The All-Dancing Accelero-Gyro DIY Triple CV Controller

video by Izhar Ashdot Sound & Vision

"As part of my fascination with Sensors, I built an Accelerometer-Gyroscope based controller for modular synths that outputs 3 CV streams to control any parameter in your synth setup.

In this video I'm controlling the Pitch of an oscillator with the Pitch axis, the cutoff frequency of a filter with the Roll axis, and the resonance of the same filter with the Yaw axis.

I 3D printed an enclosure for the GY-521and I wear it like a watch using 2 velcro cable ties."

DIY Synthesizer with ESP32 (super/hyper saw, aliasing free oscillators)

video by Marcel Licence

"This video shows some impressions of using the ESP32 for a little synthesizer project.
All processing is done on one core with sampling rate of 48kHz.
I've connected a master keyboard via MIDI to a serial input.
The synth actually can play 6 voices together (also with 6 oscillators per voice in unison/detuned mode).
The oscillators are aliasing free (wave forms had been generated in advance to avoid fold back of frequencies above nyquist).
Rough ADSR for velocity and filter is implemented.
---
I am preparing a little arduino project for sharing. It will be available soon..."

minipops 2O2 ~ breakbeats 'n' stuff

wildchurch

"a build of jan ostman's O2 minipops arduino drum machine with different samples and patterns

first a quick run through of the patterns/samples:
~ there are 12 patterns selected by push buttons
~ i've added kick, snare, tom, hi-hat and cymbal derived from 808 and casiotone! samples while retaining the original cowbell, clave and maracas

second part shows some MIDI clock sync'ing along with triggered filters via the analog reset out
~ an arduino MIDI sequencer/arpeggiator: http://brendanclarke.com/2014/04/23/a... drives a Yamaha WT11 with patches
~ the WT11 stereo out runs through separate filters for left and right
~ the minipops reset out tiggers an ADSR (via clock divider and trigger to gate conversion)
~ ADSR output goes to buffered multiples to produce two signals - one to each filter's cv input"

Revisiting the Minty Synth 2.0

poorness studios

"About 3 years ago, I built a Minty Synth 2.0 kit. While I had a lot of fun with it at first, it's been sitting for a year or more. I decided to revisit it recently and I forgot how much fun this little gadget can be. I decided to make a video to share with all of you. It's a really cool little kit.

Super-Simple "Taurus" Pedals Using Arduino

Pete McBennett

"OK, this is just something I slapped together for fun. It's built on a clip-board from the Dollar Tree store, with the clip removed. The "pedals" are just strips of PC board with copper on the bottom, and screws underneath for contacts.

It's programmed for a simple pentatonic scale, because I could only fit five across with enough spacing. The upper left pedal is to cycle through five different scales, and the upper right pedal is a mute switch.

There are two RCA jacks mounted on a piece of aluminum. One is for audio out, the other is trigger out. They go up to my filter (same one as my previous videos), which is conveniently located up on the desk. I'll upload more info and the code in another video, if anybody wants to experiment with their own version."

Bleep Labs' New intro to Arduino Course - "Creating light and sound"

Bleep Labs

"Bleep Labs' new online dadageek course, 'Creating Light and Sound' starts Sept 21st. This time we’ll learn how to code in the Arduino platform using a 8x8 RGB LED screen, accelerometer, touch sensors, and more, all with the powerful Teesny 3.2. Sign up now for 20% off.
https://www.eventbrite.com/e/intro-to...

Here’s a quick video showing what you can do with the solder free kit that’s included in the cost of the course.
It’s tricky to shoot video of these bright LEDs but they look great in person.

The first and last sections are a generative device which creates random-ish arpeggios and changing colors to go with them. Controls changes filters, colors, delay feedback, and the rate of the arpeggio. The audio is coming straight from the device.

In the second section a simple bitmap scrolls and loops. Colors are scroll speed are controlled with the knobs. Rather than creating sound directly this one sends MIDI notes and CCs to VCV rack.

