Bubblesound SpringVerb Demos

video upload by bubblesoundmodular

"The TR606 kick is going into the bubblesound Booster and then into the SpringVerb. The noise is thanks to a very old Mackie 1604. Starts in Low Pass, then Band and finishes in High Pass. more of a test than a demo"


"Another test of the SpringVerb. This has the VCOb going into the 141 and then the SpringVerb. simple 2 note sequence. starts in Low Pass, then Band and into High Pass. actual demos coming, this is just a test."

Hilda Now Available

Trailer video previously posted here.

"The best of both coasts...

Hilda is a Complex Oscillator Synth, inspired by the most interesting aspects of both west-coast and east-coast synthesis techniques. You’ll find a wave folder, lowpass gate, and audio-rate modulations, but also a 12-mode filter and traditional VCA circuit.

All parts of the instrument are carefully circuit-modelled to sound as analog (or digital, where applicable) as possible. It’s laid out like semi modular synth, but without the patch cables and all the interesting connections are already normalised for you.

The eclectic mix of different synthesis components adds up to a unique sounding electronic instrument, which can be used as a playable synthesizer, a drone/noise box, a MIDI sequencer and an audio effect for external audio – or any combination of those three." Appstore link | Manual

Introducing the Pianophonic wavetable and sample module from Knobula

video upload by knobula

"Pianophonic is an 8 voice polyphonic wavetable synthesiser that takes its inspiration from the piano’s string and hammer mechanism mixed with a bit of 90s digital keyboard charm..

Featuring 3 wavetable oscillators and a single sample playback engine per voice, Pianophonic generates rich and complex evolving sounds as well as extraordinary hard hitting piano-like sounds. With simple direct controls for all the parameters that matter, no confusing menus and all squeezed into 12hp of concentrated eurorack module. Featuring midi to Gate Out, Gate In, V/Oct, Chord Select and Wavetable morph CV inputs. Its a fully featured versatile polyphonic oscillator module that can sit at the core of your eurorack system."

RLSD // 100% Syntakt // Offbeat Hypnotic Techno

video upload by Dave Mech

"I released a course for Syntakt! Get here:

When I sit down with Syntakt most often these hypnotic trips flow out. Syntakt is capable of great textures. Today is freedom day in The Netherlands hence the name of this jam (released). There's an obvious dissonance between this celebration and what goes on elsewhere in the world.

This groove was completely made with Syntakt. Post processing: a slight mid EQ dip, compression, subtle OTO boum comp+saturation."

Morphor Ensemble - Analogue 8 Voice BBD Chorus

video upload by Morphor

"A small preview of our new module, the Ensemble - Analogue 8 Voice BBD Chorus. More to come!"

"The Morphor Ensemble is an 8-voice fully analog chorus effect module. The module can truly upgrade any input audio into a sound with body. Transform your creations into warm and full sounds as if a whole orchestra is playing them.

Morphor Ensemble features extensive control over your effect with number of voices selection, CV-able spread, two full-featured LFOs and control over the amount of dry-add signal. This way it is possible to create a wide range of effects, from subtle broadening or humanisation of your sound up to pitch-bending craziness.

The module features a true analog audio path based on eight BBD devices, known for their authentic and warm timbre. In summary, the Morphor Ensemble is a high-end, flexible chorus module for every analog lover."

Boring Systematic Testing of Simmons SDS7 drum synth modules / insomnia cure

video upload by tonetweakers

"When you deal in vintage synths, attention to detail is essential, because every physical control or electronic component has the potential to be problematic. So we test our gear multiple times systematically over an extended period (with a long burn in test) to make sure we don’t overlook anything. Many of our so called competitors dont, which is why we have many loyal customers. In this video, we are systematically testing the last of 8 Simmons SDS7 modules. Its a boring but necessary process. Anyone familiar with sds7 editing knows that one push of the wrong button and the sound you were editing is erased and you’ve gotta start over. This only happened once while testing this set of modules. 😂

Thanks for watching!

