Having built my adaptor into a small box, I've gone back to add a mode button so I can include all the different applications into a single sketch. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 7

Arduino USB MIDI Mux Pot Controller
The other application I wanted for my Arduino USB MIDI Mux Step Sequencer is as a general purpose MIDI controller. In this case with 16 potentiometers mapped to MIDI CC messages. This is building on the following previous projects: Arduino USB MIDI Mux Step Sequencer Arduino and USB MIDI “Bare Metal” Raspberry Pi Synth – Part … Continue reading Arduino USB MIDI Mux Pot Controller
Vintage Rotary Phone MIDI Controller – Part 6
In this final (for now) post, I'm just tidying up the circuit and using a Pro Mini to embed all the electronics I need into a nice small box. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the … Continue reading Vintage Rotary Phone MIDI Controller – Part 6
Vintage Rotary Phone MIDI Controller – Part 5
In this post, I describe how to use my rotary phone as a simple random-note MIDI "sequencer" of sorts. The triggering of the notes is driven from the pulses of the dial. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 … Continue reading Vintage Rotary Phone MIDI Controller – Part 5
Vintage Rotary Phone MIDI Controller – Part 4
In this post, I describe how to use my rotary phone as a MIDI program changer. This builds on the previous parts in this series. Part 1 – Understanding the telephone hardware and interfacing to an Arduino. Part 2 – Decoding the rotary dial from the Arduino. Part 3 – Rotary phone MIDI note controller. Part 4 – Rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 4
Vintage Rotary Phone MIDI Controller – Part 3
This is the first musical application of my vintage rotary phone. I'm using it as a simple MIDI note generator. Remember, I really wanted to keep this as a potentially working phone when not plugged into an Arduino. This builds on the previous parts in this series. Part 1 – Understanding the telephone hardware and interfacing … Continue reading Vintage Rotary Phone MIDI Controller – Part 3
Raspberry Pi Pico Multi MIDI Router – Part 2
One thing I've wanted to do since building my Raspberry Pi Pico Multi MIDI Router is build a board a bit like ones DeftAudio produces for the Teensy. This posts describes a DIY version of a 4+2 IN, 4+2 OUT MIDI board for the Raspberry Pi Pico. Warning! I strongly recommend using old or second hand … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 2
Raspberry Pi Pico MIDI Pedal Keyboard
Quite a number of years ago, I found an old set of organ pedals and MIDI'd them up by the crude method of wiring the pedal switches onto the connectors for the keys of an old Amstrad MIDI keyboard... It was the technology and expertise I had at the time! I stumbled across them a … Continue reading Raspberry Pi Pico MIDI Pedal Keyboard
Arduino MIDI Channelizer
This project kicked off from a comment in the "Audio/Midi/DMX using Arduino" Facebook group, where someone wanted to know if an Arduino could receive messages on one channel and change the channel number and send them back out. The answer is yes and this is how it could be done. I've based it on my Arduino … Continue reading Arduino MIDI Channelizer
Raspberry Pi Pico I2C MIDI Interface – Part 4
For this final (for now) part of my experimenting with my Raspberry Pi Pico I2C MIDI Interface, I've set it up to talk to multiple Arduino's, each with a speaker to act as an I2C MIDI "tone module". In part 1, I tested the concept of a Pico I2C MIDI interface. In part 2, I … Continue reading Raspberry Pi Pico I2C MIDI Interface – Part 4
