Kodamo EssenceFM MK1 Demo Part 1

video upload by Panu M Savolainen

"I had chance to have Kodamo EssenceFM MK1 for while. After I played this one, I noticed a bit annoying shimmer fx, so couldn’t remove it and re-record. Didn’t record the MIDI notes, just straight to audio. A bit Eventide Space for additional reverb."

Modern Sounds Pluto - Ambient Soundscapes

video uploads by The Pedalboard Orchestra

"A collection of long ambient tracks based on the Modern Sounds Pluto Semimodular Synthesizer and various effets pedal setups."

Playlist:

1. Modern Sounds Pluto Synthesizer – Ambient Demo & Sound Exploration

These are my first "ten minutes" (okay, the video turned out a few minutes longer 😉) with the Modern Sounds Pluto semimodular synthesizer.
🎧Headphones recommended for the full sonic experience.

In this small setup Pluto is accompanied by three pedals, the Strymon El Capistan v1, the Chase Bliss/Goodhertz Lossy and the Eventide Space in ModEchoVerb algorithm, all in stereo.
Pluto, this tiny little box, is such a fascinating and inspiring instrument. You can get a million and more of sounds out of it.
I love how the filter of Lossy changes the overall mood of the sounds.

Deep Analog Ambient Drone – Moog Mavis Soundscape (19 Minutes)

video upload by The Pedalboard Orchestra

"This calm and meditative ambient track is my first use of the Moog Mavis semimodular analog synthesizer.

This video is intended for deep listening and quiet immersion.
🎧 Headphones recommended for the full spatial experience.

The Mavis VCO plays itself as a drone, modified via the Mavis patch bay with LFO and Sample & Hold. Further modulation is provided by the Recovery Effects XCV pedal.
The Dark Star Pad Reverb from Old Blood Noise Endeavors calms it down even more,
before the sound is mangled by Hologram Electronics Microcosm in various stereo settings of the Warp algorithm.
The whole thing is pushed out in space by the Source Audio Ventris Dual Reverb, using the E-Dome and Offspring algorithm in parallel.
Patch cables: myVolts Halo.

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.

This project is an exciting step toward preserving and reimagining classic digital synthesizers in modern workflows. If you’re into vintage gear, wavetable synthesis, or rare digital textures, this is definitely worth exploring.

"This is a unique opportunity to buy a monster synth, that is also a piece of synth pop history. Two cabinets plus the original keyboard, all lids, interconnection cables and original manual included. The first cabinet is a Roland System-700 Lab is one of the rarest and most sought-after modular synthesizers ever built.
Introduced in 1976 as part of Roland’s legendary System-700 series, the Lab version was designed as a compact, self-contained modular laboratory for advanced sound design, research, and education — but with the same discrete analog circuitry, massive sound, and build quality as the full studio system.

This one was owned by Bill Vorn, keyboardist of the synth-pop band Rational Youth, used in the following albums dated 1981 to 1983 : Rational Youth, Saturdays in Silesia, City of Night and I want to see the light, as reported in the certification signed by Bill Vorn himself, provided in the item. The second one is another original SYS 700 one, connected and internally cabled to the main one by means of the original cable, with the super rare modules that you see in the picture: an additional, multimode filter, the great output module and… a professionally custom module with a perfect ARP 2600 VCF clone… plus other stuff.

All the best Sys 700 modules, featuring the iconic vintage Roland tone — warm and incredibly dynamic — and offers an extraordinary range of sonic possibilities thanks to its flexible patch architecture. Perfect for collectors, professional studios, or synth enthusiasts looking for a centerpiece instrument with historical and musical significance. The system sports a comprehensive modular architecture with 3 oscillators, 2 filters, 2 VCAs, 6 envelopes (!), mixer, phaser, spring reverb (HUGE) and …utilities.

Legendary System-700 sound — powerful basses, evolving textures, experimental tones. What to say more? Fully functional and in very good cosmetic condition with minor signs of use. You will never find another in such condition. Last call…"

Exploration Situation

video upload by Memetune Studio

"Here I have set up an exploration situation, whereby I can mess about with various settings on the Buchla 200 while it's playing a semi-random patch

I'm using the 208 Easel module for initial sound generation, which goes to the 296 Spectral Processor, then out to two places: the even output goes to a mixer input, and the odd out goes to the 288 Time Domain Processor, then into mixer input 2. This goes out to the 289 Defect Processor top section, which has Maxlord's Lexi-like (224) reverb EPROM fitted. It's a great reverb! And you can CV various parameters. Joy!"

Strumming on ATRIUM: Keyboarder wants to be Guitarist #whimsicalraps

video upload by Pete Midi

"Whimsical Raps Atrium implements a very special way to play a synthesizer. In combination with the special sound engine it's fun to discover a new world behind the classical synthesizer universe. In this jam I explore the possibilities of the strum touch plate and the chord/scale settings with a distorted guitar like sound. Note that no dedicated guitar effects like overdrive or distortion were used, just a reverb (Eventide Blackhole) and a standard delay (Ableton). The backing track I made with the IK Multimedia Modo Bass and Drum plugins."

Testing 9 Experimental Pedal Combinations – Ambient, Loops & Sound Design

video upload by A Last Picture From Voyager

"In this video, I test 9 experimental guitar pedal combinations for ambient loops, textures, and sound design.
If you feel stuck using the same pedals in the same way, experimenting with new pedal chains can unlock fresh ideas.
Even without the same pedals, this walkthrough can help you imagine new ways to use your own gear for ambient and experimental music.

