Arduino MIDI Rotary Encoder Controller

I've finally gotten around to having a play with rotary encoders. It has been on my "to do" list for a while, so I thought I'd start with a rotary encoder version of my Arduino MIDI Button Controller which can select a voice and send the corresponding Program Change message out over MIDI. https://youtu.be/uxT_RQs1MXM Warning! I strongly … Continue reading Arduino MIDI Rotary Encoder Controller →

PC USB-MIDI to MIDI Revisited

This is another take on the PC USB to Arduino Serial MIDI once again taking the Pro Micro I used in part 2. Recall that the Pro Micro board (not to be confused with the Arduino Micro or the Pro Mini) is an Arduino Leonardo compatible smaller board, using the ATmega32U4, which means it has a … Continue reading PC USB-MIDI to MIDI Revisited →

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 →

Arduino USB MIDI Merge

This project uses two off-the-shelf Arduino shields to provide a USB and Serial MIDI merge to a single Serial MIDI OUT. https://youtu.be/AB49UNDIrcM 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 … Continue reading Arduino USB MIDI Merge →

Arduino MIDI Filter – Revisited

This is a minor update to my Arduino MIDI Filter to allow it initialise patches as well as filter MIDI if required. 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 for the main … Continue reading Arduino MIDI Filter – Revisited →

DIY MIDI Interfaces

This page is a mixture of beginner and advanced, DIY options covering MIDI in (receive), MIDI out (send), and USBMIDI to MIDI conversion for non-Arduino like microcontrollers. Here are some other pages of interest: Ready-Made MIDI Modules - a range of modules for "ready to go" MIDI IN and OUT for both 5V and 3V … Continue reading DIY MIDI Interfaces →

USB-MIDI to MIDI Revisited

Ever since building my Mini USB-MIDI to MIDI I've wanted something a little more self contained. Most of these projects have been built with 8-bit microcontrollers, but the costs of more powerful microcontrollers is coming down all the time and you can now get very powerful 32-bit ARM based boards for really not very much so … Continue reading USB-MIDI to MIDI Revisited →

MIDI In for 3.3V Microcontrollers

I have a number of microcontrollers now that use 3.3V logic: Raspberry Pi Pico Adafruit Feather Adafruit Circuit Playground Express BBC Micro:bit So far, I've look at MIDI OUT functionality, so now its time to look at MIDI IN, based on the circuit from my Simple MIDI Monitor. This project shows how to build your … Continue reading MIDI In for 3.3V Microcontrollers →

Single Pin MIDI Channel Selector

One thing that has been missing from all of my MIDI projects so far is some means of configuring the MIDI channel without having to reload code. There are a number of approaches, but I wanted one that used the minimal amount of IO. This documents one option. In part 2 I build this into … Continue reading Single Pin MIDI Channel Selector →

Pi Pico MIDI Matrix Decode

Having had a first play with my new Raspberry Pi Pico, I thought the next step was to make a simple MIDI controller with some IO. So I thought I'd get a simple music keyboard up and running. In part 2 I build this up on stripboard. In part 3 I expand it to four … Continue reading Pi Pico MIDI Matrix Decode →
