Explaining and testing the Time Machine & VCA Expander by OAM Modular
video upload by Stazma
"Today we check out the Time Machine by OAM Modular, on it's own and with it's new VCA Expander.
This thing is a very weird and powerfull 8 Tap delay with an agressive feedback path and a VERY wide range of delay time. It can go from ambient style delay / reverb to pure glitch madness (great on drums). Oh and it's stereo and clock syncable."

SEOK - PLUTNIK – Complex Dual VC-LFO [DEMO no talk]
video upload by SEOK synthesizers
"This is a pure modulation party in a small footprint. The Morph and Merge functions provide access to complex waveforms for a wide range of modulation. Distribute them across your rack via nine outputs.
Each LFO offers fast or slow cycling, with selectable square and triangle shapes. The fast cycles reach into audio territory at around 100 Hz, making it useful for percussive modulation and low-end movement. In slow mode, cycles extend up to ~35 seconds. With external negative CV, this can be pushed into the range of around 10 minutes.
Blend the LFO signals, or any external signals (including audio), in the Morph section. Or use the signals in the relational logic section, Merge, which opens up a wide set of derived waveforms by slicing, combining or rectifying. Pseudo waveshaping.
Designed and hand-built in Sweden."

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.

FORMANTA EMS-01 - Ode To Devotion (Live)
video upload by LFOstore
"This composition played live by Nick Klimenko on recently restored & tuned flagship of soviet synthesizers - Formanta EMS-01.
Its very hard to tune OSC sections & there are not so many fully working & tuned units in the world!
Thanks to / @ДмитрийБоровских-ш7п for midifying & tuning work!
Working unit sounding ultra mega magnificent!
FORMANTA EMS-01 is an electronical music instrument combining a polyphonic organ and a monophonic synthesizer. It is designed to perform music of all genres and to create various sound effects while recording soundtracks for movies and plays, or studio recording. The organ has a 5-octave keyboard, 6 preset sound timbres, frequency vibrato with adjustable vibrato delay, decay adjustment and a stereophaser (both for organ and synthesizer). The "vibrato delay" scheme is activated again only after all the previously pressed keys are released. In the "legato" mode the "vibrato delay" scheme is not activated.
The synthesizer has:
3-octave keyboard;
modulator, modulation voltage from which is applied to frequency modulator, width modulator, filter, and amplifier; broad band oscillators 1 and 2 (with various waveforms);
mixer, designed for summation of signals from oscillators 1 and 2, noise generator, external source, and ring modulator; filter, designed for dynamic and static changing of the spectrum of summarized signal from mixer output;
amplifier, designed for making the sound corresponding to various parameters of the envelope;
Visual division of the synthesizer panel into the above listed sections and their lay-out make it more easy to orientate oneself while setting the required timbre. Besides, the synthesizer is able to simultaneously control one more similar synthesizer through a special cable and connectors CONTR IN and CONTR OUT.
The instrument provides the opportunity of connecting stereo headphones; the volume in headphones doesn't change in case of changing the volume of the instrument from zero to maximum at all the outputs of the instrument with the foot pedal; thanks to this, preliminary control of timbre through the headphones before applying it to amplifiers is possible. By switching on PHASER into the channel of organ or synthesizer, it is possible to get stereo sound in the outputs STEREO L and STEREO P. In case PHASER is switched off, both channels will function in MONO mode."