In the third section two bouncing balls are simulated with random notes chosen each time they hit the wall. Of course there is also a tape delay effect. All sounds generated by the device.

Check out the code for these devices here. https://github.com/BleepLabs/dadageek...

When you take the class you get seven, three hour sessions in a class that is capped at fourteen students. The class is also just the beginning. I encourage my students to keep contacting me with their questions and ideas long after the class is done.

Check out the @dadageek site for info on scholarships."

The HARMONOGRAPH SYNTHESISER & How to Sequence Your Eurorack System with a Record Player

Lomond Ziggy Campbell

This one is in via Joshua. Links to additional info in the description below.

"I built an 18th century harmonograph and connected it to a 21st century modular synthesiser.

A harmonograph is an old scientific device that uses pendulums to create illustrations of harmonic motion, called lissajous figures. On this harmonograph each pendulum is connected to a sensor which triggers different elements of the synthesiser so that every time it makes a drawing, it also plays an accompanying synth soundtrack. There's also a contact mic on the drawing board to pick up the sound of the pen.

It uses three pendulums - two connected in a linear way to the pen and one rotary pendulum connected to the drawing board. You set them all swinging, lower the biro pen to the drawing board and let the pendulums run down over a period of about 5 minutes, after which both the unique drawing and soundtrack are complete.

I recorded an album of the first 18 drawings which can be downloaded from my bandcamp page:
https://lomondcampbell.bandcamp.com/a...

You can see the drawings here:
https://www.lomondcampbell.com/harmon...
I used proximity sensors and an Arduino to get the harmonograph talking to the synth. You can find the code, examples of drawings and sounds plus more information about the project on my website:

HOW TO SEQUENCE YOUR EURORACK SYSTEM WITH A RECORD PLAYER


"Convert any turntable in to a programmable rotary gate sequencer for modular #Eurorack systems with just a few components and a simple bit of coding.

- Control tempo with your turntable speed control!
- Sample from a record while staying in sync!!
- Build yourself two and beat match with dual turntables!!!
- Make your live #modular set more visual so thousands of people come to see you play instead of your three best pals.......TRUST ME!

Components:
x1 #Arduino Nano
x4 proximity switches / reed switches
x4 10K resistors
x4 3.5mm mono jacks
x4 LEDs (optional)
x4 100 Ohm resistors (optional)
x4 SPDT toggle switches (optional)
x1 vero board
.... + some camdenboss terminal blocks if you're in to that kind of thing.

Here's the link to the code, schematics and diagram:
https://www.lomondcampbell.com/projec...

For my device I used some flush cable proximity switches I got from a lab clear out. They're no longer available but this is pretty much the same thing:
https://uk.rs-online.com/web/p/produc...

The neodymium magnets I used are 4mm diameter by 2mm deep and any mild steel sheet metal will do for the plate.

I included some LEDs in my circuit as visual indicators plus some toggle switches so you can mute each channel, but neither are necessary."

The Arduino-Solina V2.0

Andreas Remshagen

"I experimented with Arduino-Synthmaking and found an Arduino-Solina String-Synth Device running with Midi made by Morocco Dave and Jan Ostman. I made a modification by adding a second Arduino for building a Stereo-Device for a lusher String-Sound.

Yah, i know its not a real solina or a strings synth but i never had build such a Device easier and cheaper.Its a nice Solution for using strings-effects. I only use the clean sound in this video-if you take effects as reverb, delay, phaser and a filter you will get a very nice sound

Eurorack polyphony in 52 HP (single filter)

Published on May 24, 2020 joeSeggiola

"My personal take on polyphony in Eurorack. Recorded in spring 2020.
DIY MIDI to 4x CV/gate interface: https://github.com/joeSeggiola/arduin...
MI Stages custom firmware: https://github.com/joeSeggiola/eurora...

