"Up for sale is an original 1974 EMS Synthi 100 Synthesizer. I am the second owner of this amazing instrument. It is in incredible condition for an item of its age and size. Very few of these were produced in the early 1970s and most of them were sold to institutions, private studios and musicians - these almost never turn up for sale on the open market.

This particular Synthi 100 was one of the last produced by EMS (London) and has all of the standard factory updates including newer scope, sequencer memory display and patchable multimeter. below is a list of what is included with the auction:

Tech Talk: Vera Grace - How Modular Gear Shapes Her Hypnotic Techno Sound (Electronic Beats TV)

video upload by Telekom Electronic Beats TV

"For this Electronic Beats Tech Talk, we visited Dutch DJ and producer Vera Grace at her home in Amsterdam. With a background from the Conservatorium van Amsterdam, she has developed a distinct techno identity rooted in experimental sound design, modular exploration, and hypnotic rhythms that bend your sense of time. Her dive into modular synthesis reshaped her creative process, leading to a fully live analog setup she now brings to the stage. Shifting fluidly between broken beats, ambient explorations, psychedelic textures, and driving 4/4 energy, Vera continues to push her sound forward while staying connected to techno’s foundations."

The Fancyyyyy K-Accumulator - A Complex Oscillator Made of Complex Oscillators 👽

K-ACCUMULATOR - 21st Century Complex Oscillator video upload by Fancyyyyy Synthesis

Note, this appears to be the first Fancyyyyy post on the site. :)

Currently exclusive to Perfect Circuit

"The Fancyyyyy K-Accumulator is a revolutionary stereo complex oscillator that combines cutting-edge synthesis techniques in an intuitive, hands-on architecture inspired by classic complex oscillators. Designed in collaboration with Grrrwaaa aka Graham Wakefield, creator of Max/MSP's gen~ platform, fans of experimental timbres and novel synthesis techniques are right to celebrate K-Accumulator's emergence into the Eurorack landscape. Seamlessly combining pulsar synthesis, phase modulation, and complex 3D waveshaping, K-Accumulator pairs its modulation and carrier oscillator pairs with an onboard function generator, pattern generator, and flexible root frequency quantization and manipulation, providing fruitful terrain for exploring captivating timbres in systems of any size.

Starting from a core sine and cosine wave, K-Accumulator provides an innovative morphing matrix architecture which progressively remaps panel controls to waveshaping positions for the carrier and modulator oscillator section. Expand tones with complex harmonic wavefolding, blended frequency shifting, and harmonic stretching. Shape tones into newly mangled forms with formant synthesis, sync damping, and asymmetric phase modulation, or invite chaotic movement and surprise with damped cross phase modulation and damped self-feedback. Even the onboard function generator can sing, enabling audio rates for pulsar synthesis that can be operated independently from the main oscillator. Despite the PhD in DSP you might need to fully understand K-Accumulator's synthesis engine, the morphing matrix architecture allows these many manipulations to be smoothly and seamlessly explored through intuitive manual control.

Even further possibilities abound when employing K-Accumulators twenty-three patchable points of external signal integration, with most primary CV inputs featuring dedicated attenuverters for precision control. In addition to CV control over the frequency, shift, depth, morph, and shape controls, the primary oscillator in K-Accumulator offers CV inputs for thru-zero phase modulation, damped/pulsar control, and an external input which can be used as an external sync source or for pitch-tracking an external source to use K-Accumulator to harmonize with external sources. Its outputs offer both the sine and cosine waves, creating unique stereo space through the phase differences on each output as it is manipulated by the waveshaping engine. Control root frequency for the oscillator section, function generator, or both, with both 12-TET and Just Intonated quantization, multiple scales of frequency control, and a dedicated detune control in the modulation oscillator for inharmonic applications.

At the left side of K-Accumulator, a highly flexible function generator is onboard for additional modulation or audio sources. Multiple unique internal trigger modes, looping capability for LFO and audio rate oscillation, thru-zero FM, and onboard waveshaping make this a potent source of signal manipulation for either K-Accumulator itself or anywhere in your system. To the right of the function generator, a Delta-Sigma pattern generator enables stepped and smooth pseudo-random pattern modulation, providing an onboard sequencer for root frequency, or any other parameter. With its immensely capable and unique synthesis engine alongside flexible and creative onboard modulation sources, Fancyyyy's K-Accumulator offers a new vision of complex oscillation for contemporary modular synthesis, translating vanguard digital signal processing into a familiar form factor for deep sonic exploration, intuitive skronking, and new musical forms yet unheard."

