Talk ‘N Learn Alphabet – Unleashing Demons & Chipmunks

Making a sawtooth and sine from a triangle wave - converting waves the opposite way as usual .

video upload by organfairy

"I switch it on at 4:35 and run it with a sequencer at 5:25.

After having made the 'classical' sine wave generator • Analog sine wave generator [video below] and the 'sort of digital' sine wave generator • Synthesizing waveforms with a frequency di... [posted here] a couple of months ago, I thought I should do a sine wave the third way - if not for other reasons it could be to say that I have done a sine wave trilogy: Start with a triangle and convert it to a sine wave.
This is a method that was often used commercially. If a function generator has both triangle and sine it is often made this way, and the XR2206 component that is often found on cheap tone generator kits works this way internally. I am not sure about the EMS VCS3 but I have a suspecion that OSCILLATOR 1 is also based on this idea as it can make saw and sine at the same time.
I do start with making a sawtooth wave though. I have not seen this method used before, but I doubt that I am the first to have done it.

The music is sort of a mood composition where I focused more on the mood and the sound construction than the melody, which is rather unusual for me as I consider myself a melody focused music tinkerer. Whatever it is I made it on my Roland D-20."

Analog sine wave generator

video upload by organfairy

"I test run it at 4:15

After making that "somewhere in the swampy wasteland between analog and digital sine wave generator" last week, I decided to try and make a classical analog sine wave generator - just for the fun of it.
Sine wave generators are sort of an interesting thing: They are basically just an amplifier connected back to front through a filter, but the amplifier needs to be regulated in some way, otherwise the sinewave will get distorted to a point where it is often more a square wave.
This sine wave generator is not controllable from a keyboard like the other one I made, so it is more for modulation purposes or maybe if I one day take up the obscure art of musique concrete.

The musique ridicule that I play during the video is something I fumbled together playing my Korg Rhythm 55, Elka X-1000, and Roland D-20."

Antonus Step Brother DIY - Test Drive w/ A2600, SR-909 and Fractal VP4

video upload by Tumeni Knobs

"It took a couple of months, spending a few hours on weekends, but I got it done! And it's very cool. This demo is pretty rough, but highlights a bunch of the key features of the Step Brother and the "performability" it offers.

See my full build log here: https://www.modwiggler.com/forum/view...

In this setup, the Steda SR-909 is sending midi clock to the Step Brother and the VP4 to keep them in sync. Step Brother is configured to run 2x8 step sequences on channels A and B. Channel A quantized CV output is sent to the 2600 mult and then routed to the CV inputs of oscillators 1 and 2. Channel B quantized CV output is sent to the CV input of oscillator 3.

Step Brother Gate Bus 1 is routed to the 2600 main gate input and triggering the 2600's ADSR envelope. SB Gate Bus 2 is triggering the envelope on the Step Brother and audio out of Osc 3 on the 2600 is routed to one of the VCAs on the Step Brother which is controlled by the Step Brother's envelope. That is then routed back to the 2600's mixer.

Audio out of the 2600 is routed to the VP4, and then routed to the ALA Bartender along with the audio of the SR-909. Output from the Bartender is sent to the iRig Pro and recorded on iPhone with the video.

Cheers!"

First try at making music for FM synthesis

video upload by MIDI IN

"I'm very happy that Ed Brindley has made this FM sound module for the RC2014 and similar computers. This is the technology used in early PC soundcards and synthesisers like the DX1000. This is my first go at tracking music for this sound card. I used Furnace Tracker, exported to .vgm and ran Ed's music player to play it. You're hearing the capture from the new sound card.

Stranger Things 'Kids' Synth Cover using Prophet-6 and T-16 (based on ARP 2600)

video upload by Nitecaller.

"#StrangerThings has given me so much life and inspiration over the last decade, but maybe more importantly it gave us one of greatest soundtracks ever, composed by Kyle Dixon and Michael Stein.

I’ve been learning the parts and playing this theme for years now and it never gets old. Feels good to finally put together a proper cover of it. Using only two synths; the Prophet-6 (which the composers use heavily) and the T-16; my custom-built synth also inspired by the gear of the composers (ARP 2600). [see the Nitecaller label for more]

Prophet-6: Lead parts and SFX
T-16: Bass and outro arpeggio

Designing and troubleshooting a module | Instruō - ceithir

video upload by Instruō

"Hello and welcome!

👉 • Instruō - ceithir | Project Overview
(Here is an introduction to the ceithir with more detailed project background and sound examples.)

