"open e-drums" is a completely open source electronic drum. Pads that can be produced with 3D printers, and midi converters are all open source hardware. Arduino code for sensing is also available. You can create your own e-drum from scratch, or add pads to the Roland and YAMAHA kits.

ABOUT
This project started by accident. At the time, I was a product design student who had used Arduino just a little. When I found a drum mania controller at a used store at a bargain price, I was somehow attracted to it and bought it. This is the beginning of everything. I took it apart and played with Arduino. I used a piezo for the first time at that time. I learned the delicate sensing ability of piezo. I realized the greatness of electronic drums such as Roland, Yamaha, and Alesis, which process the signals beautifully. I want to try it myself.

I didn't have any knowledge of programming or electronics. In other words, I have acquired a lot of knowledge through this project. For some people, this project is just a reinvention of the wheel. But it's a very meaningful project for me. As I proceeded with this project, I drew on the knowledge of many predecessors. Many of them keep information open. That's great. So I decided to publish this project as an open source hardware project. I would be happy if this project helps someone create something."

"I made this keyboard out of a broken Commodore machine and a Arturia MiniBrute keybed.

This thing is not a MIDI controller nor a Arduino / Raspberry Pi design. It uses carbon contacts that act as switches and connect directly on the keyboard matrix inside a Commodore 64.

Because of this, it can be used with ANY programs that allow the musician to play notes directly on the C64's keyboard, allowing you to use a wide vierity of original music programs that were compat"

Programmable #Arduino Synthesizer Watch

Published on Dec 6, 2019 element14 presents

A Buchla for your wrist. Almost gave this one the Synth Rorschach label, but it is a synth after all... Definitely Synth Bling though.

"In 2016 Clem built a very annoying synthesizer in the form of a wristwatch. After showing it around at various Maker Faires it broke, so he decided to rebuild it better louder and more annoying than ever before! It is user-programmable thanks to the Arduino MKR and a haptic interface with satisfying sliders! Download the files for free and make one yourself: http://bit.ly/2DMIKIU"

Playlist:
1. Designing a Eurorack Sequencer - Pt. 1: Digital to Analog

In this new series I'll be designing, prototyping and building a sequencer module for my eurorack sythesizer using the Arduino platform. In this episode, we connect the arduino to our 12v power supply and add a digital-to-analog converter output so our sequencer can output proper 0-8v CV signals.

2. Designing a Eurorack Sequencer - Part 2: Seven Segment Displays

Continuing to design and prototype the Super Sixteen sequencer module for my eurorack sythesizer using the Arduino platform. In this episode, we wire up a seven segment display to show some visual feedback using another serial chip, the I/O expander. Then we take a crack at making our sequencer play a scale!

3. Designing a Eurorack Sequencer - Part 3: Enter the Matrix

Continuing with the Super Sixteen, we build the sequencer's namesake sixteen-button grid, explore matrix wiring and multiplexing in combination, and construct our first working prototype that actually plays a sequence!

4. Designing Eurorack Sequencer Part 4: Making a PCB with KiCad 5.0

In this episode we get into some proper electronics design with KiCad and develop a new layout for a printed circuit board. Then we get to do the fun part and fabricate it at home using a toner transfer and ferric chloride etching.

5. Designing a Eurorack Sequencer - Part 5: Assembly

In this episode we assemble the first PCB prototype of the Super Sixteen with our trusty soldering iron and a spool of mod wire. After a few fried chips and more than a few repairs, it's time to wire it up to our synth and try out some actual sequencing!

6. Designing a Eurorack Sequencer - Part 6: Front Panel and External Sync

Or, "How to Make a Eurorack Front Panel: The Cheap Way"
In this episode we upgrade our module with a faceplate, and add some advanced features like external sync, pitch calibration, and glide/portamento.

7. Designing a Eurorack Sequencer part 7 - New PCBs, Motion Recording, Beat Repeat

In this episode, we assemble, inspect, debug, and reprogram our new dual-PCB stackup for the Super Sixteen eurorack CV sequencer. Not everything goes according to plan!

8. Designing A Eurorack Sequencer Part 8: New panel, Patch memory, Performance effects

In this installment we fabricate a new front panel for the Super Sixteen using the toner transfer process, and then take a spin with some of the new advanced features it sports, like patch memory, scale selection, swing timing, and a gang of performance rhythm effects.

"Ever since childhood I have viewed compact discs as the embodiment of futurism: ideal shape, mirrored surface, and a crystal-clear sound. And I also loved how they would malfunction. Scratches, scuffs, read errors – at a time when I still knew nothing about IDM and glitch music, I tried to engineer a repeat of these sounds, but felt like I was chasing ghosts. And then all of a sudden discs went out of fashion and were forgotten.

