BMC114 Diode Break Shaper Schematic Walkthrough

"This module splits a waveform into 5 bands of voltage ranges and then mixes those bands together with attenuverters. The break points between bands can be controlled with external CV. This allows for harmonically complex outputs that remind me of strings and woodwinds.

Compatible with 12V or 15V systems. The Pots are PCB mounted, but all jacks are off-board."

"I was asked a couple of times how does the Wave Multiplier works. I did this video hoping to answer the question the best I can.
Disclaimer: I'm not an influencer, nor I'm asking for money on Patreon. I don't have the equipment, nor I can spend days on making a video, so be aware that the quality of the video content might not meet your expectation(s) or even 2024 online tutorial standards. Myself I watch from time to time demos of new equipement from people I respect for the quality of their product demo or tuto ("loopop" comes first in mind). I have no idea how much time they spend on the making, but I can't imagine it not being enormous. Personally I'm simply trying here my best to share my experience and what I discovered about the Wave Mutliplier on the Synton Fénix II and IId, hoping it can be useful for all friends here watching my channel."

3D t-rex drawn on an analogue oscilloscope 🦖

video upload by Hexial

Curious if what we are hearing is the drawing or modulating the drawing per the video description:

"A 3D animated t-rex drawn on an analogue oscilloscope from 1982, with its redraw frequency modulated by MIDI from ‪@Ableton‬ Live. The amplitude of the audio left & right signals move the X/Y position of the beam which cycles through the vertices of the 3D mesh hundreds/thousands of times a second."

Update via Hexial: "The audio is creating the entire drawing you're seeing, moving the beam across the screen very quickly. The audio frequency is the number of times it's redrawing it per second."

Oscilloscope test #2 ft. Serum

video upload by Hexial

"I'm using 2 synths (Serum) routed into the X and Y axis of the beam, changing pitch/effects with sine waves and saw waves.

Beware, if you listen to it on headphones it might make your brain go weird because it's panned hard left & right 🫠👌"

Volume & Panning | Schlappy Patching with Stazma

video upload by SCHLAPPI ENGINEERING

"Episode 7 for Schlappy Patching!
Today we talk volume. Might seem boring but changing the volume of a sound over time result in dynamic, and it is actualy quite awesome! Also if you can change the level of something on one side of the stereo field, you get "panning" effect, without the need of a pan pot on a stereo mixer (you need two VCAs instead). Anyway we'll explore things volume related, using a drum mahcine and some sounds generated by the Three Body, mostly using Nibbler for stepped modulations.

Have fun watching!"

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.

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."