In 2015/16 Instruō began as a video project. Specifically a time-lapse of me designing the original troika module.
Ten years later, I’ve returned to that idea with ceithir, a winter holiday project I designed with video documentation in mind.

This video shows the process of ceithir's initial prototype design.
The full module interface was the first part of the process. That stage has its own video feature:
• Designing a Eurorack Module interface | In...

In this first hardware iteration I focussed on the core functionality of a single channel version of the filter. The majority of the circuit was tried and tested in the I-ō47 module. But I made several additions to the design for ceithir:
Temperature compensation of the core
Dedicated oscillator mode with stable peak amplitude
Stereo output utilising modulated phase shift to create discreet L/R
Additional mode morphing to incorporate band-pass response

I forged ahead with a hardware design where priority was not placed on manufacturability of the prototype. It is a two board layout requiring circuitry distributed between two parallel PCBs. This used many header connectors but provided a large "canvas" to lay out all elements of the circuitry in a sectional way that allowed for ease of navigation when it inevitably came to troubleshooting and fixing mistakes/making refinements.

New Open Source Virtual Pipe Organ Project: Rusty Pipes

This one is in via DS:

"Hey Matrixitians!

I'm writing in to announce a new MIDI-controlled Virtual Pipe Organ software called "Rusty Pipes".

It's a sample-based organ synth with support for GrandOrgue and (unencrypted) Hauptwerk sample sets. It features 32 bit internal audio mixing, full MIDI support with extremely flexible channel routing, integrated audio and MIDI recording of performances, convolution reverb, and an innovative sample streaming mode that makes it possible to play very large sample sets with a minimal amount of RAM, yet without increasing latency!

Other unique features include a REST API for things like pulling stops - great for people who like to build physical consoles - and optional text mode support (via Ratatui) which makes this ideal for running on headless setups or on a RaspberryPi.

Rusty Pipes is a clean-room implementation written 100% in Rust, available free and open source under the GPL v2. Version 1.3.0 supports over 20 languages including Latin and Klingon, and is available for Linux, Mac and Windows. Debian and Arch (AUR) packages are provided as well.

Szumofon. Шумофон.

video upload by VladimirRadiomay

"Звуковой инструмент Шумофон. С добавлением тональности.
Когда-то в польском журнале Радиоэлектроник, в 1984-м году была
опубликована схема клавишного инструмента Szumofon.
Потом её опубликовали в журнале Радио. (1985. N10).
И вот по идеям этого Шумофона сделан такой инструмент.
Как соло и отдельно, он вряд ли самодостаточен и интересен, но с ревербератором
и в комплекте с какими то другими инструментами и для эффектов в какой то композиции
вполне может быть использован."

Googlish:

"The Szumofon sound instrument. With added tonality.
Back in 1984, the Polish magazine Radioelektronik published a circuit diagram for a keyboard instrument called the Szumofon.
Later, it was published in the magazine Radio (1985, No. 10).
And this instrument is based on the ideas of that Szumofon.
As a solo instrument, it is unlikely to be self-sufficient or interesting, but with a reverberator and in combination with other instruments, and for effects in a composition, it can certainly be used."

Noodling with reSEMble

video upload by Randy Piscione

"PM Foundations recently re-stocked a limited number of reSEMble PCB/Panel sets, and this may very well be the last time. If you’re unfamiliar with reSEMble, it is a tribute to the Oberheim SEM, but more of an SEM 2.0. Have a look at the other relevant videos on my channel for more sounds and info. If you want to build a reSEMble, go here: https://www.tindie.com/products/pmfou...

This is not the most visually exciting video, I was really more interested in demoing the sound. reSEMble provides the leads, odd percussion and sound effect bits. Drums are courtesy of an Alesis SR-16.

The first part of the video (first verse I suppose) uses the reSEMble in a configuration that duplicates the SEM – two VCOs, LP VCF, 2 EGs and a triangle LFO. Bass for the verses is from a Behringer Minimoog and a custom-modified Behringer TD-3. Chords for the verses comes from a 1980 dual manual Prophet 10.

The first chorus adds a third VCO and sine LFO. Bass is provided by a Minimoog (first re-issue) and the chords are again from the Prophet 10. The second verse brings in the wavefolder. The second chorus is similar to the first. The odd percussion and sound effect stuff bring in some audio rate exponential FM. The final chorus uses the wavefolder with the VCOs mixed in."
