Auduino MIDI Granular Synthesis

I wanted to return to the Auduino project and add MIDI functionality. This project describes how to add some basic MIDI receiving functionality. https://youtu.be/wBp-Wq_GsrE Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments or gear! These are the key Arduino tutorials … Continue reading Auduino MIDI Granular Synthesis →

Arduino PWM Output Filter Circuit

There have been a number of occasions now where I've added a low-pass filter and voltage divider to my Arduino-based PWM outputs so I thought it was worth pulling that together into a single post to make it easy to refer to elsewhere. This is that post. There is nothing new here, it is just … Continue reading Arduino PWM Output Filter Circuit →

Arduino MPR121 MIDI Touch Piano

A comment on the Arduino MPR121 Touch Piano pointed out that I never went as far as building a 48-note MIDI touch piano. In principle all the bits are there between that post and the Arduino MIDI Touch Piano so this post brings the two together to do just that. https://youtu.be/fdxiHUlXFbY These are the key Arduino … Continue reading Arduino MPR121 MIDI Touch Piano →

Pico MIDI Keypad Mini Tenori-On

I'd love to have a proper Tenori-on. It is a pretty unique kind of electronic instrument with a 16x16 grid of buttons that allows you to draw patterns that are then played in sequence. But as that is very unlikely to ever happen, I have to be content with making my own! Here is a … Continue reading Pico MIDI Keypad Mini Tenori-On →

Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2

Having added USB MIDI to my "Toy Keyboard" - I wanted the option to choose either USB or serial MIDI as the output. This returns to the Toy Keyboard USB Matrix Decode with the Pi Pico project to add a serial port option. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2 →

Arduino Mozzi Sample Drum Sequencer

This project combines the Arduino Mozzi Sample Drum Machine with the code from the Arduino VS1003 Drum Machine and the buttons from the Analog Keypad Tone Controller. https://youtu.be/e_hVGe0Z_mE Warning!

Arduino Mozzi Sample Drum Machine

There is still a lot to explore with the Mozzi synthesis library, so today I wanted to look at the "sample" options - getting the library to play pre-recording samples of sounds. https://youtu.be/eB7vzF_4zxY Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive … Continue reading Arduino Mozzi Sample Drum Machine →

Analog Keypad Tone Controller

I've picked up a couple of cheap 3x4 keypads so thought I'd look at its potential as a music controller. https://youtu.be/C1n5NBVvfLg Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the main concepts used … Continue reading Analog Keypad Tone Controller →

Toy Keyboard USB Matrix Decode with the Pi Pico

I never really got back to looking at my "Toy Keyboard" - I wanted to do the same as the Vintage Phone - create a USB MIDI version with Circuitpython. Well now I have. Here is the result. https://youtu.be/VNmp3-mwysI Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico →

Raspberry Pi Pico MIDI Channel Router

Ever since I got hold of a Raspberry Pi Pico microcontroller I wanted to try out the Programmable Input Output (PIO) peripherals. I've also been on the lookout for microcontrollers with more serial ports than the usual one or two. The best I've found so far are ATmega2560 boards with four and the Teensy range … Continue reading Raspberry Pi Pico MIDI Channel Router →
