Arduino VGM player with rough SN76489 emulation - sneak peak of a video game music chiptune project
video upload by Marcel Licence
"Similar to the previous project I wanted to implement the playback of a new file format.
In this project VGM files are played on different platforms (decompressed VGZ files).
To get any audio I've implemented a very rough emulation of the SN76489 sound chip.
It has three square wave outputs and a noise channel.
The noise channel does not completely work as intended yet.
You might hear some deviations to the expected audio of the video game music.
This project is implemented in Arduino.
After adding some more features I will make this project available soon.
Used VGM files:
- Sonic the Hedgehog 2 - 07 - Sky High Zone.vgm
- Global Gladiators - 02 - Techno Tune.vgz
- Global Gladiators - 03 - Duelin-Dance.vgz
- Global Gladiators - 04 - Dance Tune.vgz
- Lemmings - 01 - Title screen.vgm
- Lemmings - 02 - Can-Can.vgm
- Lemmings - 03 - Levels 2 & 19.vgm
- Lemmings - 04 - Levels 3 & 20.vgm
- Lemmings - 05 - Levels 4 & 21.vgm
Files were originally in .vgz format and I renamed them to .vgz, decompressed them
and finally renamed the uncompressed files back to .vgm before I could play them.

BAF 2024: Dogbotic Labs - Synth Building Workshops
video upload by sonicstate
"At Buchla and Friends 2024, Sonic State had the opportunity to chat with Sean from Dogbotic Labs who offer online workshops for electronics, where participants receive a kit of materials and learn how to build their own circuitry over 10 weeks on Zoom. The workshops have attracted participants from all over the world, fostering a sense of community and collaborative learning. Sean, who is a composer and video artist performing under the name Isorhythmics, emphasizes the importance of experimentation and creativity in electronics, highlighting that it's not necessary to fully understand how things work as long as they can produce cool results.
One of the main workshops offered by Dogbotic Labs is the *DIY Synths* workshop, which teaches participants how to build their own basic synthesizer from scratch. Another popular workshop focuses on building a drum machine with a patchable interface. While the designs may seem complex, Sean encourages participants to customize their creations according to their own artistic visions.
Unfortunately, the kits are currently only available for purchase as part of the workshops, but Dogbotic Labs is planning to start selling the kits separately in the future. https://dogbotic.com/"

dual octaver
video upload by e j
via Optotronics
"The octaver is a great addition to the dual CEM VCO module (the square wave output should be routed to the pulse input).
It's based on the original Thomas Henry's VCO Maximus. It is a perfect tool for generating additional musical fifth or suboctave tones. Moreover octaver 2 input is connected to the output of the octaver 1 for additional divisions! Of course you can use them separately as well. The great thing is that this module allows you to create very interesting soundwaves and rhytms...
According to Thomas Henry : 'The pulse signal is routed to an XOR/flip-flop arrangement which generates an additional musical fifth or suboctave tone added in. You can think of this in terms of harmonics, or if you wish, as a definite harmony playing in tandem, e.g., a C note with a G note mixed in.
The pulse output from the CEM3340 is sent to Schmitt trigger to sharpen up the signal a bit. The firmed up pulse then goes to switch 'interval' which lets you choose between the addition of a fifth or an octave derived pitch. If numbers are your bag, then think of these as divide-by-1.5 and divide-by-2, respectively. On the far end, switch 'octave select' can further halve things to divide-by-3 and divide-by-6, i.e., a fifth and an octave one octave lower yet.
Polarity switch lets you add or subtract the subdivided signal from the original pulse, effectively doubling the number of waveforms possible. The output of the flip-flops is sent to one side of the blend pot, while the other side t is fed by an isolated version of the original pulse.'"

