"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."

"Machinedrum Sample Pack https://akihikomatsumoto.sellfy.store...
The Elektron Machinedrum, first introduced in the early 2000s, was not simply a drum machine. It was a digital architecture built to generate percussion with surgical precision and metallic sharpness. Its synthesis models produced results that went beyond drum programming, moving into the territory of sound design. Even today, no software plugin has managed to fully replicate its distinctive texture.
This collection captures that uniqueness. Every sample was recorded directly from the Machinedrum itself. No external processing, no layering. What you hear is the circuitry of early Elektron design, distilled into one-shots that highlight the instrument’s raw identity."
"Full, deep dive into creating paraphonic microtonal drones on the Korg and Behringer Monopoly paraphonic synthesisers. This creates deep, mesmerising tones and textures. It's a ticket to space.
If you know of other synths that can do this please comment below and I will update this description for everyone.
Getting into Microtonality: One of the easiest ways to enter the microtonal sphere is to learn to make microtonal paraphonic drones. Once you have the basics, there is an infinite number of microtonal texture to explore, either scales or chords. The Monopoly GUI architecture is unique amongst synthesisers for being able to doing this because of its "chord" store function. If you know of any other synths that can do this too, please comment below and I will update this description for everyone.
Inspired by the drones from the Tanpura and Shruti in Indian music and other cultures, which use drones.
WARNING!!! Once hear this, you can never unhear it.

"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…"
Here’s a barely-used Butterfly Benjolin from Macumbista’s new “RM” series of Benjolins: a pair of Rob Hordijk’s oft-copied Benjolin synthesizers in a distinctive cigar box enclosure, made under license and with several improvements by Macumbista Instruments and Frog Leg Synthesis. The most obvious enhancement is the ring modulator now standard in Macumbista’s Benjolin designs, which greatly expands the timbral possibilities. XOR-ing signals can be a nice substitute for RM in a pitch, but it’s great to have the real thing and really dial your sounds in. Patching two ring modulators in series opens up some wild sounds. Within its deceptively simple architecture, you’ll find ample opportunity for sound design, strange loops, and a fair bit of chaos. I’ve just never had the *grá* for R2R/digital shift registers/runglers that so many of my peers have. I gave it a chance, and now I’ll let it go to someone similarly curious, or to one of those obsessives out there. If you’re curious about these, there are loads of videos about the Benjolin on YouTube that will give you a sense of what it can do. There aren’t many videos of the “Butterfly Benjolin V4,” which has the ring modulator and additional enhancements, of which this is a lovely example. Here’s the manual for Macumbista’s new “RM” line of Benjolins: https://macumbista.net/wp-content/uploads/2024/10/Benjo-cheat-sheet-1.2-mid.pdf The Butterfly is two of these in a single enclosure with shared power supply, common 0v, etc. Shipping from Berlin, Germany.

"Kijimi MK2 has landed in the studio and I am enjoying exploring its capabilities, quirks and raw analog sounds. This video is a no talking pretty raw exploration. exploring modulation and creating custom presets. All sounds were created from INIT to give a fresh slate.
Kijimi MK 2 is an 8 voice analog synth inspired by the RSF Polykobal
from Black Corp's website
DEEP 8-VOICE ARCHITECTURE
Each of KIJIMI ’s 8 voices features 2 analog oscillators each with a square sub-bass oscillator, for buttery timbres with extensive sound design options. The sub-oscillator produces an octave lower than the combined VCO1 and VCO2 outputs, meaning you can tune two sub-pitches. Hard sync is available in VCO sync and VCO1-2 and 2-1 configurations for maximum flexibility. There’s also a noise source for adding bite and percussion components. A rich lowpass filter is built around the legendary 2140 chip and the ability to frequency-modulate it via VCO2, creates a full range of sounds from metallic and aggressive to subtle. Both filter cutoff and resonance are available as modulation destinations."
