Defect Processor Buchla 289

video upload by Memetune Studio

"A few months ago I managed to snag a Defect Processor Model 289 made by Alex Pleninger (Keen Association) and Roman F

This hyper-rare module adds some appropriately bonkers digital FX to the Buchla 200 series system, by using two independent stereo digital effects units based around the rather interesting Spin Chip platform (it has two of them inside)

The module takes any audio signal and subjects it to various Spin Chip algorithms - there are 8 per section, and they are pre-set on EPROMS on the board behind the panel. The good news is you can swap out the EPROMS and change the 16 algorithms if you so desire, and you can even create your own if you get the Spin Chip programmer

I have a set that includes this insane delay patch. The module has CV inputs for some of the parameters (not many Spin-based products have this facility AFAIK) but here I am playing around with the delay times and feedback levels by hand

I’m also tweaking the 259 timbre, the LPG decay time, and the mix between Noise and VCO, and the Bandpass filter

Crazy sounds and defects abound!"

The unique sonic character of the Korg Polysix is explored, revealing how its classic warmth and modulation capabilities contributed to the iconic Italo Disco sound.

One of my favorite italo disco tracks from the early 80s.

EF118 Vulcan's Hammer

video upload by electrofaustus

"This device is an accelerometer-controlled oscillator. It works by reading the position along a 180-degree x-axis and translating to a frequency. In the fully back position, the oscillator is at its lowest note – roughly 100hz (or D3 on the musical scale). As you rotate the hammer forward, pitch increases. In this position, the frequency is roughly 2000hz (or B6 on the musical scale). That’s about a 4-octave range. The controls are straightforward: A red push button on/off switch and a knob to control volume. The ¼ inch audio output jack is located at the bottom of the handle. It’s powered by 3 AAA batteries located inside the enclosure that come included in the unit when purchased. They can be easily replaced by unscrewing the base. Vulcan’s Hammer goes on sale today and retails for $200"

Check with dealers on the right for availability.

"Like the Roman God Vulcan, what if you could generate immortal oscillations from a mighty hammer? Ponder no more. Vulcan’s Hammer by Electro-Faustus allows you to call to the Gods by simply rotating the device along a 180 degree field. Note range is roughly 100Hz (D3) to 2000Hz (B6). That’s almost 4 octaves! Powered by 3 AAA batteries.

*Like all of our devices, the Vulcan’s Hammer is noisy and glitchy by design. Have fun with it!"

BAF 2025: Black Corporation Expander MK2

video upload by sonicstate

"At NAMM 2025, we caught up with Roman from Black Corporation who walked us through their latest innovations. First up was the Monolith*, a signal generator not created by *Black Corporation*, but developed by *Black Corporation team members. Roman explained that the Monolith allows you to generate presets, LFOs, arpeggiators, and MIDI CC. This versatile device outputs via USB host, TRS MIDI, or USB-C to computer, providing an easy way to enhance your hardware synths with additional oscillators, LFOs, and envelopes.

Then we got a look at the *Expander MK2*, which represents Roman's dream multi-effect processor. Featuring classic delay models including the Lexicon PCM42 and a BBD delay, the Expander MK2 incorporates two types of reverbs - including one developed in collaboration with Maris - as well as a spring reverb with digital pre-delay and a Tilt EQ. With a rich array of modulation options, including a ring modulator and OTA-based phasers, the Expander MK2 is a comprehensive solution for integrating multiple effects. It boasts extensive connectivity options and total recall via MIDI CC. The Expander MK2 is set to ship at the end of spring 2025 at a starting price of $5,000, with pre-orders available for this reduced price before an anticipated increase."

New ULT-SOUND DS-4M Drum Synth Demos

video upload by Korablove Roman

Available at Nightlife Electronics

You can find additional demos in previous posts here.



"The DS-4 drum synth, which was released by Toyo Gakki in the 1980s under the "ULT--SOUND" brand and was used by the drummers of Japan's leading techno-pop group, has been revived in modern times. An inspiration for many modern drum machines, the DS-4 is heavily sought after for it's immediacy and ease of programming. As a 45 year old drum synthesizer, finding an original for a reasonable price without needing a complete restoration is not the easiest task. This is why the DS-4M project was brought into existence. Using all original schematics as well as original components, many of which are incredibly rare to find, the DS-4M is meticulously built by hand using thru-hole components. Physically, it is built like a tank to last for decades of enjoyment and creativity. What's more, modern MIDI and CV/GATE inputs have been added along with individual outputs and a high quality, balanced MAIN output ready to take the legacy of the Ultimate Sound DS-4 far into the future. The new functions also add an exciting twist: using the SINE or SQUARE waveforms, DS-4M also works as an up to 4 voice synthesizer, or any combination of drums/percussion with synths with accurate tuning as well"

Korg Wavestate - "Metamorphoses" Soundset (40 Exclusive Performances)

video upload by LFOstore

"The idea behind this soundset is based on an ever-changing soundscapes and transforming presets with their cycles of birth, formation, extinction and possible rebirth. We aimed to create a unique bank of sounds that would reveal the palette of possibilities of our favorite synthesizer, Korg Wavestate. So we produced a captivating product with rich, flowing sound worlds. Here you will find inspiring atmospheres and pads, layered instruments and living sequences!

Many ancient myths tell of transformations. For example, when Apollo is chasing the nymph Daphne, she calls on her river-god father for help and he turns her into a laurel tree to save her. There is a poem «Metamorphoses» by Roman poet Ovid tells of various metamorphoses-transformations: people into animals, plants, constellations, stones, etc. The creation of the world itself is considered a metamorphosis, as is the story of Julius Caesar's transformation into a star.

This soundset with 40 exclusive sample-based performances was carefully crafted by the well-known sound designer, OttO K. Schwarz. The soundset will work with both hardware and software (native) versions of the synthesizer. The proposed sounds will be appropriate for both studio work and live performances. Transform your compositions with this new soundset from LFO Store!

☀ SPECIFICATIONS
This soundset include:
♫ 40 exclusive sample-based presets: 8 ARPs, 3 Atmospheres, 3 Basses, 7 Instruments, 6 Leads, 9 Pads & 4 Sequences. All presets are royalty-free!
♫ The sample bank of 1Gb+ (external samplebank should be stored in the settings).
♫ Instructions are included.