Description (Google translated):
The 75th work of my own modular synth.
One of the most basic modules of a modular synth is the Slew Limiter. Eurorack's most popular module, Make noise Maths, also has this slew limiter function.
I have also created modules with Slew limter functionality, but since I have never created a Slew limiter itself, I decided to create one.
Product specifications
Eurorack standard 3U 6HP size
Power supply: 15mA (+12V), 15mA (-12V)
Dual Slew Limiter with two types of functions.
Priority is given to low price and fewer parts.
top of module
Slew Limiter allows you to select the slew rate range from three types.
Select 3 types of range with the toggle switch.
L range: Assumed to be used for slow CV such as LFO
M range: Assuming the use of pitch CV portamento
S range: Assumes the use of an audio frequency low-pass filter
Control the slew rate with Pot.
Supports bipolar input.
Since the accuracy of the output voltage with respect to the input voltage is high, it can be used for V/oct pitch CV.
module bottom
Slew Limiter allows you to set Rise and Fall slew rates individually.
It is assumed that ASR envelope generator will be used.
Supports bipolar input.
Due to the circuit, the accuracy of the output voltage with respect to the input voltage is low. The use of V/oct pitch CV is not assumed.

Audio demo at 3:35.
"In today's episode, I build and demo a DSP-99 based eurorack module I found through a Modwiggler forum. Let me know what modules I should build next!
Check out the DSP-99 Modwiggler forum project here:
https://modwiggler.com/forum/viewtopi...
DSP-99 boards on aliexpress:
https://www.aliexpress.us/w/wholesale..."
"DSP-99 is based on Wavefront AL3201 DSP chip, Cirrus Logic CS4220 audio codec and Atmega8AU for control and display.
It has 100 programs, although many of them differ little. Nonetheless it's quite good investment for this money.
As DSP has rather low signal level tolerance (compared to eurorack levels), clipping indicator was included. Signal indicator was also added for convenience."

Picophonica — A Raspberry Pi Pico synth for a toy keyboard, with instrument presets and Midi out
video upload by Turi Scandurra
"A friend gifted me a cheap toy musical keyboard. The sound quality was atrocious, and it could only play one note at a time. So I removed its circuitry while keeping its enclosure, speaker, and keybed, and with some tinkering and a Raspberry Pi Pico I turned it into something usable.
I integrated a software synthesizer into the Pico. It's pico_synth_ex by Ryo Ishigaki - ISGK Instruments. The new engine boasts two oscillators, featuring descending sawtooth and square waveforms, a customizable filter with resonance control, cutoff modulation, a Decay-Sustain amp envelope, and an LFO for added modulation possibilities.
This video shows the makeover. The soundtrack is entirely played on the Picophonica, recorded one instrument at a time through the new audio out port.

video upload by Oficina de Sonido
Currently on Kickstarter
Oficina de Sonido created by Daniel Llermaly is a project centred on designing music-making tools with Open source in mind. Based on Mexico City
My First Modular, your gateway to the Eurorack synths.
We know that Eurorack Synthesis (or Modular Synthesizers) can seem inaccessible due to its reputation for being expensive and complicated.
That's why we decided to design a modular system that is affordable without compromising on quality. My First Modular is a low cost eurorack modular system, with a precise selection of modules for beginners, versatile and with simple and colorful interfaces. As we are designers and musicians we have made an instrument with the basics to express your musical creativity.
This Opensource Synth design proposal aims to be the most accessible eurorack modular system that exists, where anyone with a little knowledge can use our templates and codes to produce their own modules and, like us, improve them and make them available to the whole community.
This crowdfunding project will allow us to finance the development and manufacturing of the first complete systems, therefore the current price is only for this campaign. Most likely in the future the price of the system and the modules may vary.
Key Features
Affordability: We have designed our Eurorack Module system to be the most affordable option for electronic music lovers. We believe everyone deserves the opportunity to experiment with electronic sounds without going broke.
Ease of Use: Our system is beginner-friendly, which means that even if you're new to Eurorack, you'll be able to start creating music right away. No advanced technical knowledge is required. We deliver the modules pre-built without the need for soldering.
Sound Quality: Despite its affordable price, we have not sacrificed quality. We have carefully selected modules and resources that guarantee a good sound and a satisfying musical experience.
Open Source: crowdfunding this project aims to design an opensource system supported by and released to the community.
