Poly MOTM Synth Noodles With A Side Of Oscilloscope


video upload by John L Rice

"Another test after modifications.

Only Synth Tech modules used:
MOTM-650 MIDI to CV
MOTM-300 VCO x 4
MOTM-800 EG x 4 (in only two spaces)
MOTM-190 Dual VCA x 2

Actually I used a custom multiples and two Moon 526 mixers for the oscilloscope feed.

PreenFM2 Eurorack module, clean waveform, sine, square


video upload by VanDaalElectronics

"This video demonstrates how to get clean waveforms out of your PreenFM2.
In short: turn off your operators and keep one that will provide the needed shape.
In this video I show how to get nice simple clean waveforms out of your PreenFM2.
I am using a MIDI keyboard.
First part shows how to get 1 voice mono, no Velocity and no Glide. This is done only for the video as Oscilloscope doesnt show it that clear in poly settings.

Then I start turning off operators by switching the OP() button.
OP1 Shape: Sine. OP2 Shape: Off. OP3 Shape: Off and so on.
Once all the operator shapes are Off I can start playing only OP1 and hear its waveforms.
This is very handy if you start learning FM or want to have simple waves.

You still have the ADSR in action.

NB: PreenFM2 Eurorack module outputs eurorack levels, dial down the volume for line level use."

"Delights of Kyoto" - Akai MPC + Roland SH4d + Roland OpSix + Arturia MiniFreak +


video upload by Patrick Manderson

"'Delights of Kyoto' was recorded live late Saturday afternoon on 3/2/2024 using a MIDI sequencer and a room full of synthesizers and audio gear. All automation was programmed into the Akai MPC X. Some manual tweaks on the Midas console was made during recording.

Inspired by YouTube videos of Japanese restaurants and diners - 'Kyoto' was developed using the Roland SH4d as a drum synthesizer, paired with my usual synthesized drum kit on the Korg Radias and some excellent Hydrasynth patches developed by @Jexus. Voice synthesis on the Arturia MINIFREAK and various pads, plucks, stabs and noises provided by the Sequential REV2, Roland JP-8080, Korg OpSix among others.

The most significant addition to this music is a careful degree of live mixing using the Midas Venice F24 running a stereo mix through the Warm Audio Bus Compressor.

[$25] DIY eurorack modular synth Hard/Soft SYNC VCO with Arduino uno R4 , digital VCO


video upload by HAGIWO

"My 76th original eurorack modular synth DIY projects.
Arduino UNO R4 based digital VCO , it has Hard/Soft SYNC function.
Since the SYNC frequency is controlled by CV, SYNC sound can be created with fewer modules.

"Includes patch cables, USB power cable, rca to 1/8" cable, ribbon cable & original packaging."

This is a bit of an odd post. I spotted Anabrid's Analog Thing Analog Computer on Reverb and was curious what it was, as it has not been featured on the site before. Below you'll find some info from Anabrid along with a user video featuring some audio.

Little Impro with THAT by Analog Thing

video upload by JesterN

"Playing THAT:: Bernd Ulmann's beautiful analog computer. This is Sprott SQM Model an example of a simple three-dimensional chaotic flow with a quadratic nonlinearity. The model consists of three coupled differential equations. Translating and solving equations through circuits is feels very organic. I was used to do this on paper, and had found it quite simplistic to approximate it digitally, just using brute force computer iterations."


via https://the-analog-thing.org

THE ANALOG THING (THAT) is a high-quality, low-cost, open-source, and not-for-profit cutting-edge analog computer.

THAT allows modeling dynamic systems with great speed, parallelism, and energy efficiency. Its use is intuitively interactive, experimental, and visual. It bridges the gap between hands-on practice and mathematical theory, integrating naturally with design and engineering practices such as speculative trial-and-error exploration and the use of scale models.

Dynamic system modeling on THAT can serve a variety of valuable purposes. It may help understand what is (models of), or it may help bring about what should be (models for). It may be used to explain in educational settings, to imitate in gaming, to predict in the natural sciences, to control in engineering, or it may be pursued for the pure joy of it!