As a rule players would only reproduce the sound in play mode. In all other modes, even though the laser continues to read the information on the surface, the sound would zone out. This was done to ensure that the player did not play the errors and did not emit any sound on a pause, the scratch marks, etc.

Recently I stumbled upon a description of one the processors of old Sony CD players, including instructions on how to modify the player so that it continues to emit sounds in any operating mode. Experimentation was not long in coming: I ordered several old Sony D2 and D20 and started my preparations. As the thirty-year old electronics would literally fall apart in my hands, I assembled one operable device from three players. After replacing all the capacitors, I was struck by the sound quality of this player – state of the art MP3 players don’t even come close. The new device is capable of playing any compact discs with profound scratch marks, makes a sound during rewind, on pause and also during the stoppage/start-up of a disc. Furthermore, I added an intercept function for the motors responsible for the movement of the laser head and the rotation of the disc. I also added to the device a digital processor with joystick for evocative manipulations of the sounds obtained from the player. Another option was an additional revolving optical disc. As well as the visual impact, owing to the emergent induction it is capable of influencing at high speed the motor of the CD, which results in fascinating data read errors.

Taken altogether, this made it possible to create a robust instrument for the deconstruction of existing music and also manipulations with discs specially recorded for the experiments. And that is how compact discs suddenly became an extremely topical format for me once more.

Inspired by Nicolas Colins projects.

Bitty - Pocket-sized Drum Machine and Synthesizer by Curious Sound Objects

Published on Apr 30, 2019 Curious Sound Objects

Currently on Kickstarter

via Arduino.cc

"There are a wide variety of ways to create electronic music. For a capable machine that fits in the palm of your hand and is loud enough to use outdoors, however, it’s hard to imagine a battery-powered device cooler than Bitty from Curious Sound Objects.

The pocket-sized drum machine and synthesizer, currently on Kickstarter, was prototyped using an Arduino Nano and will be fully Arduino-compatible when released. This means that in addition to changing the sound and interface around with readily-available sound packs—which include Theremin Bitty, Techno Bitty, Basement Bitty, Trap Bitty, Lofi Bitty, and Beach Bitty—it can be programmed with the Arduino IDE. The device can even run sound software written for other Arduino boards.

Bitty features four sample trigger buttons, a pair of knobs, and a speaker. Designed for entry-level EDM enthusiasts and studio musicians alike, you can play the drums and melodies manually, as well as trigger patterns to produce dance music or hip hop beats. These can be chosen via the left knob, while the right knob handles pitch, note selection, and arpeggiation."

"more about - http://vtol.cc/filter/works/Poise-d

Poise→[d] is a hybrid installation that uses chemical and physical reactions to control its behaviour and sound synthesis. The installation consists of the main control unit and three balancing robots. The main control unit has three core systems where the reactions occur, with everything analysed by a computer algorithm using cameras.

This project is based on self-organising structures viewed from several different angles. All the three robots are connected to the main control unit and represent through sound and movement one of the three processes that are happening. The first robot is connected to a sound/mechanical process, the second one to a thermodynamic reaction, and the third to a chemical reaction. Taken together, they create a new and more complex system, as they affect each other through the movements of robots and the main algorithm. To a certain extent, this hybrid system consisting of robotised kinetic objects and chemical/physical reactions is symptomatic of pre-biotic chemical evolution. Another important aspect is the use of Belousov-Zhabotinsky’s chemical reaction - owing to its complexity and singularity, fascinating studies were conducted on cybernetics and some scientists were even enthused to create a chemical computing machine. In this project, the reaction is the most important component of the algorithmic process of the entire installation."

Autumn Leaves - A piano improv on a Launchpad Pro & with an Arduino

Published on Nov 10, 2018 Lanthan O'Ide

"Just a little piano improvisation, but played on a Launchpad.
I hope you'll enjoy it! ^^
================================
Since realistic piano playing is hard without a sustain pedal, I built my own custom MIDI controller.
With it I can attach a sustain & expression pedal to any MIDI controller.
Pretty neat, huh? ;-)

It has a MIDI input and output, and two pedal inputs.
The Arduino Uno inside it just passes any MIDI messages from the input to the output,
and also sends CC messages if a pedal has been pushed or released.
So I can just put it between any keyboard and synth.

The four buttons & lights on the right specify the MIDI channel for the pedals.
(In binary, of course ;-) )

The LED on the left lights up when a sustain pedal is pushed down."