"Berlin-based composer, singer, pianist and vintage and modular synth devotee Lisa Morgenstern first came to significant public attention with the release of Chameleon in 2019. Her compelling live performances led to concerts across Europe with artists including Ólafur Arnalds, Joep Beving and Max Cooper, as well as at festivals and prestigious venues, from Iceland Airwaves to the Reeperbahn Festival at the Elbphilharmonie Hamburg.

Most recently she was hired to co-compose the score to one of Netflix's priority drama series of 2022, The Empress, and additional studio collaborations with artists such as Casper, Balmorhea and Aukai. Live shows with the renowned Bulgarian Voices Berlin choir and, separately, the Munich Radio Orchestra meanwhile won further acclaim, with both institutions subsequently crucial to Morgenstern's upcoming album, for which she also wrote the complex arrangements.

Super 6 - LFO 1 (Part 2)

video upload by UDO Audio

Part 1 here. Additional posts here.

"Hazel’s back with the part 2 breakdown of LFO 1’s features, this time delving into using the LFO as an additional oscillator.

Using the rotary selector on LFO 1, you have the option of two high frequency modes HF and HF TRK. These modes can be placed onto DDS 1 or DDS 2 by using the toggle switch within the LFO 1 section. Within HF mode, LFO 1 can be set to a frequency which can be creatively used as a drone or as a constant modulation source.

Enable HF TRK mode and LFO 1 will be set to a high frequency which responds to key tracking at the same time, behaving as a third oscillator! While you can move the LFO 1 rate fader to set the core frequency, it will now respond to the chords or notes you play maintaining the same interval in pitch, giving you scope for really interesting and rich sounds, as so expertly demonstrated by Hazel in the video above.

Expressive E Osmose - First 10 minutes going through patches

video upload by NGC0 Music

"Finally got my hands in one of these, bought used from a fellow synth-head in Italy. You will hear me going through some factory presets, with some Microcosm and Nightsky for FX, although it gets a bit too messy at some point, you can have an idea of how nice it is.

I had to reduce the bend interval from 1 semi-tone to 1/2 semi-tone, otherwise it sounds more like a player making too many mistakes, rather than adding expressivity."

Softube Model 80 - Sound Bank '79

video upload by Polydata

"Drawing from the earliest days of polyphonic synthesizers, Sound Bank ‘79 for Softube Model 80 finds its inspiration in synthesizer music found in documentaries and library music from the late 70’s and early 80’s.

A bank comprising 30 patches for instant inspiration. The goal was to squeeze as much vintage analog juice out of this plug-in as possible, primarily working within the constraints of the original Sequential Circuits Prophet-5. Part of the magic of the Prophet-5 design was it's clear workflow, enabling you to get a wide array of sounds quickly. I'm happy to say that Softube have stayed faithful to this simplicity that has helped this instrument to endure all these years.

Sound Bank '79 is a series of vintage tones for different synths and plug-ins, so look out for future releases. Recorded completely dry with no external effects or processing.

Generative Drum Machine sneak preview

video upload by

"So I was trying to check if I could port BRAIDS to the PI PICO. It took me near 3 months of studing and tweaking and adapt the code and finally I got it running

PICO is like 6 times more capable than the original stm32f103 of braids so it left me with a ton of power to experiement and tweak. The first logical step was to replace the 7 segments screen with a 128x64 pixels OLED screen.

Then I added a generative sequencer. And a second envelope. And an LFO. BOOM, it starts to look like a generative drum machine. I fucking love generative drum machines and most of my projects ends looking like one, but they all came from a totally different perspective, sounds totally different and has a unique archhitecture tailored to that system

Currently this one has parameter locks, per step saving and I will be adding probability probabily too :D

Another branch of the project would be to add MIDI (currently working on it) and turn it into a polysynth. Kind of Microfreak, but with the braids oscillators. But that one if ever, will be quite in the future yet.

The Drum machine, is near ready to lauch, and maybe ready to appear as build units, kits and PCBs in my Tindie and Etsy stores, as always"
