. Over 300 professionally designed presets are organized into 14 categories to inspire instant creativity.

Cherry Audio is also offering the Deep Space Preset Pack for DS-2 for only $9.99. This pack includes an extra 100 presets that provide an in-depth exploration of DS-2's sophisticated modulation routing, expressive performance features, layers and splits, arpeggiator, and studio-quality effects.

Crumar DS-2 reflects Cherry Audio’s ongoing dedication to delivering high-quality sound at an unbeatable price, even in uncertain times. Priced at just $59, the DS-2 is an ideal choice for synth enthusiasts who value both exceptional tone and affordability. Furthermore, until April 13th, producers can purchase the Crumar DS-2 as part of Cherry Audio’s “Build Your Own Bundle” options. Customers can select a Pick 3 bundle for $99 (regularly $119) or a Pick 6 bundle for only $149 (regularly $169), allowing you to mix and match any of their award-winning instruments for as little as $25 per plugin.

Cherry Audio’s Crumar DS-2 synthesizer is available for macOS (10.13 or later) and Windows (7 or later) in AU, VST, VST3, AAX, and standalone formats. A free 30-day demo is available.

TEISCO 110F DUOPHONIC SYNTH SN 4790

via this eBay listing

"Dating from 1980–1982, the Teisco 110F is a two-VCO synth with unique LFO features, a wonderful-sounding VCF that can go into self oscillation, a HPF and, unusually, an eight-band filter bank to sculpt the sound further. The LFO can be applied to either VCO, and a control allows you to shape its emphasis to occur near the front or back end of the waveform, or conventionally, in the middle.

The synth also features portamento that can be set to function with every note played or only when notes are played legato, giving you more expressive control over your performance.

In addition, the 110F has ring modulation, white and pink noise, a mixer, two EGs, and three rubber pads (to the left of the keyboard) that can be pressed to apply the vibrato or wow effect at will, to change the VCF cut-off frequency on the fly, and to change pitch up or down.

Perhaps the coolest feature are the numerous LED displays that show signal strength and the green arrows that light up to show signal flow.

And just to repeat, this synth is duophonic, allowing you to play two notes at a time .

CV and Gate connections are available on the front, along with an external input jack. Any instrument plugged in here replaces VCO 2 in the signal chain.

Everything works properly. As shown in the photos, all the LEDs light, as do the arrows. The LEDs light up based on signal strengh; I put everything at maximum to demonstrate that all the LED segments are working, but under most conditions they will not all be lit at the same time. All the knobs and switch caps are original. The three touch pads to the left of the keyboard function as they should. Some owners complain that theirs have become unusable with age. While the pads on this unit are a little hard to press down, they are responsive and work just fine.

The synth has some nicks on the end pieces, as shown in the photos. Overall, the synth presents very nicely and has a clean and bright front panel."

FREE SYNTH: ENSONIQ SD-1 Emulator (by Sojus Records) - No talking demo

video upload by ADL-MusicLab

"Hello everyone!

Here's to you my 'No talking demo' of this FREE emulation of the Ensoniq SD-1 developed by Sojus Records, which brings back to life this iconic synthesizers!

This VST3 plugin is a faithful, hardware-level emulation of one of the most unique digital synthesizers of the early ’90s.

Originally released in 1990, the Ensoniq SD-1 comes from a lineage of evolving Transwave wavetable synthesizers, following the ESQ-1, SQ-80, and VFX series. It combines additive-style waveform layering with powerful modulation, placing it alongside classics like the PPG Wave and Waldorf Microwave in the world of hybrid digital synthesis.

This "MAME-based" VST3 plugin brings the SD-1/32 to life inside your DAW for the first time. Despite being a proof-of-concept, it is already fully functional and incredibly deep.

The demo showcases some of the presets created directly from the engine – from lush pads and evolving textures to digital timbres and analog-style patches. Each patch can layer up to 6 waveforms from the original ROM, shaped by dual multi-mode filters, complex envelopes, LFOs, and an extensive modulation matrix. The built-in effects processor adds classic reverb, chorus, flanging, and delay.

Key features of the plugin include:
• Full VST3 support (Windows & macOS, Intel + ARM)
• Complete MIDI implementation including polyphonic aftertouch
• Full VST automation (all controls)
• Import of original VFX / VFX-SD / SD-1 SysEx files
• Resizable GUI with multiple panel layouts
• Support for original disk images and cartridges
• Optional multi-output routing (main + aux)
• Built-in sequencer support (with original OS disk)
• And much more...

⚠️ Important: This plugin requires original Ensoniq SD-1 ROM files (not included for copyright reasons). Please check the documentation for setup instructions.

⚠️ Note: Due to the nature of the emulation, CPU usage can be high and only one instance can run per DAW session.
