Mozzi Output Circuit

As part of the Arduino Multi-pot Mozzi FM Synthesis project I put together a simple Mozzi output filter circuit, but it stopped working. After having a bit of a look and poke about it it turns out that the jack socket was faulty, so I ordered a different type of socket and started again. This is … Continue reading Mozzi Output Circuit →

Arduino MPR121 Touch Piano

This project uses on off-the-shelf capacitive touch shield or module to provide touch-sensitive pads for a 12 (recommended for beginners) to 48 (advanced) note "piano". https://youtu.be/rq7UWVNde8M These are the key Arduino tutorials for the main concepts used in this project: Adafruit MPR121 12-Key Capacitive Touch Sensor Breakout Tutorial Sparkfun MPR121 Hookup Guide Arduino Tone … Continue reading Arduino MPR121 Touch Piano →

Arduino Mozzi String Synth

This project uses a specific configuration of the Arduino Mozzi Additive Synthesis project to create a "synth strings" type sound based on detuned sawtooth waves. https://youtu.be/lHMRKDDTzUc 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! These are the key Arduino tutorials … Continue reading Arduino Mozzi String Synth →

Instant Touch Music

In this project, I'm looking at two "ready to go" boards that provide touch sensitive inputs that can be used to play music. First is the Adafruit Circuit Playground Express and then on to the Bare Conductive Touch Board. For a more "DIY" approach, see Arduino MPR121 Touch Piano. https://youtu.be/VCVvB2rTL4c These are the links to tutorials … Continue reading Instant Touch Music →

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 FM MIDI Synthesis with Mozzi – Part 2

This builds on Arduino FM MIDI Synthesis with Mozzi but bases the code on a different example from the Mozzi library and adds a third potentiometer! Once again, if you are just using the code "as is" this is a beginner project. To get into the detail of the code though takes it into "advanced" territory! … Continue reading Arduino FM MIDI Synthesis with Mozzi – Part 2 →

Arduino FM MIDI Synthesis with Mozzi

This project takes the Mozzi library a bit further and combines the Mozzi example code for potentiometers, FM synthesis and MIDI into one. If you are just using the code "as is" this is a beginner project. To get into the detail of the code though takes it into "advanced" territory! In Part 2 the … Continue reading Arduino FM MIDI Synthesis with Mozzi →

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 →

Arduino PWM MIDI Synthesis with Mozzi

This project uses an off the shelf synthesis library to create complex sounds using pulse-width-modulation (PWM) on one of the Arduino's output pins. For further Mozzi experiments, you can take a look at Arduino FM MIDI Synthesis with Mozzi. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not … Continue reading Arduino PWM MIDI Synthesis with Mozzi →