Let me know in the comments if any of these combinations sparked new ideas for you.

Korg Volca performance Yarnbay Quartet

video upload by Veli-Matti Rautio

"Today Volca session with four Volcas. There were Bass, Beats, FM2 and Modular. Bass 16 steps self-made sequence, Beats also 16 steps self-made drum pattern and Modular 96 steps self-made sequence. FM2 lead playing with sound called Yarnbay with chorus and reverb. Korg microKONTROL midi keys to FM2. Roland Go: Mixer Pro analog mixing desk and Sony FDR-AX43A video camera. Composed, played, arranged and improvised by me in Studio Tupos upstairs livinroom's glass table 23.3.2026.Nr. 1539.

Sessio alkoi Volca Modularilla, tein siihen ensin kuusi 16 stepin sekvenssiä ja yhdistin ne. Sitten mukaan tuli Volca Bass, siihen tein simppelin 16 steppisen bassosekvenssin ja kolmantena tuli Beats, johon tein 16 steppisen rumpukuvion. Ajattelin ensin soittaa soolon Bassilla, mutta päätin ottaa mukaan neljänneksi FM2:n, se hoiteli soolon. Soolosoundina Yarnbay choruksen ja reverbin kera. Volca kvartetti oli kasassa ja eikun tekemään videota : ) Midikiippariksi FM2:lle otin Korg microKONTROL-kiipparin. Mukana myös Roland Go: Mixer Pro ja Sony FDR-AX43A. Yläkerran olkkarin lasipöydällä tämäkin esitys valmistui."

Foltek Mescaline and POM 400 Part 2: Will it Techno?

video upload by Infin-D

"The patch here is basically the same as the last video, but I increased the tempo on the Mescaline trigger sequencer, tightened up the envelopes on the POM 400, and routed some modulation from the POM sample & hold to the Mescaline percussion voices. The sawtooth oscillator on the POM once again provides a dissonant, chirpy counterpoint.

All audio from the Mescaline is routed through the POM, gets some compression and reverb from the Zoom MS70 cdr+, and delay from the Korg NTS-1.

Recorded live on the Zoom L6, audio normalized in Audacity."

Foltek Mescaline and POM 400: Melodic Modular Magic

video upload by Infin-D

"The Folktek Mescaline lives up to its name, it reliably takes me to magical, trippy places. It's biggest weakness is the 'Channel' module, which generates rich polyphonic tones, but lacks envelope control, so basically it's a melodic drone. Enter the Teenage Engineering POM 400, with its dual envelope generators and VCA's. Now I can route the Mescaline voices through it, and triggered by its sequencer clock I can get nice snappy, plucky melodies- modular magic.

The Mescaline melodies and percussion are accompanied by the POM saw wave oscillator, outgoing audio gets some compression and reverb from the Zoom MS70 cdr+, and delay from the Korg NTS-1.

Recorded live on the Zoom L6, audio normalized in Audacity.

Probability-based Transposing with PRECISION VOLTAGES, CHANCE DELAY & a Step Sequencer #eurorack

video upload by AJH Synth Official

"A sequencer patch using PRECISION VOLTAGES and CHANCE DELAY modules for probability-based transposing of steps. Also featuring sound from a single VCO and the SONIC XV filter & wave folder.

Video & Performance by @DreamsOfWires

PATCH BREAKDOWN:
A Doepfer Mini Sequencer is playing a simple 5-step sequence. The clock is from the DUAL LFO + VCA module, which is also triggering an DH-ADSR envelope generator (connected to audio VCA), and the SAMPLE HOLD & SLEW module.

Because the sequencer gates aren't being used to trigger the envelope generator, I can use them elsewhere, and on the Mini Sequencer they can be turned off per step, so instead I am sending these gates to the PRECISION VOLTAGES (Gate A). This means that whenever a gate signal is received, Precision Voltages will activate, shifting the pitch of connected VCOs by the selected amount.

To add variety to this, I am first running the gates through the CHANCE DELAY, with which I can adjust the chance/probability of the gates being passed through to the Precision Voltages, or ignored. This means that the transposed notes will only randomly occur, based on the position of the 'Chance' pot, here at 50%.

Precision Voltages is dual channel (A & B), but I'm using the combined A + B output, so that any semitone or octave changes that I make to channel B will be combined with those on channel A, which is the only channel being switched on or off by the incoming gates. This means I can transpose the whole sequence by the same selected semitone and octave values (here plus or minus 5 semitones) and still have the selected sequencer notes randomly transposing by the same interval.

As for the sound - just a single triangle wave into the SONIC XV Diode Ladder Filter, manually adding the wave folder to create a much more interesting timbre, and with the clocked SAMPLE HOLD & SLEW module randomly modulating the filter frequency, via the DUAL LFO\s built-in VCA, which is slowly modulating the level of the Sample and Hold from strong to nothing.

Mixed on a @solidstatelogic BigSix with @vermonagear DSR-3 Dual/Stereo (real) Spring Reverb. Both cases powered by the Konstant Lab StrongPWR, with small case using a Polyend Anywhere USB PSU, powered by the USB output of the StrongPWR. Clear acrylic Eurorack case by CASA Modular, Japan."
