Everything Oscillates: A closer look at the Serge Random Source Helios & Paris Flash

video upload by Bleeps and Boops

"Following up on Part 1 - • From DIY to Cult Legend: The Serge Synthes... [posted here] - here's a closer look at two of the R*S Serge 50th Anniversary Paperface panels. If you've not seen the first part yet, please do since it gives a decent background on where these came from. Any corrections or questions, please comment below: I've tried my best but there's always going to be an omission or mistake.

All the background music was made on the Serge - if I get the chance I'll upload it somewhere. It's genuinely the most productive six weeks I've ever had with one synth.

These new versions are a re-work in collaboration with Serge himself, to update and improve his original Paperface circuits. As such the oscillators track nicely over the full range, everything is stable, and overall it's better suited to life in a modern studio.

As before, an enormous thanks to ‪@serge-modular‬ for the loan of this beast.

Time to start saving I think...

As ever, thanks for watching!"

Ear Modular Introduces 暮秋 The End of Fall

video uploads by Ear Modular



"The End Of Fall is a feedback-filled effects unit in a 40hp Eurorack format.

By adding two expansion boards and replacing the front panel, it can be reconfigured as a standalone device.

The core of The End Of Fall consists of two ladder filters and two echo effects. The signal chain routes Filter A to Echo 1 and Filter B to Echo 2, with their outputs mixed together for the final output. Each filter features a CV control input for cutoff frequency, while each echo has a CV control input for delay time.

At first glance, this may seem like a basic setup, but The End Of Fall offers much more. It is filled with various feedback pathways:
​
1. Internal feedback within each filter, from output back to input, creates a resonator capable of self-oscillation.
​
2. The internal feedback within each echo is essential for creating the echo effect; excessive feedback results in endlessly decaying echoes.
​
3. The output of Filter A is fed back into the input of Filter B, and vice versa. This design was inspired by experiments during the creation of Solar Card Type VII, where it produced unexpectedly complex and intriguing sounds on the card. This concept has been adapted for The End Of Fall.
​
4. The output of Echo 1 is fed back into the inputs of both Filter A and Filter B, and similarly, the output of Echo 2 is fed back into the inputs of both filters. These two global feedback loops transform The End Of Fall into a circular structure without a clear front or back end, allowing sounds to intertwine within this loop.
​
Additional design features:
​
1. Each filter and each echo has its own dedicated input. When feedback is not utilized, the feedback pathways serve as internal bridges, enabling various signal routing configurations such as echo to filter, filter to echo, echo to echo (for multi-tap delays), or filter to filter (for multi-stage filtering). With expansions, outputs can be taken from the end of any effect, allowing the unit to be used as a stereo effects processor.
​
2. The End Of Fall includes a noise source with two functions: it supplies audio to the inputs of both filters, and it serves as an oscillation source for generating internal CV signals.
​
The unit features four internal CV sources, each assigned to one of the four effects. When no external CV is present, these internal CVs provide randomly varying control voltages. If an external CV is connected, the corresponding internal CV is disconnected. These four internal CV signals are generated by sample-and-hold circuits sampling the noise source. Four knobs in the upper-right corner independently control the sample intervals of these circuits, introducing chaotic and unpredictable modulation. A CLK input can interfere with these four sample-and-hold circuits, partially synchronizing them while maintaining an underlying chaos.

There is a slight background noise from The End Of Fall when there is no output, but it does not affect normal use.​​​​​​​​​​"

Valhalla's New FutureVerb

Demo video upload by Stazma

"The lovely folks at Valhalla DSP have released a new plugin called FutureVerb.
As you know I'm a big fan and I had the honor to also be part of the beta testing crew for that one and here is a bunch of test with it (with synths and breakbeats mostly).

Oh and here are some presets I've made during the demos (those tested with Seashell).
https://bit.ly/ftvrbprst

Have fun!!!"