Patch notes, from left to right:

- A DIY MIDI interface (link above) allocates notes polyphonically from the keyboard into four channels of CV/gate. The additional top-most gate output is a combined OR.
- CVs are sent to Chord v2 in Unison Poly Mode: each oscillator is controlled independently by its own 1V/oct input.
- Gates are sent to Stages, which runs a custom firmware (link above) that generates five identical envelopes.
- Veils uses four of these envelopes to drive one VCA for each of the four voices coming from Chord's individual outputs.
- WMD SSF Pole-Zero filters the final mix from Veils; its cutoff is modulated using the fifth envelope from Stages, the one triggered by the OR-gate signal.

[ 0:00 ] Overview, simple melody
[ 1:13 ] Filtered chords
[ 2:04 ] Overlapping arpeggios
[ 3:44 ] Wavetables exploration

I'm not claiming this is the way to get polyphony in Eurorack, I'm just sharing the result of my latest DIY and coding projects."

Arduino Breadboard Glitch Storm DIY Synthesizer Demonstration

Published on May 1, 2020 The sound of Non Silence

"2 x Glitch Storm Diy Synths playing together.
One is on an original Pcb and the other built on my breadboard copied from online schematics.

Original Design by the Spherical Sound Society https://www.tindie.com/stores/jc2046/"

"Glitch Storm is an exploratory synth that can be build and soldered even for total beginners. It produces a plethora of blips and blops ranging for chords, techno rhythms to alien soundscapes and FXs.

At its core is a Bytebeat synth but this one is interactive. You play it tuning into frequencies and soundscapes. You have four dimensions in it to explore, three ones via the knobs and a forth one via buttons, changing the equation that is playing.

The unit is able to be played as a standalone or in the context of one studio or modular.

Is quite good for pinging filters too and can enter in an easteregg mode for it to trigger gate outs for synchronizing external gear with it.

You can order the bare PCB, the Partial Kit, the Full Kit and a Build unit.

Users ordering only the PCB will have to source the rest of components and program the Arduino Nano.

The partial kit includes a PCB + a preprogrammed Arduino Nano, so the user will only have to source the rest of components.

The Full Kit has everything needed to build the synth.

There´s a github link where you can find the BOM, the schematics of the project and the compiled file for programming the Arduino Nano."

Evening Tide - An Ambient Synth Improv (Blofeld, Specular Tempus, Arduino, reface CP)

Published on Mar 17, 2020 Lanthan O'Ide

"A relaxed jam session with FM electric piano sounds, spiced up up a little pitch bending thanks to a DIY-MIDI-controller.
Enjoy! ^^
================================
For those playing along at home:
The key is G major, the tempo is not fixed and changes during the track.
================================
For those interested in the wiring:
I'm using the reface CP only as a master keyboard this time. It sends its MIDI-signals to my custom MIDI controller, which passes them on to the Blofeld.
Said controller has an Arduino inside, and also has inputs for sustain and expression pedals. It also feeds MIDI signals to the Blofeld whenever I use the pedals.
In this case, it is translating an epression pedal to pitch bend commands.
This allows me to bend down my sounds without taking my hands of the keys! :D

...and the yellow lights show the position of the pedals, in case you are wondering.
The left one shows the sustain pedal, the four right ones the expression pedal. :)

Anyways, continuing with the setup description:
The audio from the Blofeld is passed through my trusty Specular Tempus, the output of the ST goes straight to my audio interface where it is recorded.
================================
For those interested in the sound design:
Yes, those are real fm sounds, in that they are created by a sine wave oscillator being frequency modulated.
The amount of frequency modulation is set by the filter envelope.

However, the modulating oscillator uses a wavetable. It is sort of pretending to be a sinewave oscillator that's being frequency modulated.
- which it has to, because the Blofeld doesn't have enough oscillators to emulate the 6 operators of a DX7 ;-)
By changing the position of the wavetable with velocity sensitivity, the overall sound changes dramatically, which allows for this patch to be played quite expressively."
