Modular vid #331

video upload by Phisynth

"Here’s the Max/MSP interface I’ve built to control the awesome Destiny+ Model Q-2. The amount and variety of sounds you can get out of this little device is totally insane. All sounds are coming from the MQ2, with a little delay/reverb from the Eventide Eclipse. The patch is almost done — I still need to build a proper preset management system…

Sequential Showdown: The Surprising Winner...

video upload by Rapid Flow

"In this video, I'm doing a comparison between the Sequential Prophet-6, Prophet-600, and Prophet 10 And the results might surprise you... We're breaking down the raw oscillator tone, the drift and vibe, filter character, best use cases, and that elusive 'vintage soul' to help you figure out which Sequential legend truly belongs in your studio.

If you want exactly these 3 synths in your DAW, get Zensphere! (I sampled them note-by-note). https://www.rapidflow.shop/products/z..."

Comparing the Sequential Fourm to the Pro-One

"I Compared the Sequential Fourm to My Pro-One" video upload by Starsky Carr

5:04 Really Deep Bass - THE FILTER
9:14 They've got Oscillators
11:24 Creating a Few Tones
15:11 PWM and how to match them
19:10 F to the M
20:00 Show Me The Sync
21:19 Pushing the Envelope 24:06 Overall..?

"Some genuine surprises in this head-to-head with the Sequential Fourm and the legendary Sequential Pro-One to find out if the Fourm can give the same vibe.

At first glance, the architecture looks familiar: dual oscillators, classic envelopes, a focused modulation section, and unmistakable Prophet-era DNA from Prophet-5 territory. But the big question is this: does the Fourm capture the raw punch, deep bass, and aggressive character that made the Pro-One a cult classic?

.. and I know it's not a clone :) but in this in-depth demo and comparison, I explore:

Oscillator behaviour, sync, PWM and FM
Filter differences (including low-end depth and resonance extremes)
Envelope response and modulation range
Bass performance, subs, and room-shaking tones
Where the Fourm goes beyond the Pro-One — and where it doesn’t

Rather than obsessing over perfect null tests, this video focuses on feel, playability, and whether the Four inspires the same kinds of sounds and musical ideas as the original Pro-One.

If you’re into analog monosynths, Sequential gear, vintage vs modern comparisons, or you’re wondering whether a contemporary synth can truly stand in for a rising-price classic, this one’s for you.

🎧 Headphones or proper speakers strongly recommended — some of these bass tones go very deep."

He Hates This Synth Because…

video upload by Anthony Marinelli Music

"In this video, I pick one thing I think I hate about 12 classic synthesizers—and then follow that feeling wherever it leads.
We’re talking about legendary instruments:
Minimoog, MS-20, Prophet-5, Jupiter-8, ARP 2600, Moog IIIc ('Plantasia'), Oberheim 4-Voice, Oberheim OB-X, Synclavier III, Elka Synthex, and Yamaha CS-30.
What starts as frustration with a workflow choice, a knob, or a design limitation slowly turns into something else entirely.
Along the way, I realize this video isn’t really about hating synths at all. It’s about relationships.
Every one of these instruments has limitations—and so do we. In any good relationship, not everything is perfect. But when you stop fighting what something isn’t and start understanding what it is, those limitations can become the very thing that leads you somewhere creative and unexpected.
Instead of endless options, boundaries create focus.
Instead of frustration, they create identity.
And in learning to understand these instruments more deeply, I ended up learning something about myself.
This is a video about synthesizers—but it’s also a small morality tale about creativity, acceptance, and finding freedom inside constraints.
Let me know in the comments:
Which synth do you love… even though it drives you crazy? 🎛️"

GERMANIUM FEEDBACK // SND FB-14 MK2 Filterbank // The CRYING GAME // No Talking

video upload by LESINDES

"The SND FB-14 is a stunning GERMANIUM TRANSISTOR based FILTERBANK with 14 fixed Q band pass filters. As you can hear in the demo the sound shaping shaping potential of this filter is enormus.
SND FB-14 is assisted by WLK-Audio Inductive Filterbank (silicon) to control excessive boosts and the core of the wiring: ART passive splitter + mixer SplitMix4. The SplitMix knob marked with the WHITE DOT (blue, unused in this session, is for additional feedback!) is controlling the signal that is fed back into SND.
The basic feed is from TORSO Electronics S-4 sculpting sampler."

