Arduino Mozzi Additive Synthesis

This project uses the Mozzi library to add sine waves together in a simple form of additive synthesis. It uses the six potentiometers from the Arduino Multi-pot Mozzi FM Synthesis project. https://youtu.be/bH1698olHXI Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive … Continue reading Arduino Mozzi Additive Synthesis →

Arduino Multi-pot Mozzi FM Synthesis

This project supports up to six potentiometers to change the synthesis parameters of a Mozzi based FM synthesizer. It builds on the previous two Mozzi projects. An alternative synthesizer IO board is developed in Simple Synth IO Shield. A multi-Nano version of this project is described in Arduino Nano Multi-pot FM and String Synthesis. A further update … Continue reading Arduino Multi-pot Mozzi FM Synthesis →

Arduino MIDI Interfaces

This are a mixture of beginner and advanced, DIY and off-the-shelf, options covering MIDI in (receive), MIDI out (send), and USBMIDI to MIDI conversion. All link into the RX and TX pins of your Arduino or other microcontroller. All are designed for 5V logic signals. Here are some other pages of interest: Ready-Made MIDI Modules … Continue reading Arduino MIDI Interfaces →

MIDI In-Out Half-Shield

I have an idea for a project that only uses part of the Arduino's IO so that got me wondering if I could fit a full MIDI shield into half the space of a full shield. Its more of an idle curiosity really as shields will stack and as I've already shown MIDI circuitry can … Continue reading MIDI In-Out Half-Shield →

Mini USB-MIDI to MIDI

This is essentially a remake of my Simple USB-MIDI to MIDI but using a mini MIDI Host Shield and an Arduino Pro Mini, which I've not used before, with a home-made MIDI out interface to make a simple "all in one" unit. https://youtu.be/mHmNyse8uJ0 Warning! I strongly recommend using an old or second hand keyboard for your MIDI … Continue reading Mini USB-MIDI to MIDI →

LOLShield MIDI Waterfall Display

This builds on the Arduino MIDI Note Monitor with a slightly different take to the Wemos MIDI LED Matrix making use of a "LOL Shield". LOL in this case stands for "lots of LEDs" - in this case a grid of 14 x 9 - and is a fun way to get your Arduino lighting up as … Continue reading LOLShield MIDI Waterfall Display →

Arduino R2R Digital Audio – Part 3

So this is where we start to get closer to some proper direct digital synthesis using the hardware developed in part 1 and moving on from the timer-driven code developed in part 2. In Arduino MIDI R2R Digital Audio I add MIDI. In Arduino PWM Sound Output I talk more about the theory of PWM. https://youtu.be/1MPNHMQ-2vs The … Continue reading Arduino R2R Digital Audio – Part 3 →

Arduino R2R Digital Audio – Part 2

Building on the Arduino R2R Digital Audio project, this uses the Arduino Timer functions to run our code in a more accurate and useful way. I've now also added some potentiometers to my shield and a jack output socket. In Arduino R2R Digital Audio - Part 3 the code is developed further to support wavetable synthesis. In Arduino … Continue reading Arduino R2R Digital Audio – Part 2 →

Arduino R2R Digital Audio

This project shows an example of digital to analogue synthesis. Technically this is what is called direct digital synthesis, but in its most basic form. In Arduino R2R Digital Audio - Part 2 I add some control and develop the code further. In Arduino R2R Digital Audio - Part 3 the code is developed further to support … Continue reading Arduino R2R Digital Audio →

Arduino MIDI Touch Piano

Just to complete the set, this is the Arduino Touch Piano – Part 2 stripboard version generating MIDI rather than tones. https://youtu.be/lJJe-0p2Y7k Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! This builds on all the knowledge gained so far … Continue reading Arduino MIDI Touch Piano →