Soundbank for the Dreadbox Artemis - Carlo Mezzanotte

video upload by carlomezz

"(testo italiano in basso)
A bank of patches for the Dreadbox Artemis, a lovely-sounding, 6-voice analog polysynth from Athens, Greece. With dual filters (LP + HP), two VCOs + sub, thru-zero FM, audio-rate filter modulation, mod matrix, and a four-stage effect section, it offers a great palette of possibilities for the dedicated programmer. In the video, I kept my focus on 'playable' sounds, even though many of the patches lend themselves to be sequenced as well.

Un banco di suoni per il Dreadbox Artemis, uno splendido synth analogico con polifonia a 6 voci realizzato ad Atene, in Grecia. Con doppio filtro (LP + HP), due VCO + sub, thru-zero FM, modulazione in gamma audio del filtro, matrice di modulazione, e una sezione di effetti a 4 stadi, offre una vasta tavolozza di possibilità per il programmatore. Nel video, ho tenuto il focus sulla 'suonabilità' - anche se molti dei patches si prestano anche ad essere sequenziati."

Ocean Swift releases Tyrian Tine - Free Unstable Chime Engine for Kontakt Player

video uploads by Ocean Swift / Faxi Nadu

"Ocean Swift announces the release of Tyrian Tine - a FREE compact, yet potent Kontakt NKS instrument for generating unique, randomized bell and chime tones. Its asymmetric dual-layer engine pairs a wavetable oscillator - with purposeful instability, morphing, and controlled randomization - with a sample oscillator curated from bells, kalimbas, music boxes, and other metallic oddities. The result ranges from crystalline fantasy tintinnabulation to gritty, bronze-like strikes and haloed sci-fi swells.

Tyrian Tine lives where chapel glass meets starship hulls. Play a note and bells bloom like constellations; strikes flare, then drift into haloed swells that hang in the air like omens. It feels less like triggering samples and more like waking a signal - intimate one moment, cathedral-wide the next, always poised on the edge of a story. Tyrian Tine doesn’t just make bells - it sketches scenes: ruined kingdoms, cold moons, quiet victories."

Free Omnichord Style Plugin - GCS Strum Plate - An Intuitive Strum Plugin

video upload by Gulf Coast Synthesis

"We developed a new plugin that allows users to intuitively strum notes on software instruments. Instead of using the typical autochord style of an Omnichord and other products, you can hold a chord on a midi keyboard and intuitively strum across the gold plate or via the pitch wheel.

Download it now for free at www.gulfcoastsynthesis.com.

Works on all DAWs and operating systems via AAX, AU, VST, and Standalone formats."

Separate Notes from Rhythm

Strum Plate is a MIDI Effect that decouples what you play from when you play it. Inspired by the touchplate interface of the classic Omnichord, it allows you to hold a chord with one hand and "strum" the notes into existence using your mouse or pitch wheel.

Djupviks Gats // Grainy Reverb // Angry Filter

video upload by Lesjamusic

"‪@vikingsade‬ Djupviks Gats is a grainy reverb feeding into a wasp-style bandpass filter, with sample-and-hold modulation built into the signal path. By default, it samples your incoming audio to modulate the filter cutoff - creating stepped, glitchy textures that respond to your playing dynamics. The offset control lets you shape that response from aggressive ducking through to keeping the filter permanently cracked open.

In this video I walk through the module and show a couple of patches demonstrating what it can do.

Features:

Grainy reverb into wasp-style bandpass filter
Internal sample-and-hold with adjustable clock
S&H can sample audio or external sources
Bipolar offset control for shaping filter response
Pre/post feedback switch
External clock sync"

tech notes:
this is a one take live recording. with mixing and mastering done in post.

all audio recording are multi-tracked (4 stereo channel) via usb c from S-4 to my hackintosh (macos sequoia). recorded using ableton live 11.

i set the buffer size to 256, which seems to be a sweet spot. i was using buffer size 128, but i was getting a lot of noise crackles/cpu drop out.

ableton is sending midi clock to S-4 via usb, then from S-4 i send midi clock to Plinky via TRS 3.5mm. i was sending midi clock to Plinky from ableton via usb, but it was not stable/very wonky. then i tried the TRS from S-4 which was very tight and a lot better.
and also , i need the set the midi sync delay in ableton, i think its about -36ms.

audio out from Plinky goes to S-4 analog in, and i put it into track 4."