Building the ReZyklus - Vangelis' Zyklus MPS1 Clone

This one is in via Jeroen of https://zyklus-mps.com/

"A while ago a group of enthausiasts set out to create a clone of the Zyklus MPS-1 that was made famous by Vangelis for its use on Direct (this was also the inspiration for the actual 'Direct' system he used until ca 1994). The original creators of this machine, Pete Kellock and Bill Marshall graciously allowed us to use the schematics and software to create this clone and have given us their permission to set it free for everyone who wants to make their own. So here goes:

In this GIT repo is everything you need to create your own machine. You will have to source your own parts, but there is a list for that. The parts are basic components, nothing custom, but some items may become slightly rare (like small EPROMs).

Its basically just a Z80 based computer.
There are also files to have the circuit boards and panels created (we used jlcpcb for that), and some 3d printing files for various panel work. A lot of the buttons etc you can get cheaply from Aliexpress and the like. Bin files for the EPROMs are also avialable. I've been also given permission to open source the actual source code, and I will do that too, at some point, but I'm still working on a few small issues before I can do that.

https://github.com/jeroenhn/zykl

There is a discord server you can join where you can chat with other builders.

The clone as we made it, is a dedicated to the memory of Vangelis and it's noted as such on the main circuit board."

See this previous post for a Demo tape on the original Zyklus. See the Zyklus label at the bottom of this post for additional posts including a documentary with Vangelis.

Building a Minimoog Model D From Parts

video upload by synthpro

"Hey Guys,

In this video, I bring you along the adventure of building a really nice Minimoog from parts I have had over the years.

Michael heard this unit on a little Instagram post I made when I first started testing to see if I could get a working unit from the parts and immediately sent me a down payment. It took me about 2 years to source everything needed but Minimoog SN: 5250 now lives a healthy life once more.

Thanks for watching!

Sincerely,
Jareth"

SEOK synthesizers Introduces BOUNCE – One-Shot Event Generator Eurorack Module

video upload by SEOK synthesizers

"Bounce is a compact event generator built for percussive envelopes, bouncing modulations and rhythmic control. It creates trigger-driven one-shots with 8 distinct waveforms that can range from sharp clicks to rounded contours.

Repeat function with a ”bouncing ball” effect, making the bounces naturally fade within the cycle. Length, repeats and delay shape the result from tight hits to rolls, flams and clustered rhythms perfect for kick and bass.

Full CV control + inverted output. Designed and hand-built in Sweden."

05:15 Outro

Additional details:


"BOUNCE One-Shot Event Generator

This is a compact event generator built for percussive envelopes, bouncing modulations and rhythmic control signals.

Bounce creates trigger-driven one-shots with a set of 8 distinct waveforms selectable via the large control knob. From sharp, click-like hits to softer, rounded contours. This offers fast access to clearly different envelope characters.

Repeat function with a ”bouncing ball” effect, making the bounces naturally fade within the cycle.

The length control sets the length of the waveform while repeats add repetitions of the wave, and delay sets the time between those waves.

These features in combination makes it easy to move from single tight envelopes to rolls, flams, clustered impacts and creative rhythmic patterns.

All main parameters got CV-inputs. A dedicated inverted output adds instant polarity flip.

Background

We like techno. For us its about solid kicks with defined transients and a fundamental low end that moves air without collapsing the mix.

Bounce is built to be performative and work at the source. By shaping events, accents and repetitions already at the control stage – it lets the mix breathe and leaves space where it matters most. Perfect for basslines, drums and transients."

Gene Synths GX

New synth day. I’ve been waiting patiently for this to arrive and it was worth every second.

Such a beautiful lo-fi melancholic sound with a load of modulation. I fell in love with the sound when I came across the Gene synths website last year.

Great solid build quality and probably the best knobs of any synth I own ❤️

The interface is unique and encourages exploration and experimentation.

Can’t wait to send it through a looper.