00:00 Intro
02:15 A bit of history about 'pre-delay'
06:57 FutureVerb walk through w/ Tiptop 200t System
18:10 Bonus Supermassive 'Sirius' test
20:14 Breakbeat Torture
23:12 Playing with some preset I've made w/ Instruo Seashell

"The future belongs to those who believe in the beauty of their dreams.

We are excited to introduce our brand new reverb/echo plugin: Valhalla FutureVerb™!

FutureVerb was designed from the ground up to give you the most transparent and realistic reverbs we’ve ever made. 8 years of research and development have gone into creating new and innovative algorithmic reverb topologies. The FutureVerb reverb modes are as close to perfect as we have ever heard.

And, since we don’t actually believe in perfection, we added a colorful and powerful Echo section that can add color and warmth, or keep things as clean as you wanna be.

With 8 original Reverb modes and 12 flexible Echo modes, FutureVerb gives you the sonic power you need to create your own future."

Acid Dub using the Knobula Echo Cinematic

video upload by knobula

"A 5 minute journey into the world of live modular synthesizers, featuring the essential Echo Cinematic module which bases its design on the dub reggae trick of connecting a tape echo into the mixing desk, passing it through the EQ and then sending it back onto itself. Its the perfect feedback loop that teeters on the brink of instability and chaos but rewards with rhythmic beats dripping with trance-like textures."

Error Instruments Introduces Das Ritual Candle Flame Synth Noise Generator

video upload by errorinstruments paul tas



"✨ The Ritual — Let the Flame Speak ✨ The Ritual is not just an instrument. It is a presence — a small, mysterious machine that invites sound, light, and spirit to merge into one living moment. At its core, The Ritual offers two elemental voices: a warm, crackling texture like burning wood, and a deep, sub-harmonic bass that vibrates through the body. Two outputs, two energies, both ready to shape the atmosphere of your space. But the true magic lies in the heart of the machine. In the center burns a candle. Three light-sensitive sensors observe the living flame — every flicker, every breath of air, every tiny movement of light. The flame becomes the conductor, shaping rhythm, modulation, and tone. It decides the pulse. It guides the sound. It becomes an oracle of vibration. With control voltage input, three intuitive potentiometers, and full compatibility with stand-alone setups, pedal chains, and Eurorack systems, The Ritual integrates effortlessly into any sonic temple you create. Add a touch of delay, let the harmonics bloom, and suddenly the sound becomes something else — psychedelic, hypnotic, deeply alive. A soundscape where chaos becomes beauty, and the smallest movement of fire transforms the entire universe of tone. Hand-crafted by Error Instruments, built in rugged Bricky format, The Ritual invites you to surrender your control and let the flame speak. Light the candle. Start The Ritual. Let the fire shape your sound"

Absynth 6 by Native Instruments - No talking demo

video upload by ADL-MusicLab

"Hi, everyone!

Here's to you my 'No talking demo' of the stunning Absynth 6 by Native Instruments.

Absynth 6 marks the return of a legendary semi-modular synthesizer. Built for textures that transform and breathe, it invites you to shape sounds that are entirely your own. Deep enough for complex sound design, and intuitive enough for newcomers, it opens up distinctive, living sounds for cinematic cues, ambient soundscapes, and electronic productions.

Absynth has a long, storied history of surreal sound. The strange textures and dreamlike tones return with Absynth 6, the latest in this prestigious line of semi-modular synths.

This version keeps the heart of the hybrid engine you know. It combines subtractive, FM, wavetable, and granular synthesis into one flow that makes unusual sounds feel natural to create. A refreshed interface, a new waveform editor, and an intuitive visual browser make it easier than ever to craft otherworldly soundscapes.

The launch of Absynth 6 is the story of rebirth. It honors the strange beauty that defined the original, while bringing it into a new era with a new suite of tools and accessibility features.

Truly a sound-designer's dream, opening up endless creative possibilities!"
