Zonoxious Deep Dive Part 1: Project background & Frontend with VCV Rack

video upload by Ultratroninator 3000

"The initial video in a deep dive series provides background info and details how the Zoxnoxious analog synthesizer works. The focus is on the frontend, VCV Rack, and getting the signals required to run the synthesizer from VCV Rack out to a Raspberry Pi.

Zonoxious Deep Dive Part 2: Raspberry Pi Gadget Mode with 54 audio channels + MIDI

video upload by Ultratroninator 3000

"This second deep dive video on the Zoxnoxious synth goes into detail on the Raspberry Pi's gadget mode. The Zoxnoxious synth receives 54 control voltages as USB Audio and also USB MIDI for commands. This video shows how that is setup and used. To show the Pi gadget mode working I pull in VCV Rack and roundtrip signals from a host computer to the Pi."

Raspberry Pi based installation art: the melody that started at the beginning of the universe

"Modular synthesizer VCO. using Arduino uno r4 for technical verification.
Supports V/oct and audio output via built-in DAC.
Since this is a verification circuit, it is not recommended to make a module with this circuit as it is.

DIY Quad Mega Percussive Synthesizer

Note: Auction links are affiliate links for which the site may be compensated.
video upload by Àlex

via this auction

"4 MPS (Mega Percussive Synthesizer, by Thomas Henry):

- 4 equal percussion voices. Each one is 1 MPS.

- Individual trigger and CV (for shell pitch) inputs.

- Independent outputs for each channel.

- Output on the rear panel with the mix of the 4 channels.

It's a DIY project from a few years ago, maybe 10. I haven't used it almost at all. Although the condition of the panel is not the best (it has some scratches, the silkscreen is lost at some point, etc.), in terms of sound and control it is perfect. Unique sound, you won't find anything like it on the market (unless you buy 4 MPS and put them in a Eurorack case.)"

Roland Juno-106 Synthesizer Troubleshooting/Repair Quiet Voice

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2024

Today I'm investigating an issue with a Roland Juno-106. Voice #4 is a lot quieter than the others. And it's not a calibration issue. 99% certain it is NOT the brand new voice chips I put in as seen in a previous video. Troubleshooting will confirm that statement. So what else could it be? Maybe something EVERY 106 owner will want to be pro-active about mitigating?

This video is posted for general information about my experiences. Always observe safety working on electronics, and never tinker around inside power supplies without first unplugging the power cord. De-soldering components on the Juno-106 must be done VERY CAUTIOUSLY to avoid lifting very tiny delicate traces. If you're not sure about anything, there's no shame in taking your instrument to a qualified service technician.

Paia 2720 + 4700 (1970's DIY modular synthesizers)

video upload by Tinfoil Cat

"I've been telling myself for too long that I should post more Paia videos. This is an old video shot before I fixed the keyboard on the 2720 (broken sample and hold as you might hear). The main part is 4700, the 2720 helps out with a fourth VCO. The spring reverb is a little noisy.

These were available as kits from Paia starting in the 1970's. The 2720 is closely related to the 2700 that arrived on the market over 50 years ago!"

Interesting side note via sdiy.info:

"Frac rack, FracRak or Frac, from Fractional Rack, is the modular synthesizer format designed by John Simonton of PAiA. It has a mainly USA following largely through the popularity of Blacet modules.

Like the Eurorack format, Frac is considered a 3U format..."

Creating a midi controller for the microKorg

video upload by Dean Coyle

"I really do love the microkorg, I think the features it brings at the price point were amazing when it first was released. It gives you enough of a taste of important tools synthesizers use to create sounds. I think it could be a great beginner synth, but then again it is still used by LCD soundsystem to the Killers.

I set myself the challenge of creating a midi controller to help unlock features of the synth and make it more user friendly. My goal was to move away from the matrix tool and have a control for every possible control.

Ok on reflection this is turning a microkorg into a ms2000.

Though I do find the synth a lot more enjoyable to play and feel more in control of shaping the sound.

Normally I would cover more of the coding and electronics, but I don't think I can do Notes and Volts justice: https://www.youtube.com/c/NotesAndVolts

Overall it was a fun project, there are a couple more synths that need this treatment.... watch this space."

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/"

I'm currently hard working to get new PCBs and casing done - so you can purchase an already assembled NI404 - sadly, this takes a while. If somebody is into PCB / KiKAD and likes to contribute: I could need some help!"

[$5] DIY eurorack modular synth Dual Slew Limiter

video upload by HAGIWO

"My 74th original eurorack modular synth DIY projects.
Dual Slew limiter , I aimed for simple functionality with few components.

Please support me to continue projects.
In patreon you will find content about my background , technical information and CAD data.

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.