A DIFFERENT PARADIGM

Analog computing is one of three major computational paradigms (analog, digital and quantum). As digital computing approaches the limit of Moore's Law, analog computing offers a strategy to diversify today's digital monoculture. Analog computing is:
ideally suited for dynamic systems modeling
ideally suited for neuromorphic AI applications
significantly more energy-efficient than digital computing
inherently safer than digital computing in the face of cyber threats

THE ANALOG THING is designed to allow an extensive range of analog computing applications with a small set of calculating elements.

5 INTEGRATORS
Circuits that perform integration over time.

4 SUMMERS
Circuits that add inputs continously.

2 COMPARATORS
Circuits that compare inputs to support conditional functions.

MASTER / MINION PORTS
Interfaces that allow daisy-chaining mutiple THATs to create arbitrarily large programs.

8 COEFFICIENT POTENTIOMETERS
Rotary knobs to provide user-defined inputs.

2 MULTIPLIERS
Circuits that multiply inputs continously.

PANEL METER
A digital panel meter for precision measurements of values and timing.

HYBRID PORT
An interface for controlling THAT digitally to develop analog-digital hybrid programs.

DYNAMIC SYSTEMS MODELING

With THE ANALOG THING, you can model dynamic systems including:
market economies
the spread and control of diseases
population dynamics
chemical reactions
mechanical systems
a variety of mathematical attractors

COLLATERAL LEARNING

As collateral learning benefits, THAT offers introductions to:

CALCULUS
Inseparably linked with rates of change and the accumulation of quantities, analog computing offers a practical approach to differential and integral calculus.

ANALOG CIRCUITS
With computing elements built around operational amplifiers, analog computing enables users to gain a hands-on understanding of analog circuits.

CONTROL ENGINEERING
Applicable in adaptive control systems, analog computing offers a practical introduction to control engineering.

SERGE GTS (for eurorack) - Waveforms


video upload by Serge Modular | Random*Source

"How does a slope generator sound? Here two Serge GTS are used as a Complex oscillator that is run into a Variable Slope filter (VCFS), playing a simple MIDI loop via 1V/Oct. Single patch, just playing with a few knobs...

The Serge GTS is a complete redesign of the famous Serge Dual Universal Slope Generator (DUSG) by Serge himself - with a new core, optimized for speed and tracking. Like some of the clones it can be used for CV, but provides exceptional audio performance: transient rise times as fast as 12µs and a maximum cycle speed of 28kHz."

Norman McLaren's hand-drawn sounds


video upload by Robotussin Vintage Synths

"Scottish-Canadian animator Norman McLaren developed a technique of painting onto the optical soundtrack area of the film negatives of his animations.

The shapes would then make drones and buzzes when played through a special type of projector. He used the technique to create experimental soundtracks to his animations.

It's similar to Daphne Oram's technique of turning shapes into sound – though hers, which she called Oramics, was more complex, with dedicated machines that read shapes on the entire area of the 35mm film, rather than just the little strip that contains the soundtrack.

You can see the results in the third video above, an extract from McLaren's film 'Dots', which employs the technique.

McLaren – born in Scotland in 1914 – worked for the British Post Office's film unit until around 1939, when he moved to New York, then to Canada in 1941, where he produced animations for the National Film Board, before setting up an animation studio at the École des beaux-arts de Montréal and the Ontario College of Art.

There he produced around 70 films, much of it highly experimental and strange. He died in 1987 aged 72."

This also reminds me of the Optigan.

Norman McLaren is mentioned in this book: Vector Synthesis: a Media Archaeological Investigation into Sound-Modulated Light

Lunchbox Voice Prototype gets patched ! - Low-Gain Electronics | 4U Modular


video upload by LowGainElectronics

"Had a shop visit from the talented @helenastndc all the way from Spain/Sweden yesterday! We had a great discussion about synthesizers, design/diy and education. She got a little time to patch on the lunchbox voice system prototype on my test bench. We didn’t get a chance to get a proper recording of it but I fired it up where she left it and grabbed this recording of it this morning. Just turned a couple of knobs during the recording to see what sonic journey it would take! Hope you enjoy! Headphones recommend for full fidelity!"
