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 →

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 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 →

Arduino MIDI Delay

As mentioned when I made my MIDI In-Out Half-Shield, there are some neat opportunities for MIDI related effects, so this is my MIDI delay implementation. https://youtu.be/rnUY4i4nMPE This is marked "beginner" from the point of view of "just download the code and use it", but if you want to dig into the code it is really in … Continue reading Arduino MIDI Delay →

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 →

WS001 – Tones, Notes and MIDI Out

This is the first of my worksheets collecting together a number of related projects with a single list of parts and a suggested "building order". This worksheet links together the following projects: Arduino Tone Generator Arduino Note Generator Simple Arduino Music Keyboard Arduino Simple MIDI Controller MIDI Patch Button Arduino LDR Pianola Arduino Piezo MIDI … Continue reading WS001 – Tones, Notes and MIDI Out →
